Abstract: In order to study internal force development and force system evolution process of concretefilled glass fiber reinforced gypsum wall panels(composite board for short) under horizontal distributed load,the simplified calculation model was set up on the basis of the feature of the composite wall panels. At first the frame and plasterboard wall started to bear the force and then cracked, which would have the plastic deformation, and could reach the ultimate bearing capacity. This was actually a process that stiffness of frame and plasterboard attenuated respectively. Their distortion was unisonous. The stiffness of the frame and plasterboard in different stage was defined. The route of distortion, internal force simplified calculation method and flow chart were also given. Finally, the theoretical and experimental results were also analyzed by comparison. All the calculated results proved that the calculation method coincided well with the experimental results.

Key words: horizontal distributed load, glass fiber reinforced gypsum wall panels, core concrete, stiffness, simplified calculation method
