Movements in Bridges

Brunel Conference

MOVEMENTS IN BRIDGES

1 July 2004

Strength, stiffness and movement aspects are of fundamental importance in the concept, design, construction, maintenance and repair of bridges and similar structures. Yet the last in the trio i.e. the movements, due to the difficulties in predicting and estimating their nature and magnitudes, are often not well understood and catered for, to the detriment of the ensuing bridge structures. Movements, subtle and gross, arise from a variety of causes and occur throughout the life of bridges starting from the earliest construction stage.

Considerable knowledge of bridge movements and associated aspects exists in the profession. The Conference would provide a forum for engineers to discuss and highlight the crucial movements problem in bridges, consider the latest advances in understanding and technology and learn from leading engineers' and each others' experience. It is hoped that this would help to mitigate movement problems in existing bridges and minimise their occurrence in the new generation of bridges, improving their durability, performance and life prospects for the future.

Intended for:

Bridge design, construction and repair and maintenance engineers including supervisory engineers and discipline managers; manufacturers and providers of bridge materials and components; teachers, researchers and students of bridge engineering; railway, highway, infrastructure, transport and structural engineers and managers of associated sectors.

Objective:

To enable engineers at various levels to have an accurate appreciation and knowledge of the treatment of movements arising from the structural form, loadings, materials, environment, time and construction method related causes. This should lead to improvement in the repair and maintenance strategies for existing bridges and in the concept, design, construction and maintenance of future bridges and similar structures.
