&lt;br /&gt;
= Introduction =&lt;br /&gt;
&lt;br /&gt;
Steel structures are formed from a skeleton frame that consist of vertical columns, horizontal beams and so on made from steel materials, riveted, welded or bolted together, often in a rectilinear grid. Steel structures are typically used for medium and high-rise, industrial, warehouse and residential buildings.&lt;br /&gt;
&lt;br /&gt;
Advantages of steel structures include:&lt;br /&gt;
&lt;br /&gt;
* Resilience to earthquakes and wind loading.&lt;br /&gt;
* Ease of construction and deconstruction.&lt;br /&gt;
* Short construction time.&lt;br /&gt;
* Resistance to fire when treated.&lt;br /&gt;
* Can be used in combination with other types of construction.&lt;br /&gt;
* Easy to join.&lt;br /&gt;
* High precision.&lt;br /&gt;
* Offsite fabrication.&lt;br /&gt;
* High ratios of strength to weight and strength to volume.&lt;br /&gt;
* Permit long clear spans.&lt;br /&gt;
* Narrow columns.&lt;br /&gt;
* Can be made to be exposed&lt;br /&gt;
&lt;br /&gt;
= Steel structural systems =&lt;br /&gt;
&lt;br /&gt;
The main steel buildings elements include walls, floors, roofs and bracing members can be arranged to have a certain type of system that aids in the structural stability of the building depending on the type or use of the building, the nature and intensity of the applied loads and the design life required&lt;br /&gt;
&lt;br /&gt;
== Wall bearing framing ==&lt;br /&gt;
&lt;br /&gt;
Wall bearing framing involves the erection of masonry walls on the perimeter and interior of the building and the structural steel members are then anchored on the masonry walls using bearing and end steel plates and anchor bolts. The design and construction of the wall bearing framing depends on the load intensity and the span distance between successive supports.&lt;br /&gt;
&lt;br /&gt;
While lower depth beams help to increase the clear headroom height of the building it also poses a requirement for the closer spacing of the columns and hence limits the clear floor space area. On the other hand, deep beam frames help to span long distance.&lt;br /&gt;
&lt;br /&gt;
== Skeleton framing ==&lt;br /&gt;
&lt;br /&gt;
This is the column – beam structural framework system, in which all the lateral and gravity loads are transmitted to the steel framework and transferred down to the foundation. Walls are made as a curtain wall with no load bearing. Skeleton framing typically comprises of spandrel beams, main or primary beams, intermediate or secondary beams, wall columns and interior columns and reinforced concrete slab. For eccentric connections between column and beams there are a lot of techniques involved such as the use of metal brackets, gusset plates and haunches which help to distribute the induced stresses. Shims help in making line and elevation adjustments. Shelve angle brackets help in attaching the spandrel beam and column.&lt;br /&gt;
&lt;br /&gt;
== Long-span framing ==&lt;br /&gt;
&lt;br /&gt;
A long span is a span that exceeds 12m. It helps to provide a flexible floor space, column free internal spaces, reduction in the on-site construction period, allows for installation of multiple services and mixed use of spaces. It is typically used for large industrial buildings, auditoriums, theatres, exhibition spaces and so on.&lt;br /&gt;
&lt;br /&gt;
The following techniques are used; stub girders, hunched composite beams, composite trusses, cantilever suspensions spans, folded plates, curvilinear grids, thin shells domes, cable networks, space trusses, portal frames and so on.&lt;br /&gt;
&lt;br /&gt;
= Girders =&lt;br /&gt;
&lt;br /&gt;
These are deep steel beams which help to span long distances. The spanning length depending on the girder steel grade and the span depth ratio. Girders are installed in different ways, there are stub girders which span longitudinally across the structures being connected to the main girders and the hybrid girders, these are the manipulated girders stiffened to carry higher amount of loads by addition of the welded parts in the both top and bottom flanges.&lt;br /&gt;
&lt;br /&gt;
= Trusses =&lt;br /&gt;
&lt;br /&gt;
Trusses have the advantage of spanning long distances due to the greater depth they possess making them stiff against deflections. The types of trusses used for long span construction includes Pratt trusses, Warren Trusses, Fink Trusses, Scissors, Bow String and Vierendeel Trusses. For more information see: Truss.&lt;br /&gt;
&lt;br /&gt;
These truss forms can be used as the main supporting structural members in floor and roof framing systems.&lt;br /&gt;
&lt;br /&gt;
= Rigid frames =&lt;br /&gt;
&lt;br /&gt;
The degree of rigidity in the beam-column connections must be carefully analysed. In rigid frames connections are designed to bear both bending moment and shear forces. They are designed as full continuous frames through the whole length and height in the absence of the hinges or pins in the crowns and in mid-span.&lt;br /&gt;
&lt;br /&gt;
Large rigid foundations help to carry and distribute the moment and shear to the ground. For economical reasons the ground conditions should be checked as it could lead to higher foundations costs in poor subsoil conditions.&lt;br /&gt;
&lt;br /&gt;
= Arches =&lt;br /&gt;
&lt;br /&gt;
