A multifunctional anti-buckling energy-dissipating composite wall and its installation method

Abstract

The invention provides a multifunctional buckling-preventive energy-consuming combined wall and a mounting method. The combined wall comprises an outer frame, triangular filling plates, trapezoid short box iron, steel sleeves, dog-bone type core boards, an octagonal filling plate and an outer steel plate. The outer frame is composed of two frame beams in up-down arrangement and two frame columns in left-right arrangement. Grooves are formed in oblique edges of the triangular filling plates. A plurality of protrusion blocks are arranged on each of two side walls of each steel sleeve. Grooves are formed in the edges of the octagonal filling plate. During specific mounting, the trapezoid short box iron is welded, the triangular filling plates and the steel sleeves of the lower left portion and the lower right portion are mounted, and the octagonal filling plate, the steel sleeves of the upper left portion and the upper right portion, the triangular filling plates of the upper left portion and the upper right portion and the dog-bone type core boards are mounted respectively, and finally, the outer steel plate is mounted fixedly. The multifunctional buckling-preventive energy-consuming combined wall has the advantages of full energy-consuming hysteretic curve, buckling prevention, high ductility, low weight, good convenience in processing, low cost and the like. According to the mounting method, the combined wall is constructed from bottom to top, so that the mounting method is simple, convenient and easy to operate.

Description

technical field [0001] The invention belongs to the field of anti-seismic technology of civil engineering structures, and in particular relates to a multifunctional anti-buckling energy-dissipating composite wall and an installation method. Background technique [0002] The traditional seismic design uses the damage and destruction of structural components to achieve the purpose of consuming the input energy of the earthquake, which generally causes excessive deformation or even collapse of the building structure. Energy dissipation and shock absorption absorb and dissipate the seismic energy input into the structure by setting up energy dissipation devices, so that the development of shock absorption technology is transformed from the traditional design concept of "conquering rigidity with rigidity" to the scientific design concept of "conquering rigidity with softness".

Problems solved by technology

[0003] As a new type of lateral force-resisting member, the steel plate shear wall is more and more favored by scholars at home and abroad because of its flexible structure, reliable function, and high degree of industrialization. buckling with loud noise

Although the traditional buckling-resistant steel plate wall has good energy dissipation capacity, high stiffness and shear bearing capacity, it is heavy, expensive, waste of materials, and has a single function. At the same time, the excessive stiffness makes the steel frame fail before the steel plate wall , which are not allowed by the principle of earthquake fortification

Using prefabricated concrete cover slabs as restraining members of energy-dissipating steel plates has many inconveniences in the process of manufacture, transportation and construction, and it is not easy to install on site
