−	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 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.	+	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.

−	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.
