| Abstract: | 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 |
