摘要
本文用空间的两向抗侧力体系振动模型对五层剪切结构分别分析了首层偏心、中间层偏心顶层偏心和均匀偏心等不同偏心情况下的弹性地震反应规律,研究了静力偏心距、结构的基本平动周期、平扭频率比、非激励方向的平动频率等对结构的名义基底剪力和偏心层构件的最大剪力系数的影响.
Using the orthogonal lateral resistant dynamic model, this paper analyzed the elasticearthquake response of asymmetric multistorey buildings with different eccentric conditions suchas first storey, middle storey, top storey, or all storeys are asymmetrical, respectively. The effectsof eccentric ratio, fundamental lateral frequency, the frequency ratio of lateral to torsional, andlateral frequency of orthogonal direction on the structure's nominal base shear and maximumshear coefficient in eccentric storey are researched.
