Abstract

Cross laminated bamboo and timber (CLBT) is a new type of bamboo and timber composite materials used in engineering activities. Similar to cross-laminated timber (CLT), CLBT exhibits the dimensional flexibility for diverse structural applications This study investigates the dynamic properties of CLBT floor slabs through experimental and theoretical analysis of natural frequencies and damping ratios. Modal testing methods, including impact hammer excitation and accelerometer-based vibration measurement, were employed to determine the first three bending-mode natural frequencies and associated damping characteristics. Experimental results were validated against theoretical predictions derived from the fundamental beam vibration formula, and the measured natural frequencies showed strong agreement with calculations. All specimens exhibited natural frequencies exceeding 8 Hz with damping ratios less than 3%. These findings provide critical references for vibration-controlled design of CLBT structures.
