摘　　要：通过现场静载试验和数值模拟分析相结合的手段,研究了双T型截面屋面板在受弯作用下的结构性能,模拟结果和实测数据表明,受弯双T板跨中产生最大变形,在结构表面发生初次开裂前,由混凝土和钢筋共同承受拉力,当发生开裂后逐渐转变为由钢筋承受主要拉力,结构变形速率增大,构件性能符合安全生产要求。模拟和实测结果基本吻合,反映出有限元模拟方法较为可靠,可作为结构性能验证的有效补充。This article combines on-site static load tests and numerical simulation analysis to study the structural performance of double T-shaped roof panels under bending.Simulation results and measured data show that the maximum deformation occurs at the mid span of the double T-shaped panels under bending.Before the initial cracking occurs on the surface of the structure,the tensile force is jointly borne by the concrete and steel bars.After cracking occurs,it gradually transforms into steel bars bearing the main tensile force,and the deformation rate of the structure increases,The performance of the components meets safety production requirements.The simulation and actual measurement results are basically consistent,reflecting that the finite element simulation method is relatively reliable and can serve as an effective supplement to structural performance verification.
