Current and Future Trends in Bridge Design, Construction and Maintenance


Book Description

The major expansion of transport networks in the twentieth century has been accompanied by extensive bridge construction. At the end of the century, the field of bridge engineering continues to grow and develop. Recent years have seen the construction of revolutionary new bridges, advances in materials and construction techniques and the development of international codes and standards aimed at producing more durable and reliable structures.




A Contribution to Moving Force Identification in Bridge Dynamics


Book Description

The knowledge of the real forces acting on a structure are of great importance in the condition assessment process of existing structures. In this sense, this work provides a novel approach for identification of dynamic moving forces acting on a bridge structure. It seeks to find the optimal time dependent force values that minimize the difference between the computed and measured displacement and acceleration time histories for a limited number of sensor locations. The work also presents extensive experimental investigations of the developed method on real structures in operation, which consistently show that it can be successfully used on a wide range of applications: from small structures excited by rather low pedestrian forces up to the "heavy category" of a complete train passing a railway bridge. In this context, a set of particularities and limitations arising in the practical application of the method on real structures are also discussed.

Bridge Management 5


Book Description

Contains over eighty papers covering the fields of bridge management systems, inspection methods, structural assessment and maintenance strategies; together with the reliability and risk management techniques. This book is useful for bridge owners and engineers engaged in bridge design, assessment, repair and strengthening. The last five years have seen the art of bridge management develop into a mature subject. Bridge owners and engineers recognise the importance of implementing fully operational bridge management strategies to ensure that all road and rail bridges remain functional for as long as possible. Bridge structures form a major part of the vast financial investment in infrastructure and consequently their careful management involving structural appraisal, repair and strengthening is of paramount importance. Factors such as the chosen repair method can influence how often and for how long a bridge structure is out of operation. This in turn, determines the ensuing traffic and/or rail delay costs and also any resulting increase in traffic pollution.The 5th volume on Bridge Management contains over eighty papers which span the fields of bridge management systems, inspection methods, structural assessment and maintenance strategies; together with the latest reliability and risk management techniques. Almost all of these papers have been presented at the Fifth International Conference on Bridge Management held at the University of Surrey in Guildford, UK in 2005. The book will prove to be a very useful reference manual for all bridge owners and engineers engaged in bridge design, assessment, repair and strengthening. The volume is also recommended as a reference text for other professionals who are concerned with care of the environment and the minimisation of pollution due to traffic delays and non-conventional repair and protection methods.
