Review and Prospect of Research on FRP-Reinforced Glulam Bending Members

Abstract:

This paper provides a comprehensive review of the research on fiber-reinforced polymer（FRP） reinforced glulam bending members， systematically summarizes the existing reinforcing technologies， and elaborates on the influencing factors and analytical methods of the interfacial bond performance， the bending performance， and the creep performance of FRP-reinforced glulam beams. The findings demonstrate that FRP reinforcing technologies effectively utilize the strength of wood in glulam bending members， enhance their bending capacity， control bending deformation， and improve the brittle failure mode. Considering the constraints of FRP-reinforced glulam bending members in engineering applications， it also proposes key issues that need to be addressed in the research on the prestressing technologies， long-term performance， fire resistance， and reliability.
