Supplemental Energy Dissipation and Structural Control

Supplemental Energy Dissipation and Structural Control An alternative and often more cost efficient retrofitting strategy compared to base isolation is installation of supplemental energy dissipation devices in structures as a means for passive or active structural control. The objective of Continue reading Supplemental Energy Dissipation and Structural Control

Effects of Seismic Retrofitting on Structural Performance

Effects of Seismic Retrofitting on Structural Performance The seismic retrofit techniques briefly presented in the preceding sections vary in the mechanisms that they decrease the seismic risk of structures. Fig. 8 graphically illustrates these mechanisms by means of their effects Continue reading Effects of Seismic Retrofitting on Structural Performance

SEISMIC RETROFITTING

SEISMIC RETROFITTING A Seismic Retrofit provides existing structures with more resistance to seismic activity due to earthquakes. In buildings, this process typically includes strengthening weak connections found in roof to wall connections, continuity ties, shear walls and the roof diaphragm. Continue reading SEISMIC RETROFITTING
