摘要
轻钢增层结构属于复合结构,我国建筑抗震规范尚未对复合结构的抗震设计方法作出具体规定,传统的抗震设计方法偏于不安全。本文提出了轻钢增层结构的实模态强振型解耦法,并对现行规范的地震影响系数提出了修订意见。
A structure raised by some light-gauge steel storeys is a compound structure. Jn seismic code for buildings in China, the seismic computing method for compound structure is not proposed, and traditional seismic design method is unsafe. A real mode-decoupling method for the structure with raised light-gauge steel storeys and a revision for influence coefficient in the seismic code for buildings in China are presented.
