建立了燃机房屋面空间三角管桁架整体计算模型和单榀计算模型。对燃机房屋面桁架支座采用铰接连接、滑动连接以及考虑燃机房双支柱约束的简化模型进行了计算分析。比较了燃机房屋面桁架各种计算简化模型的计算结果,分析了桁架支座约束、燃机房结构刚度、燃机房屋面混凝土板以及桁架单榀建模对设计结果的影响,可供工程设计参考。
The overall calculation model and single 榀 calculation model of the triangular trusses of gas turbine house roof are established. The simplified model of articulated connection, sliding connection and double pillar constraint in gas turbine engine room are calculated and analyzed for the truss support of gas turbine house. The computational results of various simplified models of the truss roof truss are compared. The influence of the truss support constraint, the rigidity of the engine room structure, the concrete slab of the turbine house and the truss truss modeling on the design results are analyzed. reference.
