【摘要】 文章回顾了我国抗震设计规范的演变过程,将时程分析法与底部剪力法和振型分解反应谱法进行了对比,指出了时程分析法在抗震设计计算中的地位与作用,时程分析法是能够考虑地震动三要素、地震环境、结构的非线性和能量损耗及损伤的真正动力分析方法,是比底部剪力法和振型分解反应谱法更精确、更可靠、更合理的方法,不应仅仅作为补充计算的方法,而是也应作为结构抗震设计的基本方法,望在今后的抗震设计规范修订中予以斟酌、考虑。更多还原

【Abstract】 The evolution process of seismic code is reviewed.The comparison among the time-history analysis,the bottom shearing,modal response spectrum methods are made in this paper.The status and role of these methods are discussed.We think that the time-history analysis is a better method of analysis and it is not only a complete calculating method but also a basic method.更多还原
