EWECS柱の耐火性能

This research is to develop a new wooden hybrid column composed of laminated wood and concrete-steel. This hybrid column is called the EWECS column. EWECS column is made by covering steel with concrete and arranging laminated timber on the outside. However, this EWECS column uses laminated timber for the outer shell, but its fire resistance performance has not been clarified. Therefore, a fire test was conducted on a full size EWECS column specimen. As a result, it was confirmed that the EWECS column covered in this study has fire resistance performance of 2 hours as a column member.
