1·Relatively comprehensive test study on the strength capacity of the reinforced concrete beam under bending moment, shear force and axial tensile force was carried out.

对弯、剪、轴拉复合受力状态下钢筋混凝土梁的承载能力进行试验研究。

2·This paper discusses the application of calculation formulas of high strength bolt connection in bearing type under the action of both shearing force and axial tensile force.

本文讨论了承压型高强度螺栓连接在同时承受剪力和杆轴方向拉力时其计算公式的应用。

3·When connection come into the phase of larger deformations, axial force turn into the tensile force, prevent the further deform, it means that catenaries action occur.

进入大变形阶段后，连接轴向约束压力变为约束拉力，轴向拉力阻止钢梁自身进一步变形，发生了悬链线效应。
