We developed a timber shear wall in steel frame structure and estimated the required performances to be introduced in the 5 storey building. Firstly, we designed the shear walls of this system to satisfy the requirements and conducted the full-scale shear tests to grasp the characteristics of the failure behaviors and the actual properties of the walls. Secondly, we proposed the analytical model and compared to the test results to verify the possibility for predicting them. It was concluded that the walls adopting Cross-Laminated-Timber could achieve the required performances and their mechanical behaviors could be predicted fairly precisely.
