道顿竞技馆(Dorton Arena)开启了现代索结构开端,其将建筑与结构的完美融合以及在建筑结构设计方面的多项创新使其在工程领域获得了极高的声誉,但国内诸多文献中对于该场馆是多有提及却少有介绍.该馆在建筑和结构设计方面的创新有:体系设计上采用了交叉斜拱骨架和马鞍形双曲索网,将建筑理念直接通过结构表现出来;充分利用了混凝土拱受压、索网受拉的特点,整体形成简洁高效的自平衡结构体系;屋面张力体系中的双曲索网,既能够抵抗向下的重力荷载,又可在风吸作用下实现主副索作用转换,抵抗向上的荷载作用;在周边索网的交点设抗风索与周圈立柱连接,将整体索网向下牵引,在保持屋盖双曲面造型的同时控制索网屋盖的风振作用;斜拱交叉连接设计可以平衡斜拱在拱脚处产生的推力,斜拱在交汇之前断开通过“铰”连接,以在受到不均匀荷载下允许结构的微小调整;延伸的倾斜拱脚与交叉端下部立柱共同组成“三脚撑”结构,并在两倾斜拱脚基础处引入预应力拉索以阻止拱脚在推力作用下的滑移.整个场馆在建筑和结构中各项创新性的设计,对于后续张力结构的发展和研究有着重要的历史意义.本文对道顿竞技馆的历史背景、建筑结构方案设计、结构深化设计、施工以及该场馆的历史意义等方面作简要介绍,旨在使这一将建筑和结构设计充分融合的经典工程得到更深入的了解.
Dorton Arena opened the door to the beginning of the modern cable structure. Its perfect combination of architecture and structure, as well as a number of innovations in the design of building structures, have given it a high reputation in the field of engineering. However, in many domestic literature There are many references to the venue but rarely introduced.The museum in the architectural and structural design innovations are: the system design uses a cross-slanting arch skeleton and saddle-shaped hyperbolic cable, the architectural concept directly through the structure of the show ; Take full advantage of the compression of concrete arch, rope tension characteristics, the overall formation of simple and efficient self-balancing structural system; roof tension system hyperbolic cable network, both to withstand the downward gravity load, but also in the wind suction Under the action of the conversion of the main and auxiliary cables to resist upward load effect; at the intersection of the surrounding cable network anti-wind cable connected with the peripheral columns, the whole cable network down traction, while keeping the roof hyperboloid shape control cable The wind-vibration effect of the mesh roof; the cross-arch cross-connect design balances the thrust produced by the ramp at the arch foot, and the ramp is disconnected by the “hinge ” connection before being intersected to allow the knot Of the small adjustments; extended inclined arch and cross at the bottom of the column together constitute “three feet ” structure, and the introduction of prestressed cable at the base of the two inclined arch to prevent the arch foot sliding under the thrust force. The innovative design of venues in architecture and structure has an important historical significance for the development and research of the follow-up tension structure.This paper analyzes the historical background of Doton gymnasium, the design of architectural structure, the deepening of structural design and construction, The historical significance of the brief introduction, designed to make this fully integrated architectural and structural design of the classic project to get a better understanding.
