A naturally buckling brace (NBB) is a steel brace that consists of a high-strength and low-yielding steel channel arranged in parallel with eccentricity acting along the brace length. To enhance the feasibility of NBB fabrication, three connecting design d ...
Concrete-filled steel tube (CFT) columns offer significant advantages over columns made of either steel or concrete alone, such as large energy dissipation and increased strength and stiffness. To further improve the seismic performance of these columns, a ...
Post-earthquake residual deformations often control decisions regarding potential demolition of earthquake-damaged buildings. While residual deformations are typically assumed to be lateral, the column residual axial shortening has similar implications for ...
The Naturally Buckling Brace (NBB) is a steel brace developed by the writers, which consists of a high-strength and low-yielding steel channel arranged in parallel with an intentional eccentricity along the brace length. The NBB deforms with a novel mechan ...

Recent experiments on wide flange steel columns subjected to multi-axial cyclic loading underscore the influence of the member end boundary conditions on strength and stiffness deterioration due to coupling of local and lateral torsional buckling. Field ob ...
The present paper proposes an improved design of conventional buckling braces (CBBs) by introducing intentional eccentricity along the brace length. The proposed brace is named the Brace with Intentional Eccentricity (BIE). Due to the inherent action momen ...

Recent experiments on steel columns under multi-axis cyclic loading suggest that a steel column may experience appreciable axial shortening due to local buckling. Reconnaissance reports from recent earthquakes indicate that a number of embedded column base ...
First-story columns in steel moment resisting frames are subjected to various forms of geometric instabilities during earthquakes. These instabilities have the potential to seriously compromise structural performance, and expedite structural collapse. In t ...
H-SA700 is a type of new ultra-high-strength structural steel that is more environmentally friendly and more suitable for mass production than conventional high-strength steel. The objective of this paper is to contribute to the practical application of CF ...

Conventional buckling braces are the most commonly used steel bracing systems but are characterized by intense local midlength buckling that leads to unstable energy dissipation and finally fracture. Moreover, they are unable to dissipate energy in the eve ...
