摘要
介绍了印度规范和美国规范地震参数转化方法,以水泥生产线余热发电项目水泵房框架结构为例,对比了印度规范IS 1893(Part 4):2005和美国规范ASCE/SEI 7-10中的结构重要性系数、场地分类、反应谱修正系数、最大地震反应谱加速度系数等重要地震参数的转换,并结合工程项目实例,比较了印度规范和美国规范的地震反应谱曲线拟合程度和水平地震力计算结果,验证了地震参数转化的正确性。地震参数转化结果表明,印度规范和美国规范的地震反应谱曲线基本拟合,水平地震力计算值基本相近。
The method of transformation seismic parameters between Indian standard and American standard was introduced.Taking the structure design of the pump house in waste heat recovery power project for cement factory as an example,through the contrastive analysis of the important seismic parameters such as importance factor,site class,response modification coefficient,maximum earthquake spectral response acceleration parameters,etc.between the Indian standard IS 1893(Part 4):2005 and American standard ASCE/SEI 7-10.The correctness of the parameter transformation was verified by the seismic response spectrum curves fitting and the calculation results of the horizontal earthquake.The results of transformation seismic parameters showed that the seismic response spectrum curves of the Indian and American standard were fitted,and the calculated horizontal seismic forces were close.
