The composite action of cross-laminated timber rib panels at elevated temperatures
Abstract
In the frame of an ongoing research project, the fire behaviour and fire resistance of CLT rib panels are studied. The floor system consists of cross-laminated timber (CLT) plates rigidly bonded to glued-laminated timber ribs by means of screw-press gluing using a one-component polyurethane adhesive. The experimental programme comprised reference tests and fire tests for fire resistances up to 120 min. In addition to the reference tests, shear tests of the bondline between CLT plate and glulam rib were performed at normal temperature. Further knowledge of the bondline’s behaviour was required for a wider range of temperatures. Therefore, shear tests of the bondline were performed at elevated temperatures. This paper focuses on the analysis of the cross-sections’ composite action in fire and under elevated temperatures. The fire resistance tests confirmed the assumption that the effect of the composite action was maintained in fire. The shear tests at normal temperature emphasized the required quality control as basic requirement for the composite action. The shear tests at elevated temperatures confirmed the bondline’s thermal stability up to 220°C. The residual shear strength at elevated temperatures were used to draw conclusions for the bondline’s performance under ISO-standard fire exposure. The bondline was determined to be intact in fire.
