Study on eccentric compression of rapidwall with concrete filled every one or more holes

Rapidwall(fiber reinforced gypsum board) has many merits such as environment protection,energy saving,resourceful and low cost etc.Study is made on eccentric compression of rapidwall with concrete filled every one or more holes,and analysis is made on destructive mode,the vertical load-bearing capacity,and the influence factors to the bearing capacity when the fiber reinforced gypsum board under eccentric compression.The conclusion is that the rapidwall with concrete filled every one or more holes used for bearing can satisfy the requirement of vertical load-bearing of common building but sufficient emergency capacity should be considered in design.The ultimate bearing resistance has great attenuation when the width of board from 1020 mm(concrete filled every two holes) to 1270 mm(concrete filled every three holes) in eccentric axial load test.Therefore in actual application components with concrete filled every one or two holes are more suitable.
