| Outline of Final Research Achievements |
This research includes two experimental works for developing the earthquake resistant wall with clack preventing capacity. One is Concrete Filled Steel Tubular (CFT) short columns which are used in energy dissipating structural walls (EDSWCs) proposed by Sakino in 2004. The other is new proposal of the earthquake resistant wall. Tests were carried out on twenty-eight specimens of the square and rectangular CFT columns with shear span ratio under 1.0. Also ten wall specimens were tested. They were subjected to cyclic lateral force under constant axial force. CFT specimens showed ductile behaviors even though they failed in shear before flexural yielding. The load vs. deformation relations of wall specimens showed stable manner without apparent cracks.
