摘　　要：以3层外肋板式联肢组合钢板剪力墙-钢连梁结构为研究对象,利用ABAQUS软件建立有限元模型并分析.分别研究不同钢材屈服强度和钢连梁变形特征下,外肋板宽厚比对结构抗震性能的影响,以确定外肋板最优尺寸.研究结果表明:当采用Q235钢时,外肋板宽厚比应取12左右;当采用Q345钢时,取值范围为8~12;当采用Q390钢时,取值范围为4~12.钢连梁变形特征对外肋板宽厚比的取值影响较小,最佳取值为12,但弯剪型和弯曲型的结构所需外肋板尺寸较剪切型更大.A three-storey external ribbed plate combined steel plate shear wall-steel link beam structure was taken as the research object,and the finite element model was established and analyzed by ABAQUS software.Under defferent yield strength of steel and deformation characteristics of steel coupling beam,the influence of the width-thickness ratio of external rib on the seismic performance of the structure was investigated to determine the optimum size of the external ribbed plate.The results show that when Q235 steel is used,the width-thickness ratio of the external rib plate should be taken as about 12;when Q345 steel is used,the value range is 8-12;and when Q390 steel is used,the value range is 4-12.The deformation characteristics of the steel link beam have less influence on the value of the width-thickness ratio of the outer ribs,and the best value is 12.However,the shear and bend type structures require a larger external rib size than that of the shear type.
