| Outline of Final Research Achievements |
For improvement of deformation capacity of angle-shaped steel braces and suppression of their deterioration behavior, a reinforcement method was investigated. In that method, the same steel angles as the brace member are welded at the brace-ends for both reinforcements of compression and connection behavior. Loading tests under compression, tension and repeated loads were conducted. The finite element analyses were also conducted. The test and analysis results revealed efficacy of the proposed reinforcement method. Furthermore, effects of the out-of-plane stiffness of gusset plates were examined. Stiffening methods of bolted connections with steel member assemblies were also examined for connecting the reinforcement members to the existing building frames.
