Seismic Performance of high-rise Buildings with Different Structural Systems

In the present world scenario, construction of high rise building is being preferred due to rapid increase in the cost of land, lack of land availability and also to preserve land in rural areas for agricultural use. The design of high rise buildings is primarily governed by wind and seismic loads. The performance of the buildings depends on the structural configuration and the present study aims at comparing the performance of high rise building with different configurations. In the present study, high rise buildings have been investigated under the effect of seismic loads with different structural, namely, (i) special moment resisting frames (ii) frame-shear wall buildings (iii) outrigger systems (iv) braced model . The building models are assumed to be located in Guwahati, Assam which is one of the most earthquake-prone zones in India A detailed analysis of the building system is done by modeling the geometry, material section properties and boundary conditions. All the analysis and design work is conducted using ETABS 2016 version. The post analysis consist typical characteristic comparison related to storey displacement, storey drift, Story Shears. Etc
