In this paper, shearingmechanism in the joint core region is analysed from crack to limit state, on the basis of shear test of wrapped steel joint under the monotonic load.
The utility model removes the shearingmechanism of the prior art, etc. The utility model has the advantages of simple structure and convenient operation, and the cost of the utility model is reduced.
本实用新型去除了现有技术中的剪断等机构，使其机构简单，操作简便，而且降低了该设备的成本。
