Outline of Final Research Achievements |
Aiming to the application for the large scale timber structures, high strength and high ductility timber bearing wall system is developed. The proposed wall system is consisted multiple X type brace systems toward to the vertical direction in the wall to achieve high strength, and also steel ring connections which are provided to the connections of each braces at the center of the each brace systems for the damage control.The connection element tests were conducted to investigate elasto-plastic behavior of the connection under cyclic reversal load. According to the tests results, the design method of the connection and deformation capacity of the connections are made cleared.Finally, the proposed bearing walls were tested with varying the numbers of the X type brace systems and geometry of the steel ring connection. The tests results show that the proposed bearing wall system can achieve high strength and high deformation capacity.
