LATERAL LOAD ANALYSIS OF OUTRIGGER AND BELT TRUSS SYSTEMS

Abstract

In recent time Reinforced concrete framed structures have gained lots of attention especially in urban areas of metropolitan. Lots of research work is going on in the analysis and safe design of R.C high rise structural frames, due to scarcity of land or due to small FSI (floor space index) in the cities buildings are evolving vertically that is multi-storeyed or high rise buildings. Response of high rise buildings are quite different then multi-storeyed buildings because high rise building suffer lots of lateral drift or lateral displacement and their lateral stability is a great concern in seismic and wind design keeping in view the lateral stability of high rise building. Seven models of RC structural frames with different configuration in ETABS have been made; the main aim of the study is to find out
which structural configuration is more stable against the lateral forces. Outriggers and belt trusses of different type and different materials at different locations have been in cooperated in the building models so as to improve the lateral stability.
