This book contains the invited contributions to the 1993 Henderson Colloquium organised by the British Group of IABSE (International Association for Bridge and Structural Engineering). It provides an international review of new techniques of designing and constructing joint-free bridges - an approach which is rapidly being developed and used in many parts of the world. "an extremely important part of the very sparse literature on continuous bridges. It is a must for all bridge design offices, and dare I suggest it would make good reading for graduates preparing for Professional Review...I can thoroughly recommend this collection of very important papers for not only those interested in but also those who have to design, maintain or strengthen continuous bridges of any type" - Proc.Instn.Civ.Engrs.Structs & Bldgs.
