摘要

针对工程场地地震安全性评价中,确定钢结构构筑物抗震设防参数存在不同阻尼比的情况,以江苏省大丰市某钢结构构筑物的抗震设防参数为研究对象。首先,采用一维等效线性化波动分析方法进行地震动效应分析计算后,对计算反应谱进行规准,得到不同阻尼比、不同概率水准的规准谱参数;其次,根据当前的规范可以推算得到相应的地震动参数;最后,考虑规准谱参数与相关规范的衔接,通过综合比较分析,给出满足工程抗震设防要求的设计地震动参数,为重大建设工程的抗震设计提供依据。
For the evaluation of seismic safety for engineering sites to determine the steel structure construction parameters of seismic fortification of their different damping ratios,in Dafeng City,Jiangsu Province,a steel structure building's anti—seismic fortification parameters as the research object.The ground motion effect analysis is performed by using the one—dimensional equivalent linearization wave analysis method.Firstly,based on the normalization of calculated response spectrum,the normalization response spectrum parameters with different damping ration and different probabilities of exceedance are gauged.Secondly,according to the current codes for seismic design,the corresponding seismic ground motion parameters can be reckoned.Finally,consider the connection between normalization spectrum parameters and relevant specifications,through a comprehensive comparative analysis is given to satisfy the engineering requirements for seismic resistance design of motion parameters,provide the basis for the seismic design of the major construction projects.
