摘要
通过4块纤维增强石膏板的抗弯性能试验,分析了纤维增强石膏板的抗弯破坏机理,通过分析纤维增强石膏板的荷载—挠度曲线,荷载—拉应变曲线得到了纤维增强石膏板的抗弯刚度、开裂荷载和极限荷载。研究表明:纤维增强石膏板在水平均布荷载作用下的破坏机理类似于适筋梁的破坏。
In this paper,based on the experiment of 4 piece of fiber-reinforced plasterboard,the flexural capacity of the plasterboard is analyzed.Cracking load and limit load of fiber-reinforced plasterboard are proposed by analyzing load-deflection curve,load-tensile strain curve bending strength.It is showed that the failure mechanism of fiber-reinforced plasterboard under horizontal load is similar to that of a fitness beam.
