摘要
通过１５层钢筋混凝土异型柱斜撑框架结构模型的模拟地震振动台试验，研究了斜撑框架结构的自振特性、地震反应时程及频谱特征，并采用空间结构有限元分析程序进行了建模研究和理论计算．计算模型采用空间梁单元与空间板单元，材料特性取实测值．通过模态计算得到结构各阶自振特性值，利用直接积分法计算结构的动力反应．由数值的分析可知，理论计算与试验结果一致．
In this paper, by means of shaking table test study on 15-floors reinforced concrete frame model with hetero-columns and diagonal braces, the natural vibration property, history process and frequency-spectrum feature of earthquake action are analysed. A reasonable caculation model of this structure is built and theoretical caculation is accomplished through a spatial finite element program. A conclusion that the caculated results are consistent with the experimental result is reached.
