Summary
The in-plane shear specimens of full scale CLT panels are tested. From the test results, about the failure behaviour, if there is finger joint near the shear plane, cracks are tended to progress along the joint was confirmed. About the maximum shear unit stress was about 3N/mm2 , and shear stiffness was about 600GPa calculated as the total cross section effective. CLT is composed of longitudinal layers and cross layers. When the CLT is used as shear wall, it is important to understand the in-plane shear performance in order to control the structural performance of wall and joints and the collapse mechanism. Therefore, the in-plane shear specimens of full scale CLT panels are tested.

Summary
Consolidated knowledge of CLT properties under in-plane shear is crucial for typical structural applications such as wall and floor diaphragms, cantilevered CLT walls and CLT used as (deep) beams, in all cases potentially featuring holes or notches. The current technical approvals for CLT products contain differing regulations to determine their load-carrying capacities in-plane. Generally they imply a verification of the torsional stresses in the cross-section of the cross-wise glued elements as well as a verification of the shear stresses proportionally assigned to the boards of the top and cross layers. The basis of theoretical and practical considerations are the following three basic failure scenarios for a CLT-element under in-plane shear: (i) gross-shear (longitudinal shearing in all layers), (ii) net-shear (transverse shearing in all layers in weak direction), and (iii) torsion failure in the gluing interfaces between the layers
