Seismic Behavior Analysis of High-rise Connected Structure

Abstract

In recent years, high-rise connected structure is a structure form that is used widely, in order to research the structure's dynamic characteristics, and improving the structure's seismic performance. This paper adopts large finite element software ANSYS to establish finite element model of high-rise connected structure, uses dynamic time history analysis method for seismic response calculation, and analyses and explain calculation results. Through the analysis, under the action of Tianjin wave, the maximum horizontal displacement value of high-rise connected structure's 23rd floor is 0.07765m, it appears in 2.26s; under the action of Tianjin wave, the maximum horizontal acceleration value of high-rise connected structure's 23rd floor is 1.90251m/s 2 , it appears in 1.64s. Research results show that seismic behavior of high-rise connected structure is good, can satisfy the engineering requirement and as well as can provides a certain theoretical basis for seismic design of high-rise connected structure.
