Swing masonry wall with inwards-concave wall side ends

Abstract

The invention provides a swing masonry wall with inwards-concave wall side ends. The swing masonry wall solves the problem that a masonry wall is in an oblique section shear failure mode in earthquakes, so that anti-seismic property and post-earthquake repairing property are poor. Inwards-concave cavities which concave towards the inside of a non-hole masonry wall section are formed in the left and right of the non-hole masonry wall section and are located at elevation positions of upper edges or lower edges of any hole, the inwards-concave horizontal size of the inwards-concave cavities is smaller than or equal to one thirds of the distance between the left side and the right side of the non-hole masonry wall section, and the inwards-concave cavities are filled with flexible matter. The swing masonry wall is novel in work principle, and can effectively avoid shear failure of the masonry wall and achieve a normal section bent cracking form; ductility and energy-dissipating capacity of the masonry wall can be improved, post-earthquake repairing property is greatly enhanced, and earthquake relief work and post-earthquake repairing difficulty of engineering is reduced; construction is convenient, manufacturing cost changing amplitude is small, and the swing masonry wall is suitable for common masonry engineering facilities, especially masonry structure house building, reinforcement and reconstruction and post-earthquake reconversion of high-intensity earthquake fortification areas.

Description

technical field [0001] The invention relates to the field of anti-seismic and disaster prevention of engineering structures, in particular to a masonry anti-seismic wall in a masonry structure, in particular to a concave swinging masonry wall at the end of the wall. Background technique [0002] The solid wall section between the left and right adjacent openings on the masonry wall is a masonry non-hole wall section, its seismic shear bearing capacity is low, the shear-span ratio under earthquake action is small, and its earthquake damage form is generally a brittle oblique section Shear failure often leads to the truncation of the masonry wall at the middle, which is difficult to repair and needs to be demolished and rebuilt, which brings great difficulties to earthquake relief and post-earthquake recovery. For example, under the action of horizontal earthquake, the wall section between windows of masonry structure generally shows X-shaped cross shear cracks, which may lead...

Problems solved by technology

[0008] In order to solve the problem that the existing masonry wall is in the form of oblique section shear failure under earthquake, which leads to poor seismic performance and post-earthquake repairability, the invention provides a method that can prevent oblique section shear failure and realize normal section bending cracking. Shape, post-earthquake repairability, excellent seismic performance and convenient construction and application of the concave swinging masonry wall at the end of the wall
