此文引用剪力薄层法的一项基本假定,使框架法的未知冗力大为减少——n层剪力墙的未知力由3n个减为n个.所得基本方程组可用一次传递法求解,获得满意结果.分析时,计入了墙肢的轴向变形.此法可用于实践中常见的一些情况,诸如不规则分布的水平荷载,以及有一定变化的楼层高度、墙肢厚度和联系梁刚度.文末,以顶层联系梁为例,讨论了局部刚度的变化对内力所引起的影响.在计算过程中,曾与剪力薄层法的计算结果进行了核对.二者吻合良好.
This paper cites a basic assumption of the shear thin layer method, which greatly reduces the unknown framing force of the frame method. The unknown force of the n-story shear wall is reduced from 3n to n. The resulting basic system of equations can be used for one pass method. Solve to obtain satisfactory results. When analyzing, account for the axial deformation of the wall limbs. This method can be used in some common situations in practice, such as irregularly distributed horizontal loads, as well as certain changes in floor height, wall thickness, and Contacting the beam stiffness. At the end of the paper, using the top-level contact beam as an example, the influence of the local stiffness change on the internal force is discussed. In the calculation process, the calculation results of the shear thin layer method have been checked. The two are in good agreement.
