STUDY ON THE OPENING REDUCTION COEFFICIENT OF CLT PANEL WITH OPENING

Abstract

In order to propose the opening reduction coefficient of the 5layer 5ply CLT wall panel, in-plane shear tests of the CLT wall panel with openings were tested.
The knowledges are (1) the maximum shear unit stress of the CLT wall with opening excluding the opening area is from 2.0 to 2.2 N/mm², (2) the relationship between the opening coefficient of the CLT wall and the stress ratio, the relationship of F=ϒ/(10-9ϒ) (at the real deformation angle) and F=ϒ/(5-4ϒ) (at the apparent deformation angle) are the best to predict these relationships.