Arches can be made as solid arches or open web arches, three hinged, two hinged or fixed arches. These depend on the type of structural materials to be used, strength capacities, anchorage, building use, foundation type and the loading conditions.&lt;br /&gt;
&lt;br /&gt;
The three hinged arch can help to span long distances even when there are adverse conditions such as poor climate, heavy loaded structures and so on. Two pinned arches are less strong compared to three hinged arch structures. Fixed arches are used in buildings with lighter loads and good ground conditions.&lt;br /&gt;

These are deep steel beams which help to span long distances. The spanning length depending on the girder steel grade and the span depth ratio. Girders are installed in different ways there are stub girders which span longitudinally across the structures being connected to the main girders and the hybrid girders these are the manipulated girders stiffened to carry higher amount of loads by addition of the welded parts in the both top and bottom flanges.&lt;br /&gt;
&lt;br /&gt;
= Trusses =&lt;br /&gt;
&lt;br /&gt;
Trusses have the advantage of spanning long distances due to the greater depth they possess making them stiff against deflections. The types of trusses used for long span construction includes Pratt trusses, Warren Trusses, Fink Trusses, Scissors, Bow String and Vierendeel Trusses. For more information see: Truss.&lt;br /&gt;
&lt;br /&gt;
These truss forms can be used as the main supporting structural members in floor and roof framing systems.&lt;br /&gt;
&lt;br /&gt;
= Rigid frames =&lt;br /&gt;
&lt;br /&gt;
The degree of rigidity in the beam-column connections must be carefully analysed. In rigid frames connections are designed to bear both bending moment and shear forces. They are designed as full continuous frames through the whole length and height in the absence of the hinges or pins in the crowns and in mid-span.&lt;br /&gt;
&lt;br /&gt;
Large rigid foundations help to carry and distribute the moment and shear to the ground. For economical reasons the ground conditions should be checked as it could lead to higher foundations costs in poor subsoil conditions.&lt;br /&gt;
&lt;br /&gt;
= Arches =&lt;br /&gt;
&lt;br /&gt;
Arches can be made as solid arches or open web arches, three hinged, two hinged or fixed arches. These depend on the type of structural materials to be use, strength capacities, anchorage, building use, foundation type and the loading conditions.&lt;br /&gt;
&lt;br /&gt;
The three hinged arch can help to span long distances even when there are adverse conditions such as poor climate, heavy loaded structures and so on. Two pinned arches are less strong compared to three hinged arch structures. Fixed arches are used in buildings with lighter loads and good ground conditions.&lt;br /&gt;

&lt;div&gt;= Six new Regulations under the Building Safety Act 2022 =&lt;br /&gt;
&lt;br /&gt;
On August 17, 2023, The Department for Levelling Up, Housing and Communities (DLUHC) published six Regulations under the Building Safety Act 2022, which stemmed from the earlier consultation responses (see below). Primarily these cover what is called a new building control regime, for specific buildings of higher risk. As such from October 2023, the Building Safety Regulator is the building control authority for higher-risk buildings. Principal designers, principal contractors, and clients have to follow the new building control regime when designing and constructing higher-risk buildings, or undertaking building work to an existing higher-risk building.&lt;br /&gt;
&lt;br /&gt;
The first three of the new regulations relate more directly to responsibilities at the design and construction stages of new and existing projects. All six documents are listed below with direct links, whilst short summaries are provided below.&lt;br /&gt;

= Higher-Risk Building Procedures =&lt;br /&gt;
&lt;br /&gt;
[[w/index.php?title=W/index.php%3Ftitle%3DThe_Building_Regulations_(Higher-Risk_Building_Procedures)_(England)_2023%26action%3Dedit%26redlink%3D1&amp;amp;action=edit&amp;amp;redlink=1|The Building Regulations (Higher-Risk Building Procedures) (England) 2023]], sets out the process and building control regime for higher-risk buildings, including new buildings and works to existing buildings.&lt;br /&gt;
&lt;br /&gt;
The new Building Safety Regulator (BSR) will have powers to approve or stop the construction of new buildings with what is called a hard stop. Referred to as a Gateway 2 process for all Higher-Risk Buildings (HRB) buildings where by an application and approval must be sought from the BSR before work can commence.&lt;br /&gt;
&lt;br /&gt;
Explanation of the procedures for any 'notifiable' or 'major' changes, as well as custody directions concerning the golden thread of information, including handover the duty holders responsible for the building maintenance on completion. It also includes mandatory requirements for occurrence reporting systems and procedures for reporting to the BSR.&lt;br /&gt;
&lt;br /&gt;
Finally the final stages or Gateway 3 describes the procedures and requirements of completion certificates&lt;br /&gt;
&lt;br /&gt;
= Changes applicable to all buildings =&lt;br /&gt;
&lt;br /&gt;
