21.梁端支承处砌体局部受压承载力的验算梁端支承处砌体的局部受压是砌体结构最主要的一种情况。一般说来,其支座处压力分布是与梁的刚度和支座构造密切有关的。图4所示为三种情况的支座压力分布图。图4a适用于墙梁和上部砌体高度较大的过梁下的应力分布,由于梁和砌体共同 21. Checking the local compression bearing capacity of the masonry at the beam end bearing The local compression of the masonry at the beam end bearing is the most important condition of the masonry structure. In general, the pressure distribution at the support is closely related to the stiffness of the beam and the support structure. Figure 4 shows the bearing pressure distributions for the three cases. Fig. 4a applies to the stress distribution under wall beams and lintels with large upper masonry heights, due to the joints between beams and masonry
