摘　　要：部队移防换防、抢险救灾时会短时间面临大量基础设施建设问题。可拆卸钢-波纹钢混凝土组合梁与普通钢-混凝土组合梁相比,具有可快速拆装的特点;与传统波纹钢作为钢梁腹板不同的是,将波纹钢与混凝土结合用作组合梁翼缘板,在提升组合梁抗弯性能的同时可限制混凝土损坏对内部设备、人员的损伤。通过对可拆卸钢-波纹钢混凝土组合梁的静力加载试验,研究了翼缘板厚度以及螺栓间距对组合梁受弯性能的影响,并采用ABAQUS仿真计算,对比其与同截面普通预制钢筋混凝土组合梁的受弯性能。试验与仿真计算得出:同等条件下可拆卸钢-波纹钢混凝土组合梁相较于普通钢-混凝土组合梁的承载力可提升20%,并且试件加工装配精度和波纹钢与混凝土之间的连接程度会影响组合梁承载效果。During troop movement and relocations,emergency rescues,and disaster relief operations,there is often 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 assembly and the connection quality between the corrugated steel and concrete significantly influence the load-bearing performance of the composite beams.
