Strengthening of CLT-panels with fiber reinforced polymers
Abstract
Strengthening of CLT-panels with fiber reinforced polymers
Incoming article date: 26.05.2023High-rise buildings with CLT (cross-laminated timber) load bearing structures are being more actively developed in many countries. CLT-panels are lightweight, ecological and easy to assemble. In the article types of strengthening of three-layers and five-layers CLT-panels with carbon, basalt and flax fiber reinforced polymers (FRP) are considered. They can be used for panels under exploitation to reduce influence of defects and increase load bearing capacity and stiffness or in the production stage to reduce thickness and weigth of constructions. Known works of international authors are analyzed. Bending behaviour of externally reinforced CLT-panels is described. Areas that deserve further investigation are determined. They include investigation of different composite materials and wood types used for CLT-panels' production.
