摘要

为验证按我国抗震规范设计的钢结构建筑的用钢量与国外相比是否偏高,本文对中美两国抗震规范的抗震设防目标、地震作用计算方法、构件截面抗震验算等方面进行了详细的比较和分析;在此基础上,分别运用中美两国抗震规范理论,计算并比较了一个20层中心支撑钢框架结构算例在软弱和坚硬两种场地条件下的水平地震作用和构件截面抗震验算结果。根据计算结果得出:我国抗震规范与美国抗震规范的抗震计算理论各有特色,依据我国抗震规范设计的钢结构建筑用钢量并不大于美国抗震规范的设计用钢量。
In order to compare the steel sum of steel structure which designed in Chinese code and American code,the seismic target,the method of calculating earthquake action,and the result of seismic calculation of cross section are analyzed in details.Based on these analysis,a steel frame structure of 20 floors is calculated separately in Chinese code and American code to compare the earthquake action and the result of seismic calculation of component cross section on condition of soft and hard soils.The result shows that Chinese code and American code has each feature,the steel sum of steel structure which designed in Chinese code is not larger than American code.
