1. Bracing of steel bridges during construction; theory, full-scale tests and simulations
Abstract : A number of steel bridges have suffered lateral-torsional failure during their construction due to their lacking adequate lateral and/or rotational stiffness. In most cases, slight bracing can be of great benefit to the main girders involved through their controlling out-of-plane deformations and enabling the resistance that is needed to be achieved.

2. Integrated structural and construction engineering – A study of project team performance in Swedish bridge design
Abstract : The Swedish Transport Administration (STA) ambitiously strives to increase the level of productivity and innovation within its operations while meeting and surpassing national sustainability objectives. In this effort, the STA has concluded that climate gas emissions from construction, operation, and maintenance of the infrastructure must be reduced for Sweden to maintain its position as a pioneer and to reach both national and global climate goals.

3. Fatigue of steel bridges : New structural details and the implementation of high strength steel
Abstract : The use of high strength steel has the potential to reduce the amount of steel used in bridge structures and thereby facilitate a more sustainable construction. The amount of steel and what steel grade that can be used in bridge structures and other cyclic loaded structures are often limited by a material degradation process called fatigue. READ MORE

5. Serviceability Limit State for Steel Girders during Bridge Launching - A Patch Loading Problem
Abstract : Incremental launching is a construction method in which bridge girders are first assembled in the vicinity of the future permanent position of the bridge. When the elements have been welded together the girders are launched to their permanent position. READ MORE
