苏联钢筋混凝土科学研究所与平札建筑工程学院共同拟定了钢筋混凝士柱牛腿计算的新方法——在剪力作用下,牛腿的承载能力取决于集中着压应力的假定的倾斜带的强度(图1)。主压应力的基本方向,为传递于牛腿下的外力的合力的作用点和牛腿的底边与柱边的交点的连线(图1中的α_n)。计算的混凝土倾斜带的上部宽度取决于传递外荷载的支承面宽度l_(on),下部带宽l_p由牛腿倾斜边和裂缝上方混凝土高度x_0决定。在破坏阶段,倾斜
The Soviet Institute of Reinforced Concrete Science and the Institute of Civil Engineering in Heinzhood have jointly developed a new method for the calculation of the corbel of a reinforced concrete column. Under the action of shear forces, the load capacity of the corbel is determined by the hypothetical inclined belt concentrating on compressive stress. The intensity (Figure 1). The basic direction of the principal compressive stress is the line connecting the point of action of the resultant force of the external force transmitted under the calf leg and the intersection of the bottom edge of the bovine leg and the column edge (α_n in FIG. 1 ). The calculated upper width of the concrete inclined zone depends on the supporting surface width l_(on) of the transfer external load, and the lower bandwidth l_p is determined by the inclined height of the bovine leg and the height of the concrete above the fracture x_0. During the sabotage phase, tilt
