SEISMIC ANALYSIS AND UPGRADATION OF STRUCTURES USING LATERAL SYSTEMS

The basic principles of design for vertical and lateral loads (wind & seismic) are the same for low, medium and the high rise building. And building gets high both vertical load & lateral loads become controlling factors. Vertical loads are directly proportion with the increase in floor area with the number of floors. In this contrast, the effect of lateral forces on a building is not linear and increase rapidly with rise in height. Lateral loads and moments on steel components will be very much high. Bracing r educes moments In the present analysis, a residential building with 12 floors is analyzed with columns; columns with V bracings at different locations were for all the cases. And Moments, Base Shear, Displacement, storey shear were compared for all the ca ses. The deflection was reduced by providing the bracings. Earthquake load is becoming a great concern in our country as because not a single zone can be designated as earthquake resistant zone. The most important point is to construct a building structur e that can resist the seismic loads efficiently or not. Research Study has been made on the different structural arrangement to find out the most optimized solution to produce an efficient safe earthquake resistant building. A commercial package ETABS has been utilized for analyzing high - rise building of 36m height. Result has been compared by using tables & graph to find out the most optimum solution. Conclusion has been made on the basis of this analysis & comparison
