The French composite: a bridge for Normandy

Article Abstract:

The Pont de Normandie bridge being built in Normandy, France, has a span of 856 meters and would have the longest span in the world when completed in 1994. It is a cable-stayed longitudinally compositebridge where the main steel span is connected to concrete cantilevers resting on concrete towers. This design reduces uplift reaction in the supports and access spans because of the lighter weight of the steel span compared with reinforced concrete. The main span is 624 meters made of orthotropic and isostatic steel deck girders. They are connected to concrete cantilevers that reach 116 meters from the towers.

Metric design: it's real

Article Abstract:

The metric system will be officially implemented in the US starting Jan 1, 1994. The Government Services Administration (GSA) is leading the way in pursuing metrication as it requires contractors to submit bids in metric system for $11 billion worth of projects. The Philadelphia office of the GSA has already changed the American Institute of Architects' Masterspec into the metric systm and is helping other agencies convert their specifications. Mgr Otto Schick says that the metric system should be used in the biggest projects so that construction workers can master the system.

Saving Scotland's busiest bridge

Article Abstract:

Kingston Bridge has been serving Glasgow, Scotland, since 1970. The bridge has been showing signs of deterioration and repair is needed before some of its parts collapse. Condition monitoring systems have been installed to analyze any deformation that may arise during the bridge's strengthening and repair. The first phase of the project is expected to begin in 1996. A planned phase 2 will involve further strengthening of the bridge deck and the replacement of inadequate end bearings and general repair of various concrete members.
