福州国际机场收费棚大跨不等高砼屋面框架梁方案选择与设计

Scheme Selection and Design for Large-span Unequal Height Framed Roof Beam in Fuzhou International Airport Toll Station

针对福州国际机场高速公路主线收费棚大跨不等高屋面梁这一特殊结构设计,提出了斜柱支撑桁架梁结构和后张有粘结部分预应力混凝土大梁结构两种方案,并采用大型空间有限元软件进行了计算分析比较,对优选并成功实施的结构方案的设计方法进行了介绍,为类似工程设计积累经验。

Based on the special structure design for the large - span unequal height roof beam in the mail route toll station of Fuzhou International Airport, this paper introduces two structure scheme which are trussed beam supported by inclined column and pre - stressed bond with post -tensioned beam. According to the computational analysis and comparison by the large - scale - space finite element analysis program, this paper analyses the optimization for the structural design scheme, which gives reference to the other similar engineering design.
