Outstanding Paper Award

The Outstanding Paper Award is remitted each year to the author(s) of a paper published in the preceding year’s issues of the IABSE quarterly Journal Structural Engineering International (SEI), encouraging and rewarding contributions of the highest quality. The Award is presented in the categories ‘Scientific Paper’ and ‘Technical Report’. The Awards will be presented to the Authors on occasion of the Annual Meetings and 37th IABSE Symposium to be held in Madrid from August 31-September 5, 2014.

Category ‘Scientific Paper’: “Vibration Mechanisms and Controls of Long-Span Bridges: A Review" by Yozo Fujino and Dionysius Siringoringo; Japan; SEI 3/2013, (August) pp. 248-268.

Dynamic performance is an important consideration in long-span bridge design. Owing to its flexibility and low damping, various types of vibration from different sources of excitation could occur during the lifetime of a long-span bridge. This paper reviews important studies and developments on long-span bridge vibration mechanism an d control under wind, seismic,traffic and human-motion excitations. Types of vibration commonly observed on the long-span bridge are discussed from the viewpoint of structure engineering. Discussion for each subject is commenced by describing the vibration mechanism followed by the survey on observed phenomena in many long-spa n bridges associated with the type of vibration. The paper also describes the engineering solutions adopted as countermeasures for each type of bridge vibration problem.

Category ‘Technical Paper’: “Rehabilitation of the Suspension Bridge over Zambezi River in Mozambique” by António Reis and Claudio Baptista; Portugal; SEI 1/2013 (February), pp. 89-93.

The suspension bridge across the Zambezi River at Tete in Mozambique was built between 1965 and 1970. It is a multi-span suspension bridge with a total length of 720 m and an unique structural scheme. Inspections during 1999 and 2005 identified three major problems: unbalanced load on hanger system with major misalignments in deck geometry, hanger failure by fatigue and corrosion, and damage to the concrete caused by excessive rotations of main transverse beams suspended by hangers. This paper describes the most important design options and solutions put forth for the rehabilitation of the bridge and for extending its lifespan under increasing traffic loading.

The International Association for Bridge and Structural Engineering (IABSE) was founded in 1929, IABSE and deals with all aspects of planning, design, construction, maintenance and repair of civil engineering structures. To fulfil its mission, IABSE organises conferences and publishes a quarterly journal, Structural Engineering International, as well as books and reports. The Association has a number of technical groups and presents awards in recognition of outstanding contributions in the domain of structural engineering.
