摘　　要：基于国内外现行的结构抗震安全评估体系,使用静力弹塑性方法针对不规则结构进行了分析与研究。通过3个不同层高的钢筋混凝土不规则结构算例,分析了在不同侧向荷载分布下,结构的顶点位移与基底剪力的关系以及层间位移的计算精度问题,并对其进行了讨论。通过对加载模式进行适当的改进,使计算误差减小,为科学研究的进行和工程实际的应用提供参考。Based on the domestic and international seismic evaluation methods, the static Elastic-plastic method is used to analyze the seismic behavior of irregular structure in this paper. By analyzing three different floors irregular reinforced concrete structures which bear different distributions of lateral load, the relationship between top displacement and base shear, and calculation accuracy of storey drift are obtained. Through improving the mode of distributions of lateral load, the calculation errors are reduced, and the reference can be provides for the scientific research and the applications of practical projects.
