Abstract

Recent advancements in construction materials have led to an increased interest in Cross-Laminated Timber (CLT) panels as sustainable alternatives to traditional building materials as they are less carbon-intensive and have significant potential for recycling at the end-of-life cycle. The brittle failure mechanisms of CLT can be critical in an extreme loading event and lead to the progressive collapse of the timber building. Combining CLT with high-strength materials in a complementing way could produce a sustainable and resilient hybrid system. This study investigates the performance of CLT panels under dynamic impact loads, focusing on both control panels and hybrid panels strengthened with surface-mounted Carbon Fiber Reinforced Polymer (CFRP) fabric and steel sheets. Commercially available CLT panels were tested using a free-falling drop hammer setup to simulate impact loads of varying intensity. A high-speed data acquisition system recorded impact forces, associated midspan displacements, and strain measurements, while a high-speed camera captured the modes of failure. The experimental setup and methodology enabled a detailed analysis of impact resistance and structural response. Preliminary findings indicate enhanced impact resistance and increased ductility in the CFRP and steel-strengthened CLT panels compared to control panels.
