ABSTRACT:
Constructions made of shear walls are high in strength ,they majorly resist the seismic force, wind forces and even can be build on soils of weak bases by adopting various ground improvement techniques. Not only the quickness in construction process but the strength parameters and effectiveness to bare horizontal loads are very high. Shear walls generally used in high earth quake prone areas, as they are highly efficient in taking the loads. Not only the earth quake loads but also winds loads which are quite high in some zones can be taken by these shear walls efficiently and effectively.
Shear walls have a peculiar behavior towards various types of loads. Calculation of rigidity factor, reactions, shear center, shear force and bending moment is a topic of interest. To determine the solution for shear wall location in multi-storey building based on its both elastic and elasto -plastic behavior’s. The earthquake load is to be calculated and applied to a multistoried building. Model results are calculated and analyzed for the effective location of shear wall. Hence by adopting the shear wall technologies to the college building of VITS block, Deshmukhi Hyderabad city. The building behavior is checked.
The design is above verified for this same structure using extended three dimensional analysis of buildings (STAAD Pro V8i) software.The results are compared. It is found that the provision of shear wall in this building will make this structure completely earth quake resistant in zone II of Hyderabad. Further it is also found that the results of manual and STAAD Pro are almost same, the STAAD Pro giving a little bit of saving in the reinforcement quantity.
