梁端支座处的应力图形状态和最大应力值与梁的支承方式,支座长度、砌体和梁的刚度、荷载性质及大小有关。本文拟运用弹性理论来解决悬臂梁端砌体的应力分布问题,并求出最大应力值不超过砌体局部抗压强度。同时为了计算方便,保持砌体边缘最大应力值不变,近似地用直线图形代替曲线应力图形并运用砌体当量层概念和应力影响线方法以求最大应力值和确定垫块尺寸。
The stress pattern state and the maximum stress value at the beam end support are related to the support method of the beam, the length of the support, the stiffness of the masonry and the beam, and the nature and size of the load. This paper intends to use the elastic theory to solve the stress distribution problem of the masonry beam at the end of the cantilever beam, and find that the maximum stress value does not exceed the local compressive strength of the masonry. At the same time, in order to calculate conveniently, keep the maximum stress value at the edge of the masonry unchanged, approximately replace the curve stress graph with a straight line figure and use the concept of masonary equivalent layer and stress influence line method to find the maximum stress value and determine the size of the spacer.
