The correlation between Ampel bamboo (Bambusa vulgaris) dimension and geometry with its modulus of elasticity

Abstract

Traditionally, Indonesian people are used to using bamboo as construction material. Whole bamboo stems (bamboo culm) which is round and hollow, has several segments and tapered. Regarding the development of bamboo utilization for construction material, testing standards and code of practices are needed to ensure the users safety. The quality of bamboo construction can be improved by using a stress grading system. Therefore, this research is needed to obtain the grading variable that influences the modulus of elasticity of Ampel bamboo (Bambusa vulgaris). Based on analysis of their variable, bamboo's dimension and geometry are not affecting modulus elasticity value. This result shows that the further research for grading system is required to obtain identify characteristics parameter of Bambusa vulgaris that correlate with the modulus of elasticity.
