This study investigates the deformation behavior of reinforced fresh bamboo subjected to staticcompressive loading condition. Crushing strength test was performed using Uniaxial Compression Machine with maximum loading capacity of 1500 kN. The data is plotted as strength to weight ratio versus height, strength to volume ratio versus height, failure stress versus height, load versus time of failure and load to height ratio versus time of failure. Result shows that increase in height of the fresh reinforced bamboo increases the strength and vice versa. The moisture content also has significant influence on the strength of the fresh reinforced bamboo. The moisture content reduced the strength of the fresh reinforced bamboo by 21.8%. This percentage is really significant in structural analysis since it can cause catastrophic failure to structures. Concrete is significant in reinforcing bamboo structures for a better strength. The crushing stresses for fresh reinforced bamboo of heights 250, 210,170, 130 and 90 mm were found to be 26.09, 25.52, 24.85, 21.97, 21.86 Mpa, respectively. The failure stress of the bamboo is about say 1.26 M times the weight of the bamboo per m^2. The specific compressive strength which explains the bending moment per kilogram of the bamboo specimen also increases with increases in height. Failure stress to weight ratio decreases with increases with the height of the bamboo. Strength to volume ratio also decreases with increases with the height from the bamboo.
