Analysis of A Tall Twin Tower Considering Lateral Load as Per I.S. 1893 : I : 2016 Using ETABS

Abstract

In order to better comprehend the structure's dynamic properties and seismic performance, high-rise linked structures have recently gained popularity as a structural type. Earthquakes have historically resulted in extensive instability and structure devastation. Modern buildings are gradually subjected to more seismic force as their height and volume rise. Seismic design has grown to be a vital component of the structure's analysis and design in order to prevent severe damage and guarantee safety. In traditional seismic design, increasing stiffness of the building is usually adopted to reduce the structural response during an earthquake. This approach is usually costly, and the effect of practical application is not obvious, which could not fundamentally enhance the bearing capacity of the structure. Utilizing existing research, a theoretical and physical model of a symmetrical, joined twin tower has been created. Meanwhile, a practical design that makes use of damping vibration absorbers with energy-dissipating capabilities also makes use of the movement of additional weight to lower vibration amplitude of the main body structure. The analysis and verification of the model of a symmetrical, linked twin tower's bearing capacity using a shaking table test enhances the building's seismic performance. It supports creative and useful design concepts in the seismic structural design of symmetrical conjoined twin tower.
This study uses the robust finite element programme ETABS to create a finite element model of a connected high-rise structure, calculates seismic response using the dynamic response spectrum analysis approach, and then analyses and explains calculation findings. According to research findings, high-rise connected structures have good seismic behaviour, can satisfy engineering requirements, and can also offer a theoretical foundation for seismic design.
