Abstract
AbstractThe feasibility of incorporating semi‐active resettable springs (SRSs) to mitigate torsional response of structures is investigated. The effectiveness and robustness of the SRSs in reducing seismic demand was demonstrated on a spectrum of building properties idealized with one‐story asymmetric structures. The effects of the SRSs on the edge displacements were analyzed and several system parameters were identified that significantly effect the edge displacements. Two approaches based on geometric constraints and modal analysis are proposed to determine the proper distribution of the SRSs to minimize edge displacements. Limitations and guidelines on implementation are also provided.
