oa Civil Engineer in South Africa - The planning, design and analysis of the Bloukrans Bridge

 

Abstract

The Bloukrans Bridge is the largest of three major arch bridges recently constructed on the Garden Route in the Southern Cape. This paper briefly describes the procedures followed in the development of the final structural configuration, the main design considerations, investigations, surveys, the geological evaluation of the site and foundation conditions. Details of the bridge are described and the application and analysis of the main actions and effects for which it was designed are discussed. These include stage-by-stage analysis of the long term effects, non linear analyses under abnormal traffic loading, the application of equivalent static wind loading and dynamic analysis of earthquake action.

Die Bloukransbrug is die grootste van drie vername boogbrüe wat onlangs op die Tuinroete in Suid-Kaapland gebou is. Hierdie referaat beskryf kortliks die prosedures wat gevolg is in die ontwikkeling van die finale strukturele vorm, die hoof ontwerp oorwegings, ondersoeke, opmetings, die geologiese evaluasie van die terrein en fondasietoestande. Besonderhede van die brug word beskryf en die toepassing en ontleding van die hoof belastingsgevalle waarvoor die brug ontwerp is, word bespreek. Dit sluit in die stadiumsgewys ontleding van die langtermyn effekte, die nie-liniêre ontleding van abnormale verkeembelastings, die toepassing van die ekwivalent-statiese windbelasting en dinamiese ontleding van aardbewingsaksie.
