The Influence of Seismic Motion Input Direction and Damping on the Dynamic Analysis of Mega Steel-Frame Structure

Abstract:

A more accurate simulation of the response to the structure under seismic load action can be generated through taking bi-directional seismic motion input into consideration. The commonly used four calculation methods of bi-directional input are adopted in this paper to compare the different dynamic responses of mega steel-frame structure to seismic load action. The paper also provides a method for choosing Raleigh damping coefficients applicable to the dynamic analysis of mega steel-frame structure.
