Pampanin, Stefano, Auteur ; Christopoulos, Constantin, Auteur ; Chen, Te-Hsiu, Auteur |The feasibility and efficiency of a seismic retrofit solution for existing reinforced concrete frame systems, designed before the introduction of modern seismic-oriented design codes in the mid 1970s, is conceptually presented and experimentally[...]

Didier Pettinga, Auteur ; Christopoulos, Constantin, Auteur ; Pampanin, Stefano, Auteur |Developments in performance-based seismic design and assessment approaches have emphasized the importance of considering residual deformations. Recent investigations have also led to a proposed direct displacement-based design (DDBD) approach wh[...]

Nabil Mansour, Auteur ; Christopoulos, Constantin, Auteur ; Robert Tremblay, Auteur |In the current design of steel eccentrically braced frames (EBFs), the yielding link is coupled with the floor beam. This often results in oversized link elements, which leads to overdesigned structures and foundations. In addition, the beams ar[...]

Christopoulos, Constantin, Auteur ; Ghanem, Roger G., Auteur |Recognizing the importance of limiting residual deformations that are usually associated with the response of full hysteretic systems under seismic loading, a number of energy dissipating devices and innovative structural systems exhibiting a fu[...]

Hyung-Joon Kim, Auteur ; Christopoulos, Constantin, Auteur |New steel moment-resisting connections that incorporate post-tensioning elements to provide a self-centering capacity and devices to dissipate seismic input energy have recently been proposed and experimentally validated. Experimental studies ha[...]

Jeffrey Erochko, Auteur ; Christopoulos, Constantin, Auteur ; Robert Tremblay, Auteur |A recent study has shown that residual drifts after earthquakes that are greater than 0.5% in buildings may represent a complete loss of the structure from an economic perspective. To study the comparative residual drift response of special mome[...]

Yunlu Shen, Auteur ; Christopoulos, Constantin, Auteur ; Nabil Mansour, Auteur |Although moment resisting frames (MRFs) designed according to the latest seismic codes can provide life safety during a design level earthquake, they are expected to sustain significant damage at flexural yielding locations in the beams. The des[...]

Hyung-Joon Kim, Auteur ; Christopoulos, Constantin, Auteur |Post-tensioned (PT) self-centering moment-resisting frames (MRFs) have recently been developed as an alternative to welded moment frames. The first generation of these systems incorporated yielding energy dissipation mechanisms, whereas more rec[...]
