TL;DR: In this article, a steel triangular plate added damping and stiffness device (TADAS) was used for earthquake-resistant building construction, and the effects of the ratio of the TADAS element stiffness to that of the bare frame, and of the entire frame yield strength to that associated with the added DBS element on the seismic response of the added stiffness structures were discussed.

TL;DR: In this paper, the axial load behavior of concrete-filled steel tubular (CFT) columns with the width-to-thickness ratios between 40 and 150 was investigated and an effective stiffening scheme was proposed to improve the mechanical properties of square cross-sectional CFT columns.

TL;DR: In this article, a full-scale 3-story 3-bay buckling-restrained braced frame (BRBF) using concrete-filled tube columns was tested in the Taiwan National Center for Research on Earthquake Engineering using networked pseudo-dynamic tests.

TL;DR: In this paper, the force-deformation relationship of a post-tensioned (PT) steel beam-to-column connection constructed with bolted web friction devices (FDs) was investigated.

TL;DR: In this paper, a two-phase experimental program was generated on a full-scale two-story steel plate shear wall with reduced beam section connections and composite floors, to experimentally address the replaceability of infill panels following an earthquake and the seismic behavior of the intermediate beam.
