摘　　要：节能复合墙板是由两块钢筋混凝土面板和聚苯板芯层通过斜钢丝可靠连接的复合板,具有较高的抗弯刚度和承载力,而且强度重量比高。复合墙板内混凝土面板的配筋率、洞口尺寸等参数均对复合墙板的抗弯极限承载力有影响。本文对4块复合墙板的足尺模型进行板面法向均布荷载作用下的极限承载力试验,并与ANSYS有限元软件分析结果相比较。结果表明在弹性阶段内二者较为一致,验证了计算模型的合理性,但混凝土开裂后,二者偏差较大,需要对有限元数值模型加以修正。Energy-saving composite sandwich panels are commonly constructed of two wythes of concrete separated by a layer of thermal insulation. The concrete wythes are connected to each other by spatial steel truss shear connectors. The reported study demonstrates that these panels have high flexural rigidity, bearing capacity and high strength-weight ratio. The ultimate load-bearing capacity of sandwich panels was affected by the reinforcement ratio, the size of hole, and so on. In this paper, four full-scale energy-saving composite sandwich panels under transverse load were studied experimentally, and the experimental data were compared with the results of finite element analysis （FEA）. A good match between the FEA results and experimental data was obtained in elastic stage, but there was a little disagreement between them after concrete cracked, the present numerical model should be verified for further research.
