建筑结构与形式的完美结合——宁德站站房结构设计

摘要

The close combination of the building form and internal structure was exhibited in the design of Ningde Railway Station.The 48m span entrance with inclined strut,working in concert with the building elevation characteristic model of gallery bridges,created favorable conditions for the arch centering application.The base horizontal counter-force was reduced skillfully employing self-balancing steel strand.The symmetrical and cantilevered station roof was realized directly by the four-pyramid space truss structure.The effect of visible supporting structure was employed for the platform canopy.Employing with the structural form consisted of castellated beams,vierendeel truss and rectangle steel columns,the lighting space was enlarged,the architectural style was realized by the beauty of structure.Then the structure design of Ningde Railway Station was introduced in detail,especially the design of arch centering structure and castellated beam.It can be used as a valuable reference for the design of similar structures.%宁德站站房的设计体现了建筑形式与内在结构的有效结合:入口48m跨的门洞采用斜撑构图,与建筑立面廊桥斜撑的造型特征相呼应,为拱架结构的使用创造了有利条件.拱架中自平衡钢绞线的使用,巧妙地降低了拱底水平推力.站房采用对称处理,大屋面向两边斜挑,可直接通过正四角锥网架结构实现.站台雨棚采取结构直接外露的效果.由蜂窝梁、空腹桁架和矩形铜柱组成的梁柱结构形式,扩大了采光空间,以结构美实现了雨棚的建筑形式.该文详细介绍了宁德站站房结构设计全过程,重点论述了拱架结构和蜂窝梁结构设计,可为相关工程设计提供参考.
