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 [...]

The Naturally Buckling Brace (NBB) is a steel brace developed by the writers, which consists of a high-strength and lowyielding steel channel arranged in parallel with an [...]

The present paper proposes an improved design of conventional buckling braces (CBBs) by introducing intentional eccentricity along the brace length. The proposed brace is [...]

Many existing structures in seismic vulnerable areas require seismic upgrading to prevent the collapse in case of extreme earthquakes. This paper proposes an approach bas [...]

This paper proposes a rocking system to limit the residual deformation of moment-resisting frames in order to improve the immediate occupancy performance and reduce the r [...]

Brief histories of the establishment of NEES and E-Defense are presented, followed by a summary of the preparation, initiation, and status of the NEES/E-Defense collabora [...]

This paper introduces a large scale shake table experimental program on bridge structures using E-Defense. The program was formulated as one of the US-Japan cooperative r [...]

This research focuses on the nonstructural components in high-rise buildings subjected to large seismic responses. A serious of large-scale shaking table tests is conduct [...]

A review of permissible residual deformation levels is undertaken in light of the increased interest in performance-based seismic design and self-centering systems. Permi [...]
