悬索桥Cable Stayed Bridges.pdf简介：

"悬索桥Cable Stayed Bridges.pdf" 是一份关于悬索桥的详细技术文档或者研究论文。悬索桥是一种由高塔支撑、主缆（或钢缆）作为主要承重结构的桥梁类型。这种桥梁主要通过将主缆拉伸到桥两端的高塔上，将桥面的重量直接传递到塔上，从而减少了桥梁的跨度需求。悬索桥的特点是美观、结构稳固，能够跨越长距离的水域或山谷，适用于复杂的地理环境。

在这份PDF中，可能包含以下内容： 1. 悬索桥的历史和发展 2. 设计原理与计算方法 3. 构造技术与材料选择 4. 工程案例分析 5. 安全性与维护 6. 悬索桥与环境影响的考虑 7. 当前的研究热点和未来发展方向

阅读这份文档，可以帮助你深入理解悬索桥的构造、工作原理，以及在实际工程中的应用和挑战。

Ihe cost of manufacture of steel sections is, today, very high. It is thus necessary to analyse very carefully all the consequences of the choice of the deck system in order to obtain themost satisfactory overall answer.

An ingenious method was developed for placing the cables Steel ducts were hoisted, in advance, towards the pylons, bymeans of a system of wheels, rolling over the preceding stays. The cables were then threaded into these tubes without anchorages to the pylons, the strands being

directly supported on saddles. This new design was later used, with success, in several major structures, such as the bridge at Coatzacoalcos in Mexico (Fig. 328), and even the Sunshine Skyway Bridge in Florida (central span of 360 m) Whilst the transverse sections of these structures are similar,

the inclined struts and anchorages within the box sections have had to be strengthened In addition, so as to reduce the excessive width of the deck, due to the presence of central Pylons (Brotonne, Sunshine Skyway), these have sometimes been separated overthe lowerpart (Coatzacoalcos)

of making the best use of local steel manufacture on the other. During the preparation of the design, the delicate key problem of ascertaining to what extent the participation of the concrete in resisting normal forces would be reduced by shrinkage and creep was the subject of long debate. It was finally stipulated that this normal force should act only on the steei, calling for stiffening of the main beams

The choice between lateral and central suspension is the critical factor which governs the transverse design of pylons IThe advantages and disadvantages of these two types o! stay formation are given in a general manner in S 322

Where lateral suspension is envisaged, the design of the pylons should be based on the following conditions:
