2010年11月 施工技术 第39卷第11期 CONSTRUCTION TECHNOLOGY 21 延安火车站张弦梁结构隔震支座减震控制 梁建文 (中铁十二局集团西安北站工程指挥部,陕西西安710021) [摘要]将隔震支座引人张弦梁结构中,采用通用显式动力分析程序LS-DYNA软件对一实际工程的单榀张弦梁结 构进行隔震情况下和非隔震情况下地震响应分析,并分析了隔震支座水平刚度和阻尼大小对张弦梁结构的减震影 响,计算分析结果表明,隔震支座对张弦梁结构的减震效果比较明显,可有效应用于张弦梁结构的振动控制.

Key words:beam string structure;isolation;vibration reducing anal...
