Use of Permanent Magnets to Improve the Seismic Behavior of Light-Framed Structures
Light-framed wood structures generally have satisfied the life safety objective of the current seismic design approach. The main source of energy dissipation in such structures is the inelastic behavior of the connectors connecting framing and sheathing elements. Wood framed structures when …
