学习剪力墙（Study of shear wall） shear wall Because of the larger size of the door and window, the normal stress on the cross section of the shear wall is no longer in a linear distribution, and the force and deformation of the double wall joint wall occur The linear stiffness of the wall member is much larger than that of the coupling beam, and there is an anti bending point at the middle of each coupling beam, and the bending effect of each wall limb is remarkable, It is only in a few layers that there is an anti bending point on the wall, so it needs to be analyzed by the corresponding method. A wall with a row of openings on the wall is called a double limb wall Multi row hole, Chengduo shear wall. Because of the connection of the connection beam, the double limb wall becomes a high degree of super static when analyzing the internal force of the double limb wall Fixed problem. In order to simplify the calculation, the general differential equation method (continuous link method) can be used to calculate. (1) basic assumption a) the connecting beam at each floor is reduced to a uniformly continuous link; (b) neglecting the axial deformation of the coupling beam, i.e., assuming that the two walls are equal to the horizontal displacement at the same height; (c) assume that the rotation and curvature of the two walls at the same height are equal, i.e., the deformation curve is the same; (d) assume that the anti bending points of the connecting beams are at the midpoint of the connecting beam; F) to think, moment of inertia, double layer shear wall; cross-sectional area, link beam; cross sectional area and moment of inertia parameters along the wall height direction is constant. The shear wall structure is a series of vertical, transverse shear walls and floor structure, which is subjected to vertical and horizontal loads, and is a high-rise building Structural forms in common use. Because the stiffness of the longitudinal and transverse shear walls in their plane is very
