| Abstract: | According to the actual project,the holes of the doors and windows should be prefabricated,and the connecting beam above them should be set.Based on the experiments of six concrete-filled plasterboard beams,this paper analyzed the mechanism of the beam to stand against shearing force and the characters of destruction.Considering the influence of the plasterboard to shear capacity,a section conversion coefficient is introduced to the truss-model.With the truss-model,the mechanism that concrete works together with plasterboard is analyzed.Together with the results of the test and theory analysis,some conclusions are put forward. |
