Researches on the Structural Influencing Coefficient of Steel Frames under Different Sites Based on the Energy Concept

Abstract:

The structure influencing coefficients reflect discount rate on horizontal seismic action of different structure categories. In general, the structure influence coefficients are related with the ductility level and overstrength of the structure. According to Code for seismic design of buildings (GB50011-2008), four models of three story-steel frames are designed for 4 types of site. Dynamic time-history analysis is carried out to study the models with records of seismic waves. The ductility level, the over-strength and Structural Influencing Coefficient are derived by the energy concept in the different sites condition. Structural Influencing Coefficient based on the energy concept is a new attempt. Method of the energy concept and design of structure will become the important development direction to improve the traditional seismic design.
