Research on Model Test Program of Steel-concrete Composite Connection

Abstract

Based on the study on existing experimental research on steel-concrete composite connection, the experiment set up of the steel-concrete composite connection with cells of the Yongjiang River Bridge, is presented. The design theory of model test, comparison of model test program, design of steel and concrete, design of shear connectors and the deviation of model test are discussed. Especially for the design issues of shear connectors in a scale model, the finite element model of the small size of the shear connectors release test was established to calculate carrying capacity and shear stiffness. The constitutive relationship and failure criteria are discussed. The designing method of shear connectors in scale model test was proposed.
