First of all, the paper carried out test study on four two-spanned model members of FSMRCWB, including three 1/2-scaled two-storeyed models and one 1/3-scaled three-storeyed model. The paper analyzed the test results, including analysis on mechanical property of the composite wall beam under vertical loads, and failure mode, deformation capacity, aseismic performance under horizontal loads and constant vertical loads. Secondly, the nonlinear property of concrete is studed and the nonlinear models of FSMRCSS is builded by ANSYS. Last, The paper studies the result of ANSYS, which mainly includes the loading-displace curve of FSMRCSS under horizontal loads and constant vertical loads, the mechanics of arch under vertical loads lonely and under horizontal loads and constant vertical loads respectively, and status of the distribution and changing of vertical stress and cross shear on the surface of the suporting beam, and the influence of span ratio and hole.All in all, the caculating results are in good agreement with the test results.

本文首先进行了三个1/2比例的两跨两层和一个1/3比例的两跨三层的框支密肋复合墙梁的模型试验，分析了框支密肋复合墙梁在竖向荷载作用下的受力性能，以及在竖向荷载与水平低周反复荷载共同作用下的受力性能、变形性能、滞回性能、耗能系数及破坏形态；其次，研究了混凝土的非线性特性，建立了框支密肋复合墙梁非线性有限元模型，并借助大型通用有限元软件ANSYS进行计算；再则，进行了非线性有限元结果分析，主要研究框支密肋复合墙梁在竖向荷载与水平地震力共同作用下的荷载位移曲线，分析在竖向荷载单独作用下和在竖向荷载与水平地震力共同作用下墙梁的拱作用，托梁顶面的竖向应力和横向剪应力分布及变化情况，并讨论跨度比、洞口对墙梁拱作用和托梁顶面的竖向应力的影响。
