Tampico bridge
Encyclopedia
The Tampico Bridge is a vehicular cable-stayed bridge
in Mexico
, located on the Pánuco River
in the city of Tampico, Tamaulipas, near to the Gulf of Mexico
. The bridge has been in service since 1988 and was designed by Professor Modesto Armijo from COMEC, a Mexican engineering company. It was designed to withstand the severe hurricanes of the Gulf of Mexico
. It connects the states of Tamaulipas
and Veracruz
.
The bridge uses an orthotropic
steel deck girder for a central section of the 360 m long main span, while the rest of the main span and the short lateral spans are a prestressed concrete
girder. Both steel and concrete deck girders have the same external shape. This original principle was later used at the French Normandy cable-stayed bridge (756 m main span).
The dynamic analysis of the bridge under turbulent cyclonic winds, as well as the revision of the structural project, and the geometry plus stress control of the bridge during erection, were achieved by Alain Chauvin from Sogelerg, using the French
"Scanner" computer program.

Orthotropic deck
An orthotropic bridge or orthotropic deck is one whose deck typically comprises a structural steel deck plate stiffened either longitudinally or transversely, or in both directions. This allows the deck both to directly bear vehicular loads and to contribute to the bridge structure's overall...

Prestressed concrete is a method for overcoming concrete's natural weakness in tension. It can be used to produce beams, floors or bridges with a longer span than is practical with ordinary reinforced concrete...
