Early damage to beam‒column joints during an earthquake can cause rapid degradation of structural seismic performance or even collapse of buildings. Installing reinforced concrete (RC) wing walls to ...

Reinforced concrete (RC) beam–column joints are vulnerable to brittle failure under seismic actions due to their limited deformation capacity, posing a threat to the overall safety of RC frames. To ...

The design of structural bridge elements like columns, beam-column joints, and cap beams has changed tremendously over the past 30 years. Many experimental tests have been done in order to determine ...

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, ...
