通过两块足尺寸压型钢板-混凝土组合楼板试件的静力加载试验,分析组合楼板的破坏过程、破坏形态和滑移发展规律。利用ABAQUS有限元软件进行模拟分析,并与试验结果对比,验证有限元模拟方法的可行性。建立大跨度组合楼板的有限元模型,基于m-k法对模拟数据进行线性回归,得到适用于大跨度组合楼板的纵向剪切粘结力计算公式,为工程设计提供依据。
The static loading tests of 2 full-size profiled steel sheeting-concrete composite slabs were conducted to study the failure process,failure pattern and slip development law of the composite slab.ABAQUS finite element software was used for simulation analysis,and the results was compared with experimental results to verify the feasibility of the finite element simulation method.The finite element model of large-span composite slab was established and m-k method was used to conduct linear regression on simulated data to obtain calculation formula of longitudinal shear bonding force of large-span composite slab,providing a basis for engineering design.
