summary The bridge deck has a apparent simple shape, but it is the result of an adequate combination of two longitudinal geometric components: the deck shape evolution along de longitudinal section the layout of the road, that acts in simultaneous over a cross section, defining the deck exact shape. A geometric modelling computer programme was developed for box girder decks, allowing the generation of cross sections along the deck, defined with correct shape and location. In the elaboration of the deck plan drawings, the geometric information of the real deck shape is required. This information is not managed in an integrated and automatic way. On the creation of these drawings, directly executed over a graphic system, the time consumed is considerable and it is easy to comet errors. This paper describes the drawing module included in the computer program refereed. The deck plan projections are obtained, in DXF format drawing files, using the geometric information obtained from 3D-deck model. Using the drawing module it is possible to generate the usual deck drawings required in bridge design process. Then, his module is a great support for the design process within its geometric design stage.

title Oeresund Bridge. Temperature and cracking control of the deck slab concrete at early ages
source Automation in Construction 9 (5-6) (2000) pp. 437-445
summary High performance features are required of the concrete for the deck slab of the bridge over Íresund Straight between Denmark and Sweden and, among them, great durability. To guarantee this, it is necessary to assure, in advance, and control during the construction of the deck slabs, that the maximum temperatures and the traction stresses in the deck slab will not be greater than the allowable values, and to control these factors during the construction process. Before beginning construction, the deck slab was calculated using a program of finite elements that considers the heat generated, the shrinkage and creep of the concrete and the ambient conditions. To control the temperature during construction, temperature sensors are installed in various sections of each of the 49 deck spans and the temperatures produced during the first days of hardening are recorded on a computer. The temperatures of the components are also measured in order to estimate the temperature of the fresh concrete.
