Mechanical evaluation on BFRP laminated bamboo lumber columns under eccentric compression

Abstract

Bamboo has been studied and utilized quite significantly in recent years because of its advantages such as short growth period, good appearance, environmental protection and superior mechanical properties. Bamboo is processed into profiles to address inherent issues with size limitation and self-defects and use of BFRP can enhance the mechanical properties of bamboo for widespread application. In this paper, the mechanical properties of BFRP strengthened chamfered laminated bamboo lumber (LBL) columns with four eccentricity e0 of 30 mm, 60 mm, 90 mm, and 120 mm were tested. The strengthening effect of BFRP on the performance of LBL columns subjected to eccentric loading was compared with the specimens without any reinforcement. Several analytical models to capture the mechanical performance of BFRP reinforced LBL columns with different eccentricities have been proposed in the current study.
