Resumo<p>The paper presents studies on buckling of complex, unusual, innovative and iconic built steel structures for which the author has been responsible. The work on City of Manchester Stadium focuses on pin-ended cable-stayed masts up to 40m long carrying 12 MN. Masts at Barcelona Bullring were of similar size, but of more complexity: being formed into portals providing overall stability to a 200m diameter roof. The work done on the BA London Eye was highly innovative and complex looking at the buckling of the 150m diameter bicycle wheel structure. The roof of the London Stadium has some similarities to the bicycle wheel of BA London Eye, but is restrained out of plane and thus more resilient with no global buckling modes. The stadium is one of a number undertaken by Buro Happold including the award-winning Aviva Stadium. The final project is Infinity Footbridge for which the author led the early buckling studies.</p>
