Abstract

Abstract This study echoes the rising demand for bio-based material in concrete composite structures in the race to accelerate carbon neutrality in construction. Noticing that most previous studies are focused on straight timber or engineered bamboo-to-concrete composite beams, this study focuses on: 1) developing unique and practical curved laminated bamboo-concrete (LBC) composite beams; 2) experimentally investigating and comparing the structural performances of the curved and straight LBC composite beams; 3) developing a novel and proper in-member interface shear slip calibration method that captures the longitudinal after-slip strain redistribution, validated by stain gauge measurements. This study also highlights the interlayer shear bonding strength of laminated bamboo as the thresholding parameter that determines the composite beams' overall flexural strength, evidenced by detailed failure mode analysis. The proposed interface shear slip calibration method can be extended to the other types of shear connectors such as screws, shear plates, etc.
