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 ...

Gustavo J. Parra-Montesinos is coming to the rescue of concrete-frame designers and contractors in earthquake country, long bedeviled by rebar-congested coupling beams that span openings in seismic ...

When project teams debate the relative merits of steel and concrete building frames, design quality is seldom the only criterion. Construction time and cost are usually paramount considerations. The ...

A ground beam is a reinforced concrete beam for supporting walls at ground level. Its purpose is to link the piles together and provide a platform for further superstructure construction. A beam is a ...
