Seismic Retrofitting RC Structures with Precast Prestressed Concrete Braces- ABAQUS FEA Modeling

Multi-stage Performance Upgrade of Steel Moment Frames by Post-tension Connections

“…Various approaches have been proposed to model the PT connection-based moment frame structures. These solutions include finite element modeling [18][19][20] and modeling with introducing post-tension members by Figure 2. Erection details of retrofitting moment frame with welded connections using post-tensioned elements the spring element [21].…”
