| Abstract | ||||
| Glass fiber reinforced gypsum (GFRG) walls are relatively new building materials that have been developed in the last decade in Australia and are now being used in many other countries as structural walls. The GFRG wall panels are hollow panels made of phosphogypsum (an industrial by-product) and reinforced with glass fibers. These panels (120 mm thick) have rectangular cavities. With the increasing use of GFRG wall panels, structural design guidelines, based on proper studies have become necessary. In this paper, a method is proposed to predict the compressive strength of GFRG wall panels, including slenderness effects and non-linear stressstrain behavior of the material. These results also been validated with experimental results obtained from tests conducted and limited number of experimental results available in literature. It is seen that the proposed method gives more accurate results than the existing methods. | ||||
