Title: Numerical Simulation Research on Bearing of T-Section Steel-Encased Concrete Composite Beams
Abstract: The Paper established nonlinear finite element model of steel-encased concrete composite beam by means of ANSYS program based on the tests of bearing performance of T-section steel-encased concrete composite beam.When establishing the model,the subject particularly emphasized the choosing of concrete nonlinear constitutive relationship,the separated model building method of steel bar,concrete and Steel-encased concrete composite beam,and the key techniques of treating bonding and slipping of steel beam and concrete.Using the model,the procedure analysis of bearing and distortion of steel-encased concrete composite beam from being loaded to destroyed were carried out.The test phenomenon and results were analyzed.The limit bearing capacity and flexibility of composite beam,and stress and strain of the steel and concrete are achieved.Compared with the test results,the calculated values have better compatibility with it.It shows that the established finite element model can reasonably analyze the bearing of steel-encased concrete composite beam.
