摘　　要：本研究先建立简化的掉层建筑模型做力学分析,再通过基本模型比较精确解与有限元解的差别,并分析基于单位边坡水平变形下,简化模型在掉层层高、掉层层数、梁跨度、上接地层层高等维度变化的力学行为,初步找出结构薄弱部位;最后通过对某工程的抗震性能化设计采取计算并分析,结果表明边坡变形、掉层跨数布置、二阶效应等对该类建筑结构影响甚大,所得结果对类似掉层山地建筑的结构设计具有借鉴意义。In this paper,a simplified model of drop-off building is established for mechanical analysis,and then a basic model is used to compare the difference between the exact solution and the finite element solution.The mechanical behavior of the model is simplified in the dimension of the height of the dropped layer,the number of the dropped layer,the span of the beam and the height of the upper ground layer in the end.Through the calculation and analysis of the seismic performance-based design of a project,the results show that the slope deformation,the number of floor-falling span arrangement,the second-order effect and so on have great influence on this kind of building structure,the results are useful for structural design of similar buildings in mountain areas.
