【摘要】 为了研究近场强震下单斜式中心支撑钢框架(DL-CBSF)的层剪力分布,设计了5个算例结构,采用弹塑性时程分析方法获得了结构在近场罕遇、设防地震下的层剪力分布,提出了DL-CBSF结构层剪力分布模式,并分析了近场地震速度脉冲效应、地震波加速度幅值、结构层数、结构跨度、跨数对层剪力分布的影响。更多还原

【Abstract】 In order to investigate the story shear distribution of diagonal lined-CBSF under near-field earth-quakes, five DL-CBSFs were designed. The story shear distribution of DL-CBSFs under two kinds of earthquake records were obtained through the nonlinear time history method. The formula of story shear of DL-CBSF was proposed. The effects of near-field earthquake with velocity pulse, earthquake acceleration amplitude, story num-ber, structural span and span number on the story shear distribution were analyzed in this paper.更多还原
