Cable-supported Bridges

Svend Ole Hansen ApS has been a consultant regarding different wind engineering aspects of many cable supported long span bridges: Brusymfonien, the Storebælt and Øresund bridges in Denmark, the Messina Bridge in Italy, the Carquinez Bridge in California, the Hardanger Bridge, the Storda Bridge and the Bømlo Bridge in Norway, the Sunningesund Bridge and the Svinesund Bridge in Sweden, and the Port Tawe Bridge in Wales, UK.

Examples of services provided for some of the bridges are:

Halsafjorden – Norway

Wind engineering aspects of the planned bridge crossing Halsafjord with a main span of 2050 m, which is more than the world’s today longest suspension bridge (2015). The ongoing investigations cover comprehensive wind tunnel testing of the aerodynamic characteristics of the bridge deck in the early design phase including modifications of the bridge deck geometry. Wind buffeting, flutter and vortex-induced vibrations were part of the investigations carried out. Client: Norwegian Public Roads Administration

Forth Replacement Crossing – Scotland

Wind engineering aspects of the Forth Replacement Crossing 4-span cable-stayed bridge with main spans of 650 m. Wind actions of two 322 m long cantilevered bridge decks and significance of neighboring bridge decks during construction stage. Structural vibrations, wind loads. Wind buffeting and flutter were part of the structural vibrations investigated. Theoretical calculations and interpretations of wind tunnel results were carried out. Client: Rambøll

Jambi Bridge – Indonesia

Wind engineering aspects of Jambi Bridge. A three span cable-stayed composite foot bridge with a main span of 154 m. Wind tunnel tests for determination of structural vibrations and wind loads were carried out. Wind buffeting, vortex shedding and flutter were part of the structural vibrations investigated. Client: PT. FKA Global

Messina Bridge – Italy

Wind engineering aspects of the Messina suspension bridge with a main span of 3300 m. Structural vibrations, wind load, wind-induced traffic accidents and estimation of extreme winds at the Messina site. Wind buffeting, flutter and vortex-induced vibrations were part of the structural vibrations investigated. Theoretical calculations and interpretation of wind tunnel test results were carried out. Client: Steinman Boynton Gronquist & Birdsall (today Parsons Corporation)

Storebælt (the Great Belt) Bridge – Denmark

Wind engineering aspects of the Storebælt suspension bridge with a main span of 1624 m. Structural vibrations, wind load, wind-induced traffic accidents and the extreme estimation of the extreme winds at the Storebælt site. Wind buffeting, flutter and vortex-induced vibrations were part of the structural vibrations investigated. Theoretical calculations and interpretation of wind tunnel test results were carried out. Clients: Steinman Boynton Gronquist & Birdsall (today Parsons Corporation) and A/S Storebæltsforbindelsen (today A/S Storebælt)

Øresund Bridge – Denmark/Sweden

For and in cooperation with Rambøll: Wind engineering aspects of the Øresund cable-stayed bridge. Structural safety, structural vibrations, wind load, wind-induced traffic accidents, estimation of the extreme winds at the Øresund site and rain-wind induced vibrations of the cables. Wind buffeting, flutter and vortex-induced vibrations were part of the structural vibrations investigated. Theoretical calculations and interpretation of wind tunnel test results were carried out. Client: Øresund Link Consultants (Rambøll)

Hardanger Bridge – Norway

Wind engineering aspects of the Hardanger suspension bridge with a main span of approx. 1300 m. Quality assurance of the extensive wind engineering studies carried out in the 90’ties. Investigations from 2006 to 2008 covered comprehensive wind tunnel testing of the aerodynamic characteristics of the bridge deck including improvements of the structure by aerodynamic means. Wind buffeting, flutter and vortex-induced vibrations were part of the investigations carried out. Time domain analyses of buffeting and flutter vibrations.
