摘　　要：某桁架式钢结构大跨度燃气管道支架由三角形立体管桁架、活动支架与固定支架组成,介绍该类型支架的设计方法及构造措施。基于MIDAS软件分析支架的静动力性能,结果表明该类支架具有较好稳定,注和承载能力,并可避免由于场地土振动引起的结构横向摆动。This paper would present the design of the large span gas pipeline bracket from a steel project in the form of steel structure truss. The bracket was composed of three-dimensional triangular pipe truss, the movable bracket and the fixed bracket. Detailed introduction of design and construction measurement of this bracket would be made in the pape匚 Meanwhile the static and dynamic performance of the bracket was analyzed by means of the MIDAS technique. The study shows that this type of bracket exhibits excellent stability and load capacity as well as preventing the structure from horizontal swing caused by the ground vibration.
