摘　　要：通过 4榀墙梁 (有地震损伤或无地震损伤 )承载性能试验结果 ,探讨了地震损伤后墙梁承载性能的变化规律 ,研究了地震损伤造成的剪切裂缝对简支整体墙梁和中间开门洞墙梁刚度、强度及破坏机理的影响 。The paper analyses the test results of 4 wall-beams with shear cracks and without shear cracks. The damage caused by earthquake on to shear cracks in the deformation behavior, stress distribution, bearing capacity and failure mechanism of wall-beam are studied. Based on the experimental study, a design method of wall-beam in seismic asea is given.

关 键 词：墙梁 地震损伤 承载性能 破坏机理
