Experimental research on the bending performance of removable steel and corrugated steel concrete composite beams
During troop movement and relocations,emergency rescues,and disaster relief operations,there is of-ten a short-term problem of constructing a large number of infrastructures that needs to addressed.The removable steel-corrugated steel concrete composite beam has the advantage of rapid assembly and disassembly compared to conventional steel-concrete composite beams.Unlike traditional corrugated steel used as the web of steel beams,this design incorporates corrugated steel with concrete to form the flange plates of composite beams,enhancing the flexural behavior while limiting damage to internal equipment and personnel from concrete failure.Through static loading tests on the removable steel-corrugated steel concrete composite beams,this study investigates the effects of flange plate thickness and bolt spacing on the flexural behavior of the composite beams.Additionally,ABAQUS simulations are employed to compare their flexural behavior with that of conventional precast reinforced concrete composite beams of the same cross-section.The experimental and simulation results indicate that under equivalent conditions,the removable steel-corrugated steel concrete composite beam can achieve a 20%increase in bearing capacity compared to conventional steel-concrete composite beams.Furthermore,the accuracy of component as-sembly and the connection quality between the corrugated steel and concrete significantly influence the load-bearing performance of the composite beams.
