| Outline of Final Research Achievements |
Firstly, cyclic loading tests focusing on the residual out-of-plane deformation and the leg opening of single angle brace were conducted. The major findings obtained from the test are summarized as follows: (1) the maximum story drift angle and the maximum elongation of the brace can be estimated by using the residual out-of-plane deformation; (2) cumulative damage due to cyclic loading can be estimated by the length of the leg opening of its cross section.
And, cyclic loading tests focusing on the residual out-of-plane deformation in the local buckling region of steel column were conducted. The major findings obtained from the test are summarized as follows: (1) the out-of-plane deformation in local buckling region was strongly related with the residual strength deteriorated due to the local buckling; (2) the rotation angle of column after deterioration is able to be converted to the out-of-plane deformation by a 3-hinge deformation model of the local buckling.
