Foundations for the roof support arch for Durban's 2010 World Cup stadium

摘要

The deflection tolerances of a few centimetres under enormous lateral loads presented an interesting design challenge. There remain areas of uncertainty, such as the degree of interlock between adjacent diaphragm wall panels and creep deflections of the foundations under sustained load. To deal with these uncertainties hydraulic jacks will be built into the arch spring-ings and deflections will be carefully monitored during and after construction of the arch. It is hoped that these measurements and their influence on the construction and maintenance of the arch will be discussed in a sequel to this article.
