Experimental Research And Finite-element Analysis On The Seismic Performance Of Fiber-reinforced Plasterboard Filled With Concrete

In Recent years, with the enhancement of the people's environmental awareness and the successful application of plasterboard in the structure projects, more and more relevant research is focused on this topic for discussion. However, because most recent plasterboards are used in internal decoration such as ceiling suspension, or in non-structure components such as nonbearing walls and so on, there is little mature researches on fiber-reinforced plasterboard used as main wall. This paper, by anti-seismic behavior experiments of fourteen 14 blocks of fiber-reinforced plasterboards filled with concrete under cyclic lateral loading, studied the capacity of shearing force and distortion, failed characteristics, the ductility and energy absorption of anti-seismic behavior of different concrete-filled styles under cyclic lateral loading, together with the research of the properties of rigidity degradation. This article draw a conclusion that the fiber-reinforced plasterboard fully filled with concrete is similar to the shear wall with slot; however, the one partly filled with concrete is similar to the composite brick masonry wall, and both have excellent anti-seismic behavior.Besides, by using the nonlinear finite-element method, this article made a practical mechanic analysis model, offering a useful and effective reference for later computer simulative experiment of all kinds of specifications fiber-reinforced plasterboard.
