Steel braced frames with dual-core SCBs and sandwiched BRBs: Mechanics, modeling and seismic demands
TL;DR: In this article, a steel dual-core self-centering brace (DC-SCB) is developed to have a flag-shaped recentering hysteretic response under cyclic loads.
Journal ArticleDOI
Seismic design and shake table tests of a steel post‐tensioned self‐centering moment frame with a slab accommodating frame expansion
TL;DR: In this paper, a sliding slab is used to minimize restraints to the expansion of a post-tensioned self-centering moment frame and a sliding device is installed between the floor beams and the beams in other bays, wherever the slab is allowed to slide.
Journal ArticleDOI
Finite element models and cyclic behavior of self-centering steel post-tensioned connections with web hourglass pins
TL;DR: In this paper, a self-centering steel post-tensioned connection has been proposed, which uses high-strength steel post tensioned bars to provide selfcentering behavior and steel energy dissipation elements to provide enhanced deformation capacity.
