Calculating Method Study For Hss-concrete Experiment Composite Beam And Fea

In order to investigate the capacity of HSS(high-strength steel)-concrete composite beams under static load,two simply-supported beams were tested.The two beams were all full-interaction,and the major parameters included the strength of steel. Directional monotonic loads were applied and the test measurement included vertical load,deflection,strain,and slip,etc.All specimens failed in bending mode and exhibited good composite action. This text pass HSS-concrete composite simply-supported beams research, study HSS-concrete composite beams of break characteristic and capacity, analysis HSS-concrete composite beam of bending capacity calculation method; The test results show that the HSS-concrete composite beams shear capacity to be far larger than current simplified plastic theory;According to the experimental research on the test beams and analysis of other available test results,the formulae are derived for the ultimate shear capacity with consideration of the contribution from concrete flange.This study provides the basis for the application of HSS in steel-concrete composite beams.On top of that, this text help from FEA method, use ANSYS, full make use of experiment the data carry on verification, get reasonable of FEA space calculation model, to HSS-concrete composite beam of the mechanics function make further study, make up experiment amount of shortage;Pass number imitate, research HSS-concrete combination beam concrete wing knothole thickness, concrete mark various factors such as number and the steel beam stomach plank thickness etc. variety to HSS-concrete composite beam mechanics function of influence, end analysis result combine make with norm correspond of contrast.The research is HSS-concrete composite beam at our country of application and later of research work provide some reference.
