Investigation of Linear Dynamic Analysis and Duc-tile Design of High Rise Structure as per Revised Indian Code

Abstract

Abstract: This thesis gives a comparative seismic analysis of high rise structure in zone III and zone IV using the New IS 13920- 2016 standards. The recent earthquakes in India revealed unequivocally that conventional structural design and construction techniques fail to meet fundamental seismic resistance standards. The use of ductile design and detailing methods in conventional construction is a critical topic that requires attention. The ductility of reinforced concrete structures as a whole is a difficult topic. However, specific design factors and reinforcing details may be used in particular critical spots of the building structure to reduce seismic damage and life-threatening collapse. The approaches are straightforward, affordable, and extensively detailed in the Indian Bureau of Standard Code of Practice's standard code of practise (IS13920). It is recommended to conduct a comparative analysis of the dynamic behaviour of high-rise structures using the response spectrum approach in accordance with IS 1893 Part1-2016 The investigation of characteristics including displacement, base shear, and tale drift. Examining factors including modal frequencies and acceleration in response spectrum load instances in both the X and Y directions. Ductile design of high rise structures in accordance with IS 13920-2016's new codal requirements. Additionally, it is recommended to analyse and design multi-story buildings using computational software such as ETABS and compare characteristics such as storey displacement, base shear and storey drift. The shear wall at the corner reduces storey X displacement by 46.245%. The intermediate shear wall reduces displacement by 54.617%. The central shear wall reduces displacement by 68.72%. Lower level shear wall displacement is central. Shear wall at corner reduces storey drift in X direction by 49.374%. Shear wall at centre reduces drift by 39.716%. Shear wall at centre reduces drift by 2.638%. Lower story drift in central shear wall. Shear wall at corner base shear drift is 63.646% greater than without shear wall. Base shear is 64.006% higher with a middle shear wall. Shear wall at the centre increases base shear by 65.765%. Center shear wall has stronger base reaction.
