【摘要】 在役场馆的建成年代各不相同,合理地确定场馆的设防标准直接关系到场馆改扩建中的安全性和经济性。讨论了在役场馆不同后续服役期的三水准设防问题后,给出了不同使用年限下场馆地震影响系数的修正值。本文不但对奥运场馆改扩建工程有实际指导意义,也对其它在役建筑物的加固有较好的适用性。更多还原

【Abstract】 A majority of gymnasium of 2008 Olympic Games will be fortified from the existing gymnasiums which building age are different. Reasonable Seismic Fortification criterion for the existing gymnasiums will decide the security and economics of the fortifying work. In this paper, three level of the fortification criterion of the existing gymnasiums in re-service term are discussed, and revised seismic influence coefficients in different using years are calculated. The result of the paper can not only be applied in fortifying the gymnasiums of 2008 Olympic Game, but be applicable of fortifying and maintaining the other existing building.更多还原
