Stronger Longer
Like many older concrete bridges, the Sierrita de la Cruz Creek Bridge, a 1957 crossing near Amarillo, Texas, suffered from concrete deterioration. When the Texas Department of Transportation...
Maintenance of Diaphragm-Girder Connections
Fatigue cracking at diaphragm-girder connections and at similar connections of cross-frames and floorbeams have been common in steel highway bridges for the past 20 or 30 years. Fatigue...
Update of Serviceability Design Considerations for Low-Rise Steel Buildings
In 1990, the American Institute of Steel Construction published Servicability Design Considerations for Low-Rise Buildings by James M. Fisher and Michael A. West. This document was published...
Evolution of Composite Floor Systems in the United States
Composite floor systems, which combine structural steel beams with a cast-in-place concrete slab, have grown in popularity in the U.S. during the past 40 years. In most early applications,...
