EFFECT OF VARIOUS STRUCTURAL & SITE SPECIFIC PARAMETERS ON BEHAIVOUR OF R.C.C FRAMED BUILDINGS IN SIESMIC CONDITIONS

Abstract

Buildings are the utmost important part of human survival, and study has revealed that large number of buildings in India is severely deficient against earthquake forces and the number of such buildings is growing very rapidly. Safety of the life in the seismic event is the prime consideration of earthquake resistance design Philosophies. Experience from the past earthquake has shown that much loss of the life and property results due to inadequacies and faulty practices in seismic design of the structures. To capture the real behavior of buildings, advanced analysis (seismic analysis) of the buildings is required. This dissertation work describes the dynamic Analysis of the buildings using program in STAAD Pro with various structural and site specific parameters. Nine different RCC building models have been generated from 2 storey to 10 storey all having the same configurations in terms of floor plan at each level with same loading as well as same geometric and material properties (keeping the same stiffness in all the building models)considering in seismic Zones IV and V with all the three soil site parameters (Hard ,Medium and Soft soil) as recommended by IS codes are analyzed in STAAD Pro using Response spectrum Method and variations in responses in all the buildings in terms of base shear, storey shear, mass participation , frequency, time period has been observed.
