摘　　要：纤维增强石膏板作为一种绿色环保墙体材料,它的优越性已经引起国内学术界和建筑业的广泛重视。通过对纤维增强石膏板抗弯性能试验结果的进一步分析,得到了纤维增强石膏板抗弯破坏极限应力和破坏机理,并应用有限元软件对试验结果进行验证。通过对四边简支双向石膏板进行有限元软件分析,得到了纤维增强石膏板四边简支时的变形特点,应力分布规律,开裂荷载以及两方向的弯矩比例。Glass fiber reinforced gypsum panel （GFRGP） as a green wall material its advantages have already attracted a lot of interests from academics and construction industry. In this paper, By analyzing the results of experiment of GFRGP, the ultimate stress and failure mechanism of GFRGP are proposed , and application of finite element software to verify test results. Based on the finite element software analysis of GFRGP with four sides simply supported, the deformation characteristics, stress distribution, cracking load and bending moment ratio of two directions of GFRGP are proposed
