Abstract

The invention relates to a method for determining bearing capacity of a concrete-filled steel tube under various stressing conditions, which is characterized by solving the technical problems that the bearing capacity of the concrete-filled steel tube under various stressing conditions can not be determined simply, conveniently and directly, and providing a safety evaluation method of a concrete-filled steel tubular member under the complex loading combination of pressure, bending moment, shearing force and torsion moment. The concrete-filled steel tube is under the action of pressure, bending moment, shearing force and torsion moment, and the safety evaluation method comprises the following steps of: collecting the relative parameters of the concrete-filled steel tube; collecting the compressive strength design valves of steel and concrete in the concrete-filled steel tube, and collecting the cross sections of the steel tube and the concrete in the concrete-filled steel tube; and determining the bearing capacity of the concrete-filled steel tube: the bearing capacity of the concrete-filled steel tube under the action of pressure, bending moment, shearing force and torsion moment meets the equation shown in the specification.

Description

technical field [0001] The invention relates to a method for determining the bearing capacity of steel tube concrete and its application, in particular to a method for determining the bearing capacity of steel tube concrete under various stress conditions and its application. Background technique [0002] With the continuous increase of building span and the improvement of building non-seismic requirements, the research on the shear and torsional performance of structures is very important. Moreover, in the actual structure, the concrete filled steel tube is in the state of compression, compression, bending, and even compression, bending and shearing. Therefore, it is necessary to deeply study the working performance of CFST under various stresses of compression, bending, shearing and torsion, and determine the form of the related equation of its bearing capacity. Since the existing studies on the correlation equations under various stresses are the fitting formulas after t...
