为了提高胶合木-钢夹板螺栓连接构件抗剪承载力的计算精度,在考虑构件厚径比的影响下,对单螺栓连接的胶合木-钢夹板连接构件进行了抗剪性能试验。采用推出试验的方法,设计了5大组,3小组共45个推出试件,探究其从加载到破坏整个过程中的剪切破坏情况。基于销槽承压理想弹塑性模型、螺栓连接的承载力理论与Johansen的"屈服理论",提出了3种螺栓连接在抗剪承载力下出现的剪切破坏模式,并推导出胶合木-钢夹板螺栓连接构件的抗剪承载力计算公式。试验结果表明:胶合木-钢夹板单螺栓连接中,随着厚径比的增大,螺栓连接破坏模式会逐渐由"单铰"破坏模式变成"双铰"破坏模式。通过推导式计算的胶合木-钢夹板螺...

In order to improve the calculation accuracy of shear bearing capacity of the joint members of the plywood and steel plywood,under the influence of the thickness ratio of the component,the shear performance test was carried out on the joint component of the glue-steel splint connected with single bolt.Adopt the method of push-out test,5 groups of 45 specimens were designed,the shear failure of the whole process from loading to failure is discussed,an ideal elasto-plastic model based on pin-groove pressure,theory of bearing capacity of bolt connection and Johansen"Yielding theory",The shear fai...
