Long Span, Prestressed Concrete Bridge Construction

a rigid frame system. Modern prestressed concrete bridges give an impression of slenderness and open space. The driver doesn't feel as if he's going through a. tunnel. For long-span concrete bridges, pre­ stressing turned out to be the answer in design and construction. Engineers should design for continuity, because it has tremendous advantages.

Effects of Live Load on the Deflection of Long-Span PC ...

08-01-2015  Down-deflection is one of the most common diseases of long-span prestressed concrete (PC) bridge. According to relevant design codes and deflection calculation methods, effects of live load were not explicitly considered. Thus, it is necessary to analyze the live load effects on bridge down-deflection in detail. In this paper, the whole construction process of a long-span PC continuous ridge ...
