Wedge-shaped section combined shear resistance design method and device

The invention relates to a wedge-shaped section combined shear resistance design method and device, and the method comprises the following steps: constructing the weakest wedge-shaped section of any position of a component, and enabling the cracking surface of the weakest wedge-shaped section to be perpendicular to the pressure-bearing surface; calculating the upper limit of the horizontal projection length of the weakest wedge-shaped section, and judging the upper limit of section shear calculation; calculating the weakest wedge-shaped section shear bearing capacity according to a section shear calculation upper limit judgment result; and carrying out anti-shearing design judgment based on the weakest anti-shearing bearing capacity of the wedge-shaped section. Compared with the prior art, the method has the advantages of being high in scientificity, accurate in calculation and the like. 本发明涉及一种锲形截面组合抗剪设计方法及装置，其中方法包括以下步骤：构造构件任一位置的最薄弱锲形截面，所述最薄弱锲形截面的开裂面与承压面相互垂直；计算最薄弱锲形截面水平投影长度上限，进行截面抗剪计算上限判断；根据截面抗剪计算上限判断结果，计算最薄
