Using ETAB software, analyse and compare high-rise buildings (G+40) subject to the combined effects of wind load and earthquake

Abstract

A high-rise building with a lengthy lifespan may face one or more significant risks. Specifications have traditionally taken into account the different severe risks independently, based on the governing load scenario. Because of this, it is challenging to forecast how well high-rise buildings built in accordance with current regulations will fare against the combined threat of wind and earthquakes. This study uses ETAB software to analyze and compare high-rise buildings (G+40) that are vulnerable to the combined effects of wind and earthquake loads.  Because they use high-strength materials and have efficient structural systems, modern tall structures are more flexible and thin with less damping. This leads to a reduction in building height. For the occupants of the building, this sensitivity to wind excitation and seismic stress makes these flexible constructions uncomfortable. In order to lessen this excitation and improve the tall structures' resilience to wind and seismic loads, numerous investigations and studies have been conducted. According to numerical calculations, the degree of damage can affect the lateral force, storey shear, storey drift, storey displacement, overturning moment, and contributions of each hazard scenario.
