    摘要:

    为满足建筑设计的美观性和通透性要求,对某建筑观光大厅12m高玻璃幕墙的桁架支撑体系进行选型分析,采用有限元软件SAP2000分别对钢桁架支撑体系和索桁架支撑体系进行对比计算分析。计算结果表明,两种桁架体系的应力水平和位移情况均满足设计要求。在风荷载、地震荷载以及控制荷载组合工况作用下,钢桁架弦杆的应力比大于索桁架,腹杆应力比远小于索桁架,索桁架的位移略大于钢桁架的位移。综合位移与应力比的大小,选用索桁架作为玻璃幕墙的支撑体系。

    Abstract:

    In order to be satisfied with the aesthetic property and permeability required by architectural design, type selection analysis for support truss system with 12 meters height in curtain wall of sightseeing hall were carried out. The FEM software SAP2000 was employed for the comparing computations of steel truss and cable truss. The calculating results showed the stress ratio and displacements of the above two type trusses were satisfied with design codes. Under the given wind case, the quake case and the combined load cases, the stress ratio of the chord members in the steel truss is greater than the cable truss, the stress ratio of the web members in the steel truss is less than the cable truss, and the displacements of cable truss is greater than steel truss. Considered the values of the stress ration and displacements of the two types of truss, the cable truss is chosen to be used as the support system of curtain wall of the sightseeing hall.
