【摘要】：近几年来,钢结构建筑正逐渐普及,越来越多的工业厂房甚至于民用建筑也开始使用钢结构建筑。工程上使用的纯圆管柱钢梁节点形式又过于单一,本文通过分析规范、规程上多种节点的利弊,提出新型分离式套筒节点,并结合新型分离式套筒节点和传统外环板节点的试验数据,深入对比两种节点的滞回特性、极限承载力、刚度等。本文主要进行了以下工作:1:设计了四个十字形钢管柱钢梁节点,其中包括一个传统外环板式节点,三个新型分离式套筒节点。通过试验得到了传统外环板节点和新型分离式套筒节点在低周反复荷载作用下的刚度退化、极限承载力、耗能能力以及延性等特征。2:通过改变套筒的厚度来分析这种新型分离式套筒节点在不同套筒厚度下节点的滞回曲线、耗能能力等受力性能,得到套筒厚度对新型分离式套筒节点受力性能的影响。3:将传统外环板式节点与新型分离式套筒节点的试验结果做对比分析,提出两种节点形式的利弊,为实际工程中使用新型分离式套筒节点提出有利的设计依据和意见。通过对比实验分析表明,这种新型节点相对于传统外环板式节点构造简单、节约钢材、抗震性能良好,具有一定的实际应用价值。
[Abstract]:In recent years, steel structures are becoming more and more popular, and more industrial buildings and even civil buildings begin to use steel structures. The pure tubular column steel beam joints used in engineering are too single. Through analyzing the advantages and disadvantages of many kinds of joints in the code and rules, a new type of split sleeve joint is proposed in this paper. The hysteretic characteristics, ultimate bearing capacity and stiffness of the two kinds of joints are compared with the experimental data of the new separated sleeve joints and the traditional outer ring plate joints. The main work of this paper is as follows: the design of four cross-shaped steel tubular column steel beam joints, including a traditional outer ring plate joints, three new split sleeve joints. The stiffness degradation and ultimate bearing capacity of the traditional outer ring plate joints and the new separated sleeve joints under low cyclic loading are obtained. By changing the thickness of the sleeve, the hysteretic curve and the energy dissipation capacity of the new type of split sleeve joints under different sleeve thickness are analyzed. The influence of sleeve thickness on the mechanical performance of new type split sleeve joints is obtained. 3. The test results of traditional outer ring plate joints and new separated sleeve joints are compared and analyzed, and the advantages and disadvantages of two types of joints are put forward. The paper puts forward the favorable design basis and advice for the use of new type separation sleeve joints in practical engineering. The experimental results show that compared with the traditional outer ring plate joints, this new type of joints has simple structure, saving steel, good seismic performance, and has certain practical application value.
