竹结构材连接件的承载能力

The bearing capacity of the joint composed by laminated bamboo lumber

对竹结构材螺栓连接件的承载力和破坏形态进行了静载实验研究,结果表明:用竹结构材连接件的结构具有较高的强度、刚度,以及很好的延性。竹结构材连接件的夹板与螺栓同时达到弯曲变形破坏状态,具有较好的整体受力特征,能够保证剪力的可靠传递。

The bearing capacity and failure form of the joint composed by laminated bamboo lumber and steel bolt were studied by static loading experiment. The result showed that the laminated bamboo lumber joint displayed high strength, rigidity and excellent tensility. The main board and bolts of joint failed at the same time. It indicated that the laminated bamboo structure laminate could ensure the effective transmission of shear and showed reliable load resistance integrality.
