摘　　要：通过6块加气混凝土屋面板的抗弯试验,研究板材跨度及板材强度对加气混凝土屋面板的延性、开裂荷载和极限承载力的影响。试验结果表明:加气混凝土屋面板以弯剪破坏为主,承载能力较小,延性比较好。开裂荷载作用下板的变形较大,工程中屋面板的受弯承载力应以变形和强度同时控制比较合理。采用MARC有限元软件模拟分析该楼板的变形和承载力,结果表明,有限元计算与试验结果吻合较好。To investigate the seismic behavior of autoclaved aerated concrete （AAC） roof panels, the bending test of 6 AAC panels was made for estimating their ductility, cracking load and ultimate bearing. The experimental results indicated that the failure pattern of AAC roof panels could be defined as the bending-shear failure. The load-carrying capacity of AAC panels was much lower than that of the normal ones and the ductility of the panels was pretty well. The bending capacity of AAC roof panels for actual projects should be controlled by the deformation and strength. Besides, the numerical simulations using the MARC was performed on AAC roof panels and the finite element results agreed well with experimental results.
