In this paper the design of the supports of the Viaduct over the Alberche river is undertaken, using the method proposed by the FIP Recommendations 1996 (FIP96) [1]. The solution, thus obtained, is then compared with two non-linear analysis, taking into account non-linear material behaviour, as well as non-linearity due to changes in geometry, with different degrees of simplification.

The objective of this fib text is to explain some of the essential arguments which lie behind the resisting aspects of structural concrete. This chapter aims at providing ideas on how to conceive/create structural solutions for different structural problems, from a global perspective allowing to take advantage of, among others, the knowledge to which reference is made in the other chapters of this text.

The structure is located inside an aquatic park existing in Tenerife (Spain). The roof had to cover a grandstand for a dolphin show. There was a concrete structure with several columns initially designed to support a cantilever conventional roof. The structure had to cover an area of 3000 m2 with a free cantilever of 15.0 m. The general condition given by the client was to maintain the activity of the park while the work was done. A light membrane structure was selected to avoid cranes during erection. All the elements were designed to allow the installation by hand. (To continue reading, download PDF)
The Vinalopó bridge is the result of a design competition which sought to provide a new landmark for the city of Elche. One of the initial tasks was to deal with the traffic requirements of the local urban environment. It was necessary to build a roundabout on one side of the river in order to solve the traffic problems created by the junction of different avenues. The historical town is located on the opposite side. (To continue reading, download .pdf)
In this paper the main features of the Construction project of the widening of Los Santos Bridge are discussed. The project involves the widening of a major 600 m long bridge with spans of 150 meters increasing the width of the deck from 12.00 to 24.00 meters, without recurring to an independent structure. The project is based on the idea of providing minimum strengthening of the existing structure. This approach has allowed very important savings but has also required a challenging design project some aspects of which are discussed in this paper. (To continue reading, download .pdf)
