摘　　要：给出 8个框支墙梁在水平低周反复荷载作用下的试验结果 ,讨论其受力性能和破坏形态、变形性能和滞回延性、抗震性能与组合作用。在试验基础上提出墙梁墙体受剪承载力公式 ,通过有限元分析给出框支墙梁托梁和框支柱内力和承载力计算公式 ,均与试验符合良好。基于试验研究和有限元分析 ,提出框支墙梁抗震设计建议。.The test results on 8 specimens of the wall beams supported on frame are given.The behaviour and modes of failure,the deformation and hysteresis loop,the composite action and earthquake resistance are discussed.The formulas of horizontal shear capacity for the walls of wall beams supported on frame based upon the test results,and the formulas of inner forces and the calculation of bearing capacity for the bressummer and frame column by means of the finite element analyses are presented respectively.The results of calculation tally well with the test results.The suggestions for aseismic design of the wall beams supported on frame are presented.
