【摘要】 本文依据我国建筑抗震设计规范对基于性能设计方法的相关规定,主要针对性能水准3和4设计方法在实际操作中的困难,提出了一种直接提高设防烈度或抗震构造措施的简便等代设计方法;并通过多层钢筋混凝土框架结构算例的非线性分析,从结构楼层位移、楼层剪力和层间位移角等方面对比分析了结构在不同地震水准下的抗震性能,验证了该方法对于保证多层规则钢筋混凝土框架结构抗震性能的有效性。更多还原

【Abstract】 According to requirements about performance-based design in current China Seismic Design Code and some inconvenient of performance level 3 and 4,an approach is proposed in the paper which increasing designed intensity or seismic design details to meet performance targets of buildings. Meanwhile,multi-story RC moment frames are designed using both code method and the approach,and nonlinear dynamic analysis are carried out. The seismic behavior of frames designed using the approach are compare with ones using code method,and the efficiency of the proposed method is verified by the comparison of analysis results under different earthquake input such as story displacement,shear force and drift angle etc.更多还原
