Numerical Simulation on the Overall Dynamic Response of One High-Rise Steel Frame

Abstract:

Using the finite element analysis software ANSYS to analyze the overall dynamic response of one specific high-rise steel-frame,including modal analysis, spectrum analysis and time-history analysis. Then do a comparative analysis with the results of calculation by the professional software PKPM. As the results: the structural calculation can use layer model; Larger mutations appeared in the stress of weak-story and the relevant story need to reinforce or set up supports under the anti-seismic design in the elastic time-history analysis of structure; Y-direction translation is preferentially happened in first order modal shape and lateral-torsional coupling happened in third order modal shape among the vibration mode analysis; The response spectrum analysis of frequent earthquake show that seismic action is more serious in ground layer.
