某高层建筑项目屋顶设一长方块实体。为充分利用建筑空间，将该实体设计为钢结构通廊，采用两片高4.5m、跨度32m的钢桁架梁支撑。该梁承受竖向荷载及较大的风荷载的作用，为保障结构的安全可靠，对其进行了极限承载力研究，结果表明，该桁架梁具有良好的承载力，能满足受力要求。

A tall building has a block above the roof. In order to make full use of building space the block is designed as propylaea constructed by steel structure with two truss beam 4.5m high and 32m long. The beam is suffered by vertical loads and large wind loads and so it is necessary to study its ultimate bearing capacity for the purpose of its safety and reliability. The results show that the beam has excellent bearing capacity and meets mechanical requirements.
