Experimental Research On Behavior Of Concrete-filled Glass Fiber-reinforced Plasterboard Under Horizontal Loading

Concrete-filled glass fiber-reinforced plasterboard (CFFRP) is made of plasterboard and concrete. The loading characteristics of this new system was studied in this article. The test is divided into two aspects. First,by the seismic experiment of the nine blocks of reinforced rapid-wall under cyclic lateral loading, the loading mechanism of these rapid-walls, containing carrying capacity, deformation, damage law and the Internal force of law,is discussed.Second, Five-story 1:1-scale model glass fiber-reinforced plasterboard building is tested under different axial loads. Crack distribution, cracking load and limit load of CFFRP are obtained under low-cycle loading. The Deformation and internal force distribution of CFFRP were studied. The comprehensive analysis of single wall tests and test results of the overall model test, the conclusions obtained include:1,Based on the experiment, the failure process and the failure mechanism of this rapid wall are systematically studied. Analysis of the main distribution of the wall cracks, we have got the destruction of the wall is due to shear failure caused by inadequate. As the axial ratio of the different characteristics of different shows, when the vertical stress is small, the cracks along the wall's overall skew diagonal crack; when the vertical stress is large, cracks along the concrete columns of the needle core short oblique fracture.2,Through the whole series analysis of test results available, the mechanical characteristics of the filled fiber gypsum board wall system in the role of horizontal loading is divided into two distinct stages, namely pre-yielding phase of the wall and the wall the yield of a later stage, showing the wall in two stages at different regularity.3,Through experiments, the internal force distribution of the wall is obtained, the walls in the elastic phase has a clear overall, and we can analysis, design as a shear wall,.and research results at home and abroad and proposed the calculation of shear resistance and normal section.4,Through the existing wall model theory of comparative analysis, combined with filling the composition of fiber-gypsum board, macro linear model for CFFRP is provided which is compose of many vertical-bar element and one shear element, and proposed definition and calculation of parameters。...
