Seismic Analysis Of Asymmetrical Multistoried R.C. Structures Using Shear Wall In Severe Seismic Zones As Per Is 1893:2016

Shear walls have very high in-plane stiffness and strength, which can be used to simultaneously resist large horizontal loads and support gravity loads, making them quite advantageous in many structural engineering applications. Structures must perform safely when subjected to numerous types of loading while still remaining aesthetic and fully functional. The nature of shear wall design in building structures is a difficult task, particularly if one wants to place the shear walls in such a way that the cost is minimal while still satisfying specific performance objectives when subjected to natural and human-induced loads. This study was conducted to study the effects of shear wall in the multi-storey buildings for different height, study on nodal displacement and storey drift of the building for different cases been carried out. Nodal displacement of stories and storey drift under consideration were evaluated using structural analysis software in accordance with IS 456:2000, IS 1893:2016 and IS 13920. Structures with asymmetric distribution of mass and stiffness undergoes torsional motions during earthquake. The performance of the structures is assessed as per the procedure prescribe in IS 1893:2016. To assess the seismic effect on the structures in the present study, different models with regular and plan irregularities were prepared and analyzed using Etabs 2018 software. For the purpose of study, regular and irregular buildings of G + 12 storeys with same columns sizes subjected to gravity loads and seismic loads are analysed using linear static analysis.
