Learn the history of the incremental launching method for steel, prestressed-concrete, and prestressed-composite bridges with steel corrugated-plate webs.

Although thermal warping may adversely affect the durability of precast segmental bridges, AASHTO standards and the ASBI Construction Practices Handbook neglect this effect.

Download this publication of Dr. Rosignoli (2001, ACI Concrete International) on prestressed composite space-frame solutions for high-efficiency concrete bridges.

Streamlined edge girders and two planes of stay cables offer multiple advantages over twin side-winged box girders suspended by delta-frames from a central plane of cables.

Overhead gantries provide unrivalled versatility in light-rail transit bridges, urban bridges in median, marine operations, and other conditions of reduced clearance under the bridge.

The underslung gantries are the simplest, least expensive, and often most efficient self-launching machines for span-by-span erection of precast segmental bridges.

The level of sophistication of new-generation bridge construction machines requires adequate technical culture to bridge owners, designers and constructors.

The design of long-span bridges requires wind tunnel testing. Sectional models investigate buffeting, flutter, vortex shedding and galloping. Aeroelastic models determine aerodynamic derivatives and flutter speed.
