| 摘 要： | 对两个缩比为十五分之一的三层、双跨、两开间的钢筋混凝土框架模型进行了振动台试验，一个模型模拟质量中心与刚度中心不一致的偏心结构，另一个模型模拟承受双向地面运动的结构。研究了结构的空间非弹性地震反应。计算结果表明，理论分析与实测结果有较好的吻合性。

| Abstract: | The dynamic experiments of models were carried out on shaking table. The dimensions of two test models with three stories, two spans and two bays, were in one fifteenth scale of the prototype structure. The first test model was designed as structural system having plane eccentricities by noncoincidence of centers of mass and stiffness. In order to study the inelastic response of reinforced concrete frame under hi -- directional ground motion,the second test model was under an earthquake simulation with a diagonal direction of base excitaton. The analysis of earthquake response was performed. It is indicated that the experiments and analytical results in the elastic and inelastic stages are in good agreement. |
