Research of Seismic Testing and Dynamic Character of High-rise Building Structure Based on ANSYS

Abstract

With the rapid development of high-rise buildings, many of the architectural buildings were this kind of form for the bottom the podium and upper towers. The emergence of these complex architectural forms has brought many new problems to the seismic analysis of structures and seismic design. This paper describes the building seismic theory on a trial basis, using the ANSYS general purpose finite element software for seismic analysis of the tall building structures. Then we build the actual finite element model to simplify the steel structure concrete columns, and the analysis structure of the static condition. According to second phase of the seismic design, the first phase of multi-elastic was analyzed on earthquake effect of the structure. The dynamic characteristics of the entire structure were determined with modal analysis. The main three incentive direction and modal order analysis as a dynamic basis were identified. Meanwhile, the response spectrum was analyzed to determine the dynamic response of structures under seismic action, to draw the maximum internal force of the structure of each component, and these can provide the basis for the structural design.
