| 摘 要： | 传统考虑后期使用年限的地震动参数研究,在建筑物抗震设计中的应用,缺乏地震危险性分析和建筑物损伤指数分析,应用性差。提出新的地震动参数在建筑物抗震设计中的应用方法,以地震危险性分析为基础,通过水平地震动加速度衰减关系方程,求得建筑场地水平向基岩峰值加速度和反应谱,以此得到地震动加速度反应谱方程,利用该方程获得地震动反应谱参数,采用变形和线性组合构建损伤指数模型,获取地震波作用下地震动参数对建筑物损伤程度。实验结果表明,利用所提方法得到的地震动反应谱最小误差为0.563,小于允许误差4.0;在50年超越概率63%的条件下地震动参数值分别为0.26、0.095,所提方法可在规定误差范围内得到地震动反应谱参数值,其进行建筑物抗震设计精度和应用性高。

| Abstract: | In the application of seismic design in buildings,the traditional study of ground motion parameters considers the period of service with lack of seismic hazard analysis,damage index analysis of buildings,and poor application.Based on seismic hazard analysis,this paper proposes a new method for the application of ground motion parameters in seismic design of buildings.Based on the relationship equation of horizontal ground motion acceleration attenuation,the peak acceleration,response spectrum of the building site and the ground motion acceleration response spectrum equation are obtained.By using the equation,the damage index model is constructed,and by using the deformation and linear combination,the damage degree of the ground motion parameter under seismic wave is obtained.The experimental results show that the minimum error of the response spectrum is 0.563,which is less than the allowable error of 4.0.The numerical values of ground motion parameter are 0.26 and 0.095 under the condition that the probability exceeds 63%in 50 years.The proposed method can obtain the ground motion response parameter value within the specified error range,and its seismic design accuracy and application are high. |
