Seismic Study on Tall Structures with RC Shear Walls: Static and Dynamic Analysis

Abstract

Structural design is the primary aspect of civil engineering. In India, multi-storied buildings are usually constructed due to high cost and scarcity of land. In order to utilize maximum land area, builders and architects generally propose symmetrical as well as asymmetrical plan configurations. The asymmetrical plan buildings, which are constructed in seismic prone areas, are likely to be damaged during earthquake. Earthquake is a natural phenomenon which can generate the most destructive forces on structures. Buildings should be made safe for lives by proper design and detailing of structural members in order to have a ductile form of failure. The concept of earthquake resistant design is that the building should be designed to resist the forces, which arises due to Design Basis Earthquake, with only minor damages and the forces, which arises due to Maximum Considered Earthquake, with some accepted structural damages but no collapse. This present analytical study comprises of seismic analysis various stored R.C. structures (from low-rise to mid-rise to high-rise) with regular or symmetrical plan. The following building models such as G+1, G+4, G+9 and G+24 storeyed have been taken into account. The building is modelled as a 3D space frame with six degrees of freedom at each node using the software STAAD PRO v8i v 14.2.4. All the building models are analysed using Equivalent Static analysis. The building models are located in zone IV with S.M.R.F. Furthermore, Response Spectrum Analysis is also conducted on the entire regular plan building models as well as irregular plan building models. Detailed seismic response and behavior are discussed well in this present study.
