摘要
轻钢增层的刚度突变已引起工程界的关注,在轻钢增层结构的抗震设计中,采用的是新建部分和原有部分分别满足抗震要求的设计方法,与相关规范中的整体抗震要求相冲突。阐述了刚度及轻钢增层中相关技术问题,论述了轻钢增层结构刚度突变与相关规范相冲突的部分,得出了几点结论,为轻钢增层的应用提供借鉴。
The problem of Stiffness mutation of light-steel added storeys has aroused concern among engineering community.In the antiseismic design of light-steel added storeys,the method of meeting the antiseismic needs of new-constructed and original part respectively is adopted,which is collide with the demand of seismic resistance.This paper states some relevant technique problems of stiffness and added storeys of lightweight steel and discusses the sections of stiffness mutation of light-steel construction that violate correlate standards.Then it draws conclusions that can provide reference for the application of added storeys made of light steel.
