【摘要】 在对《建筑抗震设计规范(GB50011-2001)》和《建筑工程抗震性态设计通则(试用,CECS 160:2004)》研究的基础上,根据广东地区的场地和地震作用特点,确定出了广东省甲、乙、丙类建筑不同设防水准的地震动峰值加速度,以及广东省91个城镇的特征周期分区值,为广东省建筑物抗震设计提供了更加可靠的地震动参数。更多还原

【Abstract】 Through analyses on Code for Seismic Design of Buildings(GB50011-2001) and General Rules for Performance Based Seismic Design of Buildings(Tentative standard,CECS 160:2004),peak ground accelerations corresponding to different seismic fortification levels of the three classes of building and zoning values of characteristic periods of 91 major towns of Guangdong Province are determined according to characteristics of sites and earthquake actions of Guangdong region.Our results provide more reliable ground motion parameters for seismic design of buildings of Guangdong Province.更多还原
