摘　　要：借助变角桁架模型，建立受弯构件Ｔ形截面在使用荷载下的斜裂缝特征值与截面剪应力之间的相关关系，据此可推断出截面的剪力水平，为已有建筑物的受剪承载力评估提供基础。３３个试验梁的计算结果与试验值符合较好．The relations between the inclined crack character values under service loads and shear stresses of the T-shape beam sections are developed herein based on a variable angle truss model using which shear level of sections can be predicted, and the basis of assessing the shear strength of existing buildings is provided. The test results of 33 beams showed a good agreement with theoretically computer results.
