Seismic Performance of Substandard Reinforced Concrete Roof T-joints Retrofitted with Prestressed Steel Plates

International Journal of Concrete Structures and Materials
This study proposes an innovative and practical retrofitting method for reinforced concrete (RC) roof T-joints with substandard structural details. Retrofitting was performed by assembling steel plates with threaded rods on the roof T-joints, which have ...
