摘要
当前,高强钢已经在工程中得到应用,并取得良好效果.然而,由于相关的研究还不够深入,在一定程度上制约了其应用和发展.本文首先介绍了高强钢在国内外工程结构中的应用状况;然后总结了高强钢结构关键问题的研究成果,着重介绍了高强钢螺栓连接节点力学性能的研究成果;最后指出了高强钢螺栓连接节点的研究需要着重考虑的几个问题.现有的研究表明,高强钢螺栓连接节点具有较好的受力性能及延性,而现有规范不完全适用于此类节点的设计,尤其对于节点转动能力的估计等偏于保守,不利于此类节点的应用,进而也不利于高强钢结构优势的发挥.
Application of high strength steel(HSS)to engineering has achieved satisfactory results and therefore proves to be promising. Yet so far intensive study of HSS has not been systematically conducted, which to some ex- tent restricts its wide acceptance. This paper first presents an overview of the landmark buildings and major projects where HSS was adopted, and then summarizes the achievement in experimental study and numerical analysis of HSS, performance and mechanical properties of an HSS bolted endplate connection in particular. Finally, issues that one might be confronted with in the study of an HSS connection are discussed, and consequently future research work is specified at the very end. Current study has demonstrated satisfactory mechanical behaviour and ductility of such connections, and yet existing design methods appear to be conservative in some way, especially concerning the prediction of the end-plate rotation capacity, hence restraining both the application of such connections and fiLrther exploitation of the potential of HSS structures.
