ANCHORING OF CROSS-LAMINATED TIMBER SHEAR WALLS

This paper presents a validated finite element model of a cross-laminated timber (CLT) wall-to-floor connection and compares its predictions with results from a full-scale shear wall test. The CLT wall and floor panels are modelled as orthotropic shell elements, while the discrete connectors (tension anchors, angle brackets and the screw connection between floor panels) are represented by line hinges with nonlinear load-slip relationships.These relationships are derived from dedicated component tests on tension anchors, shear brackets and screw head embedment. The model is analysed in nonlinear static steps corresponding to the experimental loading sequence. Vertical slip along the wall-to-floor interfaces and the global lateral load-displacement response of the wall are extracted and compared with measurements. The results show that the simplified line-hinge representation reproduces both the global stiffness and the local deformation pattern in the joints with satisfactory accuracy for design-oriented analyses.
