摘　　要：以框支密肋复合墙梁为研究对象,通过有限元分析,改变上部密肋复合墙板的划分形式、边框柱尺寸以及填充砌块与密肋框格的弹性模量比等性能参数,研究竖向荷载作用下框支密肋托墙梁的受力机理及墙板参数对托梁受力的影响,进而对框支密肋复合墙梁的优化设计提出要求,为工程实践提供参考。FEM was employed to study frame-supported multi-ribbed wall beam under vertical load. Using the changes in performance parameters such as divided form of wall, the size of the side column and the ratio of in-filled block and multi-ribbed frame, the mechanism of frame-supported multi-ribbed wall beam and the influencing factors of the parameters of wall to the wall beam are studied. Which provides references for the optimization and engineering practice of frame-supported multi-ribbed wall.
