| 摘 要： | 通过对国内外相关规范的分析、整理,对钢结构设计中承压型和摩擦型连接高强螺栓设计方法进行分析与探讨,揭示了目前工程界对摩擦型和承压型高强螺栓连接应用所存在歧义的实质,进一步得出摩擦型和承压型高强螺栓连接的计算方法实质是一致的,论述了在实际工程中大量应用承压型高强螺栓的合理性、经济性和可行性;同时指出,预拉力可大大加强节点的刚度且对高强螺栓的抗拉性能影响甚微。

| Abstract: | By the analysis of the related specialization about steel structure,it revealed the essence of the misunderstanding,which existed in applications of pretensioned bearing-type joints and slip-critical joints,and concluded that the calculation method of bearing-type joints and slip-critical joints was same.It explored the rationality,economy and feasibility of the large application of pretensioned bearing-type joints in practice.Also,it pointed that prestress can largely strengthen the joint ' s stiffness,and has little effect on tensile properties of heightstrength bolts. |
