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 Bank of America building in Managua,Nicaragua survived after a grand shock of 7.8 grade in 1972. The innovative thinking in design is that the passive control idea was adopted while the bracing between outer frame and inner frame were automatically failed which causes the stiffness of the structure dropped down and frequency decreasing to avoid resonance from the ground motion. 然过于地中心的羊土宣

Innovative thinking in engineering The crossing across Gibraltar Gulf.Two cantilever- suspension bridges spanned 5000m was suggested. The length limit for suspension bridge with conventional materials and technologies is 3000m
Innovative thinking in engineering • The crossing across Gibraltar Gulf. Two cantileversuspension bridges spanned 5000m was suggested. • The length limit for suspension bridge with conventional materials and technologies is 3000m
Innovative thinking in engineering 5km Classical Suspension 1km 3km 1km 2:Hybrid Double-Cantilever Suspension 8 3:Hybrid Cable-Stayed Suspension
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
