Innovative thinking in engineering .The first pre-stressed RC structure was the grandstand of Caracas,Venezuela.1954 ● The cantilever was 27m and the shell thickness was just 7.5cm. The quality of pre-stressed cantilever shell structure is so reliable that T.Y.tested it by jumping at the cantilever tip in 1984,it performed safe and stable

Innovative thinking in engineering • The alternative of 14km route crossing the gulf was adopted, three piers were built with 450m pile foundation • The mixed type Gibraltar bridge uses suspension bridge spanned 3000m in the middle and a cantilever for both 1000m to support the cable in the middle by inclined struts at the both sides
Innovative thinking in engineering Ling-tie was designed for the crossing of Yong river in Nanning,Guangxi China. A pair of inclined steel arch formed a saddle support the curved 300m steel box girder with 6-lanes traffic. The approaches are the post-tensioned RC box girders on RC piers. Both sound structural features as well as the aesthetics uniqueness made the bridge a landmark of the city
