ABSTRACT

As bridges are engineering work which is destined to last for several decades and even centuries, they are bound to suffer from damage and disruption. The causes are diverse: climatic disturbances (wind, rain, earthquakes), ageing materials, accidents, eventual consequences of the traffic. It is thus necessary to regularly assess the state of the structure and the equipment ion order to verify the good functioning and security of the bridge. When a reinforcement or repair is required, methodologies are to be followed and principles are to be respected. This article notably focuses on the case of metallic bridges and details the main repair methods as well as the measures to be implemented in order to prevent future deteriorations.

Read this article from a comprehensive knowledge base, updated and supplemented with articles reviewed by scientific committees.

 INTRODUCTION

An existing bridge was designed to provide a certain service. However, due to design and/or execution errors, ageing materials, environmental attacks, aggressive traffic, accidental actions, etc., the bridge may be in disrepair and no longer provide the intended service. It is therefore necessary to repair or even replace it.

In some cases, the load-bearing capacity and geometry of an existing bridge are no longer adapted to the new needs arising from increased traffic and loads. In most cases, this means reinforcing the structure.

The 1 er part of this dossier, [C 7 803] , dealt with "methodology" issues. The second, [C 7 804] , deals with the repair and protection of concrete and reinforcement. The third, [C 7 805] , deals with repair and reinforcement methods using additional reinforcement.

The fourth and final section focuses on steel bridges.

This dossier follows on from [C 7 402] , [C 7 403] ,
