In this paper, domestic steel-concrete composite beam research-based , and thus high-performance steel-concrete composite beam finite element analysis to study the shear behavior . The main contents : First, high-performance steel and elaborated summary of HPC applications and developments , and also introduces the development of composite beams , on the mechanical properties of composite beams made ??a systematic introduction to analysis for composite beams foundation ; Chapter II composite beams longitudinal shear , vertical shear and other calculation method and empirical formulas were analyzed , focusing on stud connectors of related experiments , working mechanism , failure mode and the carrying capacity of studs the system introduced for the finite element model analysis behind to establish a theoretical foundation. Ansys finite element software application Tsinghua University have done experiments carried out under the same conditions simulated composite beams , and verified the accuracy of the model ; combinations were established two high-performance composite beam and ordinary composite beams , analyze them and forces in the case of the same cross-section under stress , deformation, shear studs and slip and other effects , the results show that high-performance composite beams in force , deformation and slip ways than ordinary composite beams more favorable ; finally established six groups with cross-sectional dimensions and tendons connected in varying degrees the same high-performance composite beam , stud connection by changing its high-performance composite beam analysis the impact , the results indicate that connectivity for composite beams bearing capacity, deformation and slip has a significant impact, while also gives the effect of the specific circumstances , for high-performance composite beam design and application of reference.
