| 摘 要： | 选择了集集地震中三条含有大脉冲的脉冲型近场地震记录，并截取其加速度峰值所在的脉冲及相邻两个脉冲部分形成新的记录，将其作为地震输入，对两个完全相同的钢筋混凝土模型进行振动台台模拟试验，对试验结果进行了分析，比较两个模型的宏观破坏、模态、顶层位移，得出近场脉冲型地震动会引起钢筋混凝土结构严重的破坏，截取的主震脉冲时程对结构的影响效应在一定程度上完全可以等同于整幅地震动时程。

| Abstract: | Selected three records of near-field pulse-type ground motion in Chi-chi earthquake, and the part of dominant pulse of PGA and its adjacent pulses are taken as new record, then the new record is used as the input for shaking-table tests of two same one floor single bay RC structural models respectively. The test results of the two models show that their the damage, modal and displacement are similar, So the conclusions are obtained that the near-field pulse-type ground motion cause serious damage to RC structures, and the effect of both full time history and dominant pulse time history on RC frame models is same in some way. |
