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 ...

A new method of connecting precast beams and columns will make it possible to quickly repair concrete buildings damaged by extreme events such as earthquakes and hurricanes. The patented technology, ...
