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.
