【 摘 要 】

The paper describes usage of a composite rebar in applications with reduction of thermal bridges, with emphasis on compression reinforcement. The paper focuses on several areas: The mechanical tests, resulting mechanical properties and temperature behaviour of compressed reinforcement. Compression elements with short fibres of length 6 and 50 mm or long fibres and with or without a rebar were tested. The comparison between materials and results of behaviour of a simple compressed rebar at elevated temperatures is shown. The critical temperature of usage FRP material as a compression element was found.
