Abstract

The invention discloses a finite element modeling method used for stud connector design of a steel-concrete combined beam. The method comprises the steps of writing scripts to build stud connector steel-concrete combined beam entity three-dimensional models with different diameters, heights, spacings and material characteristics in a control manner through a Python language interface of finite element software ABAQUS; and performing statics calculation analysis on the models. According to the method, the nonlinearity and damage characteristics of materials are fully considered; the interactionof a steel beam, a steel bar, a concrete wing plate and a stud connector is accurately simulated; stresses and deformations of all parts of the combined beam and the connector can be obtained; and abasis is provided for the stud connector design of the combined beam. By utilizing parametric modeling, the repeated work is effectively reduced; and a module framework is clear in thought, thereby being convenient for technicians to master and use.

Description

Technical field: [0001] The invention relates to a finite element modeling method for the design of stud connectors of steel-concrete composite beams, and belongs to the technical field of civil engineering design. Background technique: [0002] Steel-concrete composite beam is one of the structural forms widely used in highway and urban bridge engineering. In the steel-concrete composite beam, the shear connector, as the key component that combines the steel beam and the concrete wing, plays the role of transmitting the longitudinal shear force between the steel beam and the concrete wing, and is a steel-concrete Composite beams are the prerequisite for fully exerting their bearing capacity. Stud connectors are the most commonly used shear connectors, how to design their quantity and specifications has an important impact on the performance of composite beams. [0003] Many researchers at home and abroad use theoretical analysis, experimental research and numerical simula...
