Jianshe Self-Anchored Cable-Stayed-Suspension Bridge, China
Abstract:Jianshe Bridge is a self-anchored cable-stayed-suspension bridge. This type of bridge has the advantage over earth-anchored cable-stayed-suspension bridges of eliminating traditional earth anchorages. Due to the elimination of earth anchorages, the main cables were anchored at the ends of the stiffening girder. The compressive force offered by the main cables would reduce tendons in concrete stiffening girder and overcame the discontinuity problem of axial force existing in the earth-anchored system. Meanwhile, the anchor block provided vertical pressure to avoid the negative support reaction of side piers. Good mechanical behavior and prominent economic benefit together make it an efficient and elegant solution for moderate and large span bridges.

Structural Engineering International (SEI), the quarterly Journal of IABSE, published since 1991, is the leading international journal of structural engineering dealing with all types of structures and materials. SEI offers its readers a unique blend of short profiles on recent structures, and longer, in-depth technical articles on research, development, design, construction and maintenance. Articles are written by practicing engineers and academia from around the world and reflect the high standards of IABSE. IABSE Peer Review stamps are given to papers that have passed through a highly selective review process and demonstrate a significant contribution to the state of structural engineering knowledge.To recognise contributions of the highest quality, an Outstanding Paper Award is presented each year.
SEI is printed in Switzerland; ISSN 1016-8664; E-ISSN 1683-0350
