Integral bridges
A fundamental approach to the time-temperature loading problem
George L. England, David I. Bush, Neil C.M. Tsang
Résumé
The growing importance of integral bridges has highlighted the need for more information and guidance to assist in improving bridge design. This book presents the results of research commissioned by the Highways Agency into the thermally induced soil/structure interaction created by environmental temperature changes and the associated cyclical displacements imposed on the granular backfill of bridge abutments. lt:
- develops a better theoretical understanding of temperature-induced cyclic displacements; in particular the strain ratcheting in backfill soil in contact with a 'stiff 'structure
- identifies the governing soil parameters and examines their influence
- develops numerical modelling procedures to predict soil behaviour
- identifies and quantifies the controlling features of bridge structures relevant to the interaction problem
