摘要：

介绍了装配式斜支撑节点钢框架结构的优势和工程实践案例,分析了其结构布局、构件形式、构造措施、连接节点和受力机理. 针对该结构框架梁均为桁架梁、柱端设置小型斜支撑、构件数量多等特点,提出相应的结构计算方法,解决了装配式斜支撑节点钢框架结构的多个计算难题,包括选择合适的计算软件、桁架梁等代简化、确定柱计算长度系数、验算桁架梁细部强度等. 将计算结果与设计规范、试验研究及工程实践进行对比,验证了计算方法的可靠性.

The advantages and engineering practice cases of prefabricated steel frame structure withdiagonal bracing joints are introduced, and its structural layout, component form, construction measures,connection joints and stress mechanism are analyzed. Aiming at the characteristics of the frame beam ofthe structure, the small diagonal bracing at the end of the column, and the large number of components,the corresponding structural calculation method is proposed, which solves many calculation problems ofthe prefabricated steel frame structure with diagonal bracing joints, including the selection of appropriatecalculation software, the simplification of the truss beam, the determination of the effective lengthcoefficient of the column, and the checking of the detailed strength of the truss beam. The reliability ofthe calculation method is verified by comparing the calculation results with the design specifications,experimental research and engineering practice.
