对乐清体育中心“一场两馆”建筑、结构设计中主要的成果作简要介绍.“弯月”体育场采用空间索桁体系,其主要结构特点为环索分叉、径向索交叉.体育馆和游泳馆均采用张弦网壳结构,其主要结构特点为压杆不竖直、环索为空间曲线.“一场两馆”建筑设计规而不拘,结构方案设计时有一定挑战性.本文旨在粗略回顾与反思大跨度新型空间结构设计中所必须把握的关键技术问题和解决思路,给出结构设计如何做到与建筑设计协调与统一的过程.
Architectural and structural design work of roof system of Yueqing Olympic Center are roughly reviewed in the present paper. The stadium with lunar shape adopts a novel type of spatial cable-frames. System constitution of this stadium is different because of braced radial cables and open-mouth hoop cable. The gymnasium and swimming arena adopt a new latticed-shell-string system with non-vertical compression bars and spatial hoop cables. Structural design of steel works of Yueqing Olympic center is in accordance with mechanical rules and restrictions but not constrained by common concepts. It is a little challengeable in some aspects. The present paper aims at roughly review of some key design techniques of new types of large-span spatial structures. Emphasis is put on the process of architectural design and structural design when they do not coincided with each other at the preliminary design stage.
