| Popis: | The paper presents an investigation on the influence of geometrical dimensions of lintel beam, wall segment, lamella layup and the mechanical behaviour of hold-down on the inelastic behaviour of the CLT shearwall assembly. Five full-scale shearwalls were tested and used in the validation of a proposed numerical model. The verification of failure in the CLT panels is done using the RVSE model and the comparison between the analytical results and those obtained from tested was done using the Equivalent Energy Elastic Plastic method. The parametric study of the behaviour of the walls in the inelastic range demonstrated the important effect of the lintel beam, wall segment slenderness as well as the hold-down stiffness on the mechanical and global kinematic behaviour of the wall. It was observed that the kinematic modes can change when the walls are loaded beyond their elasticity limit. The failure mode and the global ductility were also found to be dependent on the hold-down configurations, particularly for walls with door openings. |