[https://www.legislation.gov.uk/uksi/2023/911/contents/made The Building Regulations etc. (Amendment) (England) Regulations 2023] concerns all building works including HRBs, with new regulations (11A to 11Q). These are primarily concerned with competence requirements of the duty holders, as well as more clearly defining new definition what is to be treated as being the &amp;amp;quot;commencement&amp;amp;quot; of work.&lt;br /&gt;
&lt;br /&gt;
= Building Safety Regulator for all Higher-Risk Buildings =&lt;br /&gt;
&lt;br /&gt;
[https://www.legislation.gov.uk/uksi/2023/906/contents/made The Building (Approved Inspectors etc. And Review of Decisions) (England) Regulations 2023] defines clearly that local authorities and approved inspectors will no longer be able to supervise higher-risk building works, and that the Building Safety Regulator (BSR) is the only building control authority able to be engaged on for all Higher-Risk Buildings (HRBs)&lt;br /&gt;
&lt;br /&gt;
= Consequential amendments =&lt;br /&gt;
&lt;br /&gt;
[https://www.legislation.gov.uk/uksi/2023/908/contents/made The Building Safety Act 2022 (Consequential Amendments etc) Regulations 2023] simply amends some local acts and the Highways Act 1980, the Clean Air Act 1993 to align in terminology and approach to that of the Building Safety Regulator (BSR) including procedures for appeals etc.&lt;br /&gt;
&lt;br /&gt;
= Accountability in occupation =&lt;br /&gt;
&lt;br /&gt;
[https://www.legislation.gov.uk/uksi/2023/907/contents/made The Higher-Risk Buildings (Management of Safety Risks etc) (England) Regulations 2023] is concerned with the management of safety risks during the building's occupation, and the obligatory procedures that BSR, principal accountable and accountable persons, as well as residents and others must follow.&lt;br /&gt;
&lt;br /&gt;
= Charging and financing =&lt;br /&gt;
&lt;br /&gt;
[https://www.legislation.gov.uk/uksi/2023/965/contents/made The Building Safety (Regulator's Charges) Regulations 2023] simply sets out the approach that will be taken to charging by the Building Safety Regulator, in order to recover the costs incurred in the fulfilment of statutory functions for the new building control regime.&lt;br /&gt;
&lt;br /&gt;
= Further Guidance =&lt;br /&gt;
&lt;br /&gt;
Further guidance can be found here: &amp;amp;quot;Building Control: An overview of the new regime; Gateways 2 and 3 – application to completion certificate.&amp;amp;quot; [https://www.hse.gov.uk/building-safety/assets/docs/regime-overview.pdf https://www.hse.gov.uk/building-safety/assets/docs/regime-overview.pdf]&lt;br /&gt;
&lt;br /&gt;
= Original consultation for the new building control regime =&lt;br /&gt;
&lt;br /&gt;
In August 2023, the UK Government published its consultation response &amp;amp;quot;Government response to the consultation on implementing the new building control regime for higher-risk buildings and wider changes to the building regulations for all buildings&amp;amp;quot;. The original consultation was published on 20 July 2022 seeking views on proposals for improving the building control regime for higher-risk buildings and wider changes to the building regulations&lt;br /&gt;
&lt;br /&gt;
A new regime for higher-risk building work was a fundamental part of Dame Judith Hackitt’s recommendations in her Building a Safer Future Report, commissioned by the government after the Grenfell Tower tragedy.It is something the government have said they are committed to implementing and in July 2021 the Department for Levelling Up, Housing and Communities (then the Ministry of Housing, Communities and Local Government) introduced the Building Safety Bill in Parliament, it received Royal Assent and became an Act of Parliament on 28 April 2022. The consultation related to changes to the Building Regulations 2010 that will be made using powers in the Building Safety Act 1984 as amended by the Building Safety Act 2022. Proposals included in the consultation were:&lt;br /&gt;
&lt;br /&gt;
* new duty holder roles and responsibilities in the building regulations to ensure a stronger focus on compliance with the regulations&lt;br /&gt;
* a series of robust hard stops (‘gateway points’) to strengthen regulatory oversight before a higher-risk building is occupied&lt;br /&gt;
* regulator’s notices&lt;br /&gt;
* building work carried out in existing higher-risk buildings (refurbishments)&lt;br /&gt;
* a stronger change control process for higher-risk buildings&lt;br /&gt;
* regularisation of unauthorised building work&lt;br /&gt;
* golden thread of information – having the right people at the right time to have information to support compliance with all applicable building regulations&lt;br /&gt;
* mandatory occurrence reporting&lt;br /&gt;
* more rigorous enforcement powers. A wider and more flexible range of powers will be created to focus incentives on the creation of reliably safe buildings from the outset. This includes compliance and appeals&lt;br /&gt;
* wider changes to the building regulations to align the existing system with the new system&lt;br /&gt;
* transitional provisions for higher-risk buildings&lt;br /&gt;
&lt;br /&gt;
The provisions are being implemented through secondary legislation (The Building (Higher-Risk Buildings Procedures) (England) Regulations 2023 and The Building Regulations etc. (Amendment) (England) Regulations 2023) were laid Parliament on 17 August 2023 these included.&lt;br /&gt;
