Calculation of high-rise building structures subjected to earthquake loads - numerical study

Abstract

Abstract: An earthquake is a natural disaster. When an earthquake occurs, there will be huge losses in people and buildings. Although Vietnam is outside the Pacific earthquake belt, recent studies have shown that Vietnam still contains hidden risks of earthquakes. The recent earthquakes in Lai Chau, Dien Bien, and Nghe An are manifestations of that risk. The article uses ETABS software to calculate high-rise building structures subjected to earthquake loads, and studies the changes in internal forces as well as displacements of elements and element nodes when changing the stiffness of the floors and walls.
