【摘要】：主要通过试验研究与数值模拟,分析钢板-混凝土组合板在受剪状态下的承载力、变形、裂缝发展情况以及钢板与混凝土参与抗剪程度等。进行了3块钢板-混凝土组合板试件和1块无钢板混凝土试件的抗剪承载力试验。结果表明:钢板-混凝土组合板试件的剪切破坏形式主要是斜拉破坏;钢板承担了约50%以上总剪力,由于钢板的协同作用,混凝土承担的剪力与按照规范计算的混凝土抗剪承载力相比有较大幅度的提高;随着栓钉间距的增大,构件的抗剪承载力减小。基于修正压力场理论对ABAQUS进行了材料层面的二次开发,建立了适合钢板-混凝土组合板抗剪分析的数值仿真模型,模拟结果与试验结果吻合较好。
[Abstract]:Through experimental research and numerical simulation, the bearing capacity, deformation, crack development and the participation of steel plate and concrete in shear resistance of steel plate and concrete composite slab under shear condition are analyzed. The shear bearing capacity of three steel plate and concrete composite slabs and one steel sheet concrete without steel plate were tested. The results show that the shear failure form of steel plate and concrete composite slab is mainly cable-stayed failure, the steel plate bears about 50% of total shear force, because of the synergistic effect of steel plate, Compared with the concrete shear capacity calculated in accordance with the code, the shear capacity of concrete is greatly increased, and the shear capacity of the members decreases with the increase of the spacing between the studs. Based on the modified pressure field theory, the secondary development of Abaqus on the material level is carried out, and a numerical simulation model suitable for shearing analysis of steel plate and concrete composite slabs is established. The simulation results are in good agreement with the experimental results.
