ラーメン構造の弾塑性耐震解析に関する研究

Abstract

Elastic and elastio-plastic earthquake-resistant analysis of frame construction is mainly studied in this paper. In elastic stage, response and vibrated characteristics of symmetrical and unsymmetrical structure are investigated by comparing the results of plane and space analysis. The effect of approaching angle of seismic wave to vibrated characteristics of structure under different column/beam rate are discussed. In elastio-plastic stage, four kinds of plastic mode with different plastic positions are established, the response displacement and hysteresis curves are compared at different plastic modes, the plastic extension at specified and unspecified plastic position are compared too, the effect of plastic modes to the analysis results is discussed finally.
