手柄连接节点的力学性能试验研究

Experimental study on the mechanical properties of the connection node

针对热塑性长纤维增强复合材料模板体系中连接手柄和手柄连接节点的纯剪试验研究,探讨其破坏机理。实测结果表明:当集中荷载达到临界荷载时,墙体模板的边肋或端肋出现断裂,而连接手柄未发现破坏或明显变形。计算手柄连接节点抗剪承载力时,基于安全宜按铰接考虑。

Study on the handle and connecting node in the thermoplastic long fiber reinforced composite template system of the pure shear test, its failure mechanism is discussed. Measured results show that when the concentrated load reaches the critical load, the side rib or the end rib of the wall template is broken,while the handles do not find any damage or obvious deformation. When calculating the shear resist- ance of the connecting node, it should be considered by hinge based on security.
