The Analysis Of Earthquake Resistance Of Irregular High-rise Structures With Chassis

This paper introduce the state of the development of irregular high-rise structures and analyze adverse factors about the stress and displacement of irregular structures at first , meanwhile discuss the methods to process the irregular high-rise structures and the theories to calculate earthquake actions. Based on the above work, SATWE,TAT and ANSYS are used to set up an irregular structure model, analyze it together and crosscheck. And then, three groups of structure model with different height of chassis, position of center of mass and structural length in PKPM are set up. Then analyze the changes of the period, stress and displacement. At last, some meaningful points are concluded and some countermeasures for structural design are put forward.
