TL;DR: In this article, an analysis of the natural frequencies of cable-stayed bridges using both an analytical and a numerical bridge model is presented, and some comparisons between the analytical and numerical results are given, which validate the simple analytical model.
Abstract: This paper develops an analysis of the natural frequencies of cable- stayed bridges using both an analytical and a numerical bridge model. Useful results are obtained using an analytical model which is capable of accounting for the main parameters of the bridge. In particular, the influence of the tower parameters on the bridge free frequencies, including geometric nonlinearities, is investigated. Finally, some comparisons between the analytical and numerical results are given, which validate the simple analytical model. (A)

TL;DR: The Normandie Bridge as discussed by the authors is the world's longest cable-stayed bridge with an 865m main span, and it was designed to withstand high winds, because of its carefully designed reinforced concrete and steel composite deck.
Abstract: This paper analyses the design of the Normandie Bridge across the Seine Estuary in France, and reviews the experience gained in its construction. It is the first cable-stayed bridge to have very long spans; in this case its 865m main span is the world's longest cable- stayed span. It is specially designed to withstand high winds, because of: (1) its carefully designed reinforced concrete and steel composite deck, which has a streamlined cross section; (2) its Y- shaped pylons; and (3) its high torsional rigidity. Its use of high- performance concrete has great structural advantages. The erection of access spans on both banks of the estuary required the contractors to develop a new technology, the 'staircase' method for horizontal span launching. Such a procedure was made possible by the use of a series of sensors, and a central micro-computer, to control horizontal and vertical movements. The balanced cantilever method was used to erect the central part of the bridge. A new type of cable was used, and interconnecting ropes were used to reduce the cables' vibration periods. The design engineers were given total responsibility for the design, so that they could introduce improvements at each stage of the project.

TL;DR: In this paper, an analytical method for determining structural shapes, that uses a logical and rational approach to handle subjective variables, is presented for a variety of bridge designs, including cable-stayed and suspension bridges, where tensile stress prevails.
Abstract: This paper presents an analytical method for determining structural shapes, that uses a logical and rational approach to handle subjective variables. Its principles are illustrated for a variety of bridge designs. Considering statics in relation to shape, the basic conditions of an arched bridge structure can be reduced to the behaviour of: (1) the arch, which is mainly subjected to axial load; (2) the beam, which is mainly subject to bending moment; (3) arch and beam jointly, which are affected by both axial load and bending moment. Similar considerations apply to cable-stayed and suspension bridges, where tensile stress prevails. Statics can lead to a variety of equally valid formal design solutions; when considering how to choose between them, structure should be considered in a spatial context. From this viewpoint, design is a function of the structure's point of observation and the effects of light on it, together with geometrical and perspective aspects. In these terms, certain shapes can be defined for the design of a structure. The choice between various statically and contextually valid shapes should be made at the executive level, considering materials, construction engineering, executive methods, costs, timing, convenience to users, etc.

TL;DR: A cladding system was developed and incorporated into a sub-frame of purpose-made aluminium arches to provide an extremely cost-efficient solution to the problem of enclosing a deep central atrium at Chelsea and Westminster Hospital, London.
Abstract: Over the past 15 years the performance of clear foils has been greatly improved. Of all those developed so far, Ethylene Tetrafluroethylene is the most significant structurally, as it offers excellent tear resistance, has very high translucency, and weathers well. Foils have translucent properties sufficient for a wide range of activities to take place beneath them, such as sport and horticulture. Used as double or triple skin cushions, they can provide significantly better thermal insulation than double glazing at only a fraction of the total weight. Clearly such considerations are paramount for wide-span roofs. At Chelsea and Westminster Hospital, London, such a cladding system was developed and incorporated into a sub-frame of purpose-made aluminium arches to provide an extremely cost-efficient solution to the problem of enclosing a deep central atrium.
