A structural engineer is poised to be the first to use steel fibers as structural reinforcing in the lateral-force-resisting system of a concrete-framed high-rise in a seismic zone. The application, ...

New research shows steel I- and T-sections inside concrete beams can offset shear loss from web openings—enhancing safety in ...

A recent series of dynamic tests demonstrates that there are several types and doses of steel-fiber reinforcement that can be used in performance-based seismic design of coupling beams—headers that ...

American Transmission Co. and other utilities are finding high-voltage electrical transmission line and substation upgrade projects place increased structural demand on existing steel-pole support ...
