An optimal design method for the collapse resistance of reinforced concrete shear wall structures

Abstract

The invention relates to an anti-collapse optimization design method of a reinforced concrete shear wall structure, and belongs to the field of the disaster prevention and the vibration attenuation of a building structure. The method comprises the following steps of: firstly, according to an existing condition, carrying out the initial design of the structure; according to a current design code, through a preliminary structure design and shear wall arrangement situation, determining one or a plurality of possible structure weak positions, such as shear wall corners and the like, under an accidental event or an extreme disaster, introducing component damage and destruction; and adopting a finite element method to independently carry out elastic deformation checking calculation under the function of frequent-intensity earthquakes and elastoplasticity collapse analysis under the function of rare-intensity earthquakes on a shear wall structure model, returning to the above steps if collapse happens, and constantly carrying out cyclical adjustment on a structure design according to bearing capacity requirements until the design is optimal. By use of the design method disclosed by the invention, from an integral structure system, a process is simple, and working efficiency is high. A reference method and a solution are especially provided for the collapse caused by the damage and the destruction of an important component position structure, and have universal applicability.

Description

technical field [0001] The invention relates to an anti-collapse optimization design method of a reinforced concrete shear wall structure, which belongs to the field of anti-vibration and disaster reduction of structural engineering. Background technique [0002] With the development of social production and the advancement of science and technology, the building system continues to develop, the number of high-rise buildings continues to increase, and its architectural structure forms are becoming increasingly diverse. The structural forms of high-rise buildings mainly include frame structure, shear wall structure, frame-shear wall structure, cylinder structure, slab-column-shear wall structure, etc. Among them, the shear wall structure has become the main structural form in residential and hotel buildings due to its strong integrity, large lateral rigidity, good lateral force resistance, effective resistance to wind loads and earthquake loads, and convenient construction. ...
