美标IBC和UBC地震参数与国标抗震设防烈度对应关系探讨

该文通过对IBC地震参数Ss、S1、PGA,UBC地震分区系数,GB设防烈度及各规范相应场地类别进行分析探讨,将IBC和UBC地震计算参数和分区系数与GB规定的有效峰值加速度及抗震设防烈度进行对比分析,找到其对应关系,以便在海外工程前期项目中能根据标书采用的美标参数快速确定相应的GB抗震设防烈度,为项目工程量及概算造价提供依据。

In this paper,the IBC seismic parameters Ss,S1,PGA,UBC seismic par tition coef f icient,Seismic precautionary intensity and the corresponding site categories of each standard are discussed.The seismic calculation parameters of IBC and the seismic partition coeff icient of UBC are compared with effective peak acceleration and seismic precautionary intensity of GB.Then found the corresponding relationship,so that the corresponding seismic precautionary intensity can be quickly determined according to the American standard parameters adopted by the tender in the overseas project,which provides the basis for the project quantity calculating of building materials and the estimated cost.
