Emergency repair of the port’s construction of reinforced concrete structuresrequired convenient, fast, avoid using large construction equipment and emergencyuse only after the completion of a simple reinforcement can be as long-term use ofpermanent structures. This paper proposes a composite slab: SRC (Steel-ReinforcedConcrete) composite slab, mainly to solve thin thickness of profiled steel sheet incommon steel-concrete composite slab, poor stiffness of the member and low carryingcapacity of the composite slabs. SRC composite slab used in two stage, the first stage,the steel panel which the section steel is welded on steel sheet at regular intervals canbe emergency use, to meet the timeliness requirements; the second stage, pouringconcrete in the steel panel, the composite slab that is formed can put into normal use.It has a unique advantage to a certain extent that combined emergency use withlong-term use.SRC composite slab did not study at home and abroad reported. In this article,mechanical properties of composite slab were studied and analyzed on experiment,and the main effect factors on the mechanical properties of SRC slab was analyzed inthe test such as section steel types, stud number, thickness of composite slab. Thefailure mechanism, mechanical properties and deformation properties of thecomposite slab was incuded in the study. Through experimental research and analysis,to find out a reasonable section steel type of composite slab; proposed calculationformula of deflection, yield strength, ultimate strength of composite slabs consideringslip between steel and concrete; proposed calculation formula of capacity anddeformation.At the same time, non-linear finite element analysis were carried on. By a finiteelement model, using ANSYS finite element analysis software to simulate the wholeprocess of testing, and finally, on the numerical analysis and experimental resultswere compared, the results fit well.
