Abstract-A multi storey building is a building that consists has multiple floors above ground in the building. Multi-storey buildings aim to increase the floor area of the building without increasing the area of the land and saving money. Analysis of multi-storey building frames involves lot of complications and edacious calculations by conventional methods. To carry out such analysis is a time-consuming task. Substitute frame method for analysis can be handy in approximate and quick analysis instead of bidding process. Till date, this method has been applied by designers for vertical loading conditions. The represented plan given to office purposes can accommodate with minimum facilities. Generally, buildings may be failed by bending moments, shear forces acting on members of the building. By keeping these failures in mind, we designed beams, columns, footings by considering maximum loads on members. For loads calculation, substitute frame method is used for reducing the complexity of calculations and saving time. We know R.C structural system is most common nowadays in urban regions with multi-bay and multi-storey’s, keeping its importance in urban regions especially, A building frame consists of number of bays and storey. A multi-storey, multi- paneled frame is a complicated statically intermediate structure. A design of R.C building With and without shear wall of G+15 storey frame work is taken up. The building in plan (30m x 20m) consists of columns built monolithically forming a network. The design is made using software on structural analysis design (STAAD-PRO). The building subjected to both the vertical loads as well as horizontal loads. The vertical load consists of dead load of structural components such as beams, columns, slabs etc and live loads. The horizontal load consists of the wind forces thus building is designed for dead load, live load and wind load and seismic loads as per IS 875. The building is designed as two-dimensional vertical frame and analyzed for the maximum and minimum bending moments and shear forces by trial-and-error methods as per IS 456-2000. The help is taken by software available in institute and the computations of loads, moments and shear forces and obtained from this software.
