对抗震设计中结构体系的浅析

On Structure System in Anti- Seismic Design

概述了结构体系抗震设计中的影响因素。从强调概念设计、明确传力途径,力求强度、刚度和变形能力的统一,设置多道抗震防线,增加内外部赘余度、减少负担重力荷载的构件,避免刚度突变,控制抗震薄弱层,调控动力特性等几个方面,论述了结构体系应满足的要求。

This paper overviews the influence factors in structure system seismic design. The author discusses the requirements that the structural system should meet from aspects of emphasizing conceptual design,clearing power transmission way,striving to the unity of the strength stiffness and deformation capacity,setting multichannel seismic line,increasing the degree of internal and external outages,reducing gravity load components,avoiding stiffness mutation,controlling the seismic weak layer and regulating dynamic characteristics.
