钢结构中使用高强螺栓连接,与使用焊缝连接,传力方式虽不相同,但变形特征相似,因而有可能将两者混合使用于同一结构,而且,近年来已见于一些国家的钢结构规范。目前,我国高强螺栓的应用日见广泛,若能考虑将焊缝与高强螺栓混合使用,这对简化连接节点,改善各自受力性能,特别是改造旧结构或处理工程质量问题,更会有明显的经济效果。为此,我们特对这一混合连接方式的受力性能,进行了试验分析。
The use of high-strength bolts in steel structures is connected with the use of welds. Although the force transfer methods are not the same, but the deformation characteristics are similar, it is possible to use both in the same structure, and in recent years, the steel structure specifications have been found in some countries. . At present, the application of high-strength bolts is widely used in China. If we can consider the use of mixed welds and high-strength bolts, this will simplify the connecting nodes and improve their stress performance, especially the transformation of old structures or the treatment of project quality problems. The economic effect. To this end, we conducted a trial analysis of the mechanical properties of this hybrid connection.
