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 ...

Dapped‐end beams, featuring a reduced or notched termination, are widely implemented in reinforced concrete structures, particularly in precast systems where construction efficiency is paramount. The ...

An immense concrete bridge beam took up both lanes of Route 61 south in Schuylkill Haven on Thursday morning on its way to Bucks County. Manufactured at Northeast Prestressed Products in Cressona, the ...

Many of the 3D printed houses and structures we’ve seen use concrete and are — frankly — a little underwhelming. Making big squares out of concrete isn’t that hard and while we are sure there is some ...

Insulated suspended flooring systems can be used in place of conventional beam-and-block to meet higher energy performance standards. This CPD, sponsored by Springvale, outlines the design ...
