| 摘 要： | 基础隔震技术在目前的结构分析和设计过程中,对于冲击性较强的近断层地震作用考虑较少,特别是对竖向分量的考虑.本文选取1999年台湾集集地震中,含有完整水平与竖向地震分量的近断层速度脉冲型记录与断层附近非脉冲型记录作为地震输入,分析了基础隔震结构在近断层水平一竖向地震分量共同作用下的动力响应以及隔震支座的受力状态.结果表明...

| Abstract: | The base-isolated technology is a generally acknowledged measure to resist the earthquake action and reduce the loss of building structure.But the near-fault seismic action,impulsive strongly,is not taken into account usually,and the vertical component is less especially.Some earthquake acceleration records selected from Chi-Chi Earthquake in Taiwan,including horizontal and vertical components,are divided into two types,near-fault pulse and non-pulse.The structural responses and the stress of base-isolated ... |
