Highlights A new type of bamboo and timber composite material (CLBT) was developed by bidirectionally assembling and gluing bamboo-based glulam (glubam) and timber. CLBT beams have similar and even larger bending stiffness and capacity compared with CLT beams. In addition to the experimental method, advanced analytical models are also applied to investigate the flexural response of CLBT beams. Some optimal patterns are provided for the design of CLBT beams to achieve a favorable flexural performance.
Abstract The flexural behavior of cross laminated bamboo and timber (CLBT) and cross laminated timber (CLT) beams are studied to explore the potential of using glued laminated bamboo (glubam) in CLT panels to obtain similar or even better mechanical performance and other constructional and environmental merits. The 4-point bending experiments were conducted for full-scale model CLBT and CLT beams, assisted with using deformation instrumentations including the digital image correlation method (DICM) and conventional methods (LVDT and strain gauges). All the experimental results show that the CLBT beams have the similar even better bending stiffness and capacity than corresponding CLT beams, and the advantage is more significant for beams under in-plane bending condition. Analytical models based on two-dimensional (2D) elasticity theory are also applied to predict the flexural response of CLBT beams. The accuracy of the proposed analytical models can be verified by comparing the results with experimental results. Some parametric studies for CLBT beams with different combination configurations of glubam and wood layers are also conducted to provide several design suggestions to achieve favorite flexural performance for this type of cross laminated bamboo and timber beams.
