摘　　要：研究砖混结构房屋阳台荷载通过挑梁传播到房屋的横墙和纵墙上的分配情况.采用14节点56自由度高阶有限元程序SDSAP,提出和讨论了几种计算模型,用集中荷载和力矩代表房屋阳台荷载(包括阳台自重、板、栏板及活荷载)进行了大量的数值分析,最后归纳出房屋横墙和纵墙各自承受阳台荷载的分担比例.这一结果对房屋墙体强度和基础宽度的计算与设计具有重要的参考价值.Propagation principle of the balcony loading onto the cross and vertical wall in masonry structure were studied. A few computational models for the propagation of the balcony loads （including weight of railing and floor and active loading） were presented and analyzed herein by a FEM program, adopting a 14-noded rectangular element of 56 degree freedom. Concentrated forces and couples are chosen to represent loading of balcony. Extensive computations of the model were carried out and it finally led to the determination of axial force of both cross and vertical wall of the masonry structure house. The consequence of the analysis is of significant referential value to the calculation and design of base of the masonry houses.
