徐金1， 和美美2(1中國民航大學機場學院，天津300300; 2河北工業(yè)大學土木學院，天津300130)[摘要] 在考慮地震動豎向扭轉(zhuǎn)分量的情況下，對單向偏心的框架結(jié)構(gòu)進行彈塑性地震反應分析，比較分析四種偏心率的單向偏心框架結(jié)構(gòu)在多維地震動作用下的扭轉(zhuǎn)反應，進而得到關(guān)于結(jié)構(gòu)扭轉(zhuǎn)效應的動力特征和規(guī)律。[關(guān)鍵詞] 地震；單向偏心；扭轉(zhuǎn)反應中圖分類號：TU375 文獻標識碼：A 文章編號：1002-848X(2012) S2-0325-03Torsional response analysis of unidirectional eccentric structures under seismic actionsXu Jin1, He Meimei2(1 Civil Aviation University of China, Tianjin 300300, China; 2 Hebei University of Technology, Tianjin 300130, China)Abstract: Considering seismic vertical torsion component case, elastic plastic seismic response analysis of the unidirectional eccentric frame structure was done. Torsional responses of four eccentricity unilateral eccentric frame structures under the multi-dimensional seismic were compared. And then the dynamic characteristics and laws of torsion effect about the structure were got.Keywords: seismic; unidirectional eccentric, torsion reaction
