摘　　要：对混合结构的Ｔ形截面承重纵墙进行非线性全过程分析，计算简图是由钢筋混凝土梁和Ｔ形截面砖砌体墙段构成的组合平面框架，采用实际刚性法的杆系模型。通过对梁跨为１２ｍ的五层楼房计算，表明墙体的约束弯矩与上部压力及梁的上部钢筋面积紧密相关，墙体的内力重分布在整个加载过程不断进行。A non Linear full range analysis of bearing masonry longitudinal wall has been carried out in this paper.A combination plane frame composed of R.C.beams and T section brick masonry columns is chosen as computational diagram.Bar system model with actural rigidity method is employed.According to analysis of 5 storey building with 12 meters span,the analysed results show the restraining moments of the beam are closely related with upper compressive force and the area of the upper side reinforcement of the beams.The redistribution of the internal forces of the wall is existed within the whole loading range.
