ABSTRACT

This paper focuses on how environmental loads should be taken into account in the design and construction of durable integral bridges with reference to South African conditions. Specific reference will be made to the Van Zylspruit River Bridge, a 90m long, fully integral bridge located on the South African National Roads Agency SOC Ltd (SANRAL) National Route N1. The bridge has been extensively instrumented and since the end of 2015 the structural response to the environmental conditions have been recorded. Some of the trends observed are discussed in this paper.
