Abstract
The natural round bamboo is a kind of ecological building material with many excellent physical and mechanical characteristics, such as fast growth, high strength and good environmental performance. However, the natural round bamboos were barely used for its worse durability and easiness to crack compared other bamboo productions after secondary operation. In order to improve the safety and durability of the round bamboo structure, the axial compression test of the GFRP (glass fiber-reinforced polymer) and/or mortar reinforcing cracked bamboo was conducted. The 20 cm tall round bamboo column specimens were divided into five categories: the first without cracks and reinforcement, the second with cracks but without reinforcement, the third with cracks and full GFRP reinforcement, the forth with cracks and fulfil of cement motrar, and the last with cracks and reinforced using both GFRP and cement mortar. The bearing capacity and the failure modes were observed and studied. It was found that the composite reinforcement of GFRP and mortar could significantly increase the bearing capacity of the cracked round bamboos, and avoid brittle failure through improving the ductility of the specimens.

Summary
Bamboo is a kind of ecological building material for its physical and mechanical characteristics, such as fast growth, light weight, high strength, and good environmental performance [1,2,3,4] It was barely used for its worse durability and easiness to crack compared other bamboo productions after secondary operation [5]. Fiber-reinforced polymer (FRP) has been widely applied to improve the bearing capacity and ductility of concrete and metallic structures due to their high strengths, low weights, anti-corrosion capability and easy forming characteristics. This method is typically used to reinforce columns via wrapping to provide confinement. Huang [7] studied the mechanical properties of bamboo reinforced with CFRP or wire in different ways, using experimental research analysis method, to find out the better strengthening methods, which can provide reference for engineering applications
