【提要】詳細分析了蘇州國際博覽中心標(biāo)準(zhǔn)展廳結(jié)構(gòu)在地震作用下的反應(yīng),對在兩個主軸方向抗側(cè)剛度相差較大的結(jié)構(gòu)在地震作用下的反應(yīng)及與扭轉(zhuǎn)效應(yīng)的關(guān)系進行了分析,指出使結(jié)構(gòu)主振周期避開場地特征周期是減小結(jié)構(gòu)地震反應(yīng)的有效途徑,兩個主軸方向抗側(cè)剛度有一定差別有利于在經(jīng)濟的前提下減小扭轉(zhuǎn)效應(yīng)。

Seismic Reaction Analysis of Suzhou Expo Center Standard Exhibition Hall/ZhaoHongkang,Dai Yaping (Suzhou Institute of Architecture Design Co., Ltd., Suzhou 215002,China)
Abstract:Seismic reaction of the Suzhou expo center standard exhibition hall is analyzed and the seismic reaction on the structure whose stiffnesses are different in two directions and the relationship between the stiffness ratio of the directions and torsion reaction is diccussed. An efficient method to reduce the seismic reaction and avoid the character
istic period of the site is pointed out and the difference between the stiffness on t
wo directions redounds to reduce the torsion reaction economically.
