Physical and mechanical properties of kali (Oxytenanthera nigrociliata), mitinga (Bambusa tulda), bethua (Bamb usa polymorpha) and borak (Bambusa balcooa) have been studied at three different height positions along the culm. These properties were found to vary significantly along the culm height. The moisture content, shrinkage and bending strength decreased as the height increased, but the specific gravity, compressive strength and modulus of elasticity increased with the height. Variations of these properties were also found significant among the species. Borak bamboo exhibited the highest specific gravity and bending strength while mitinga showed the highest value in respect of compressive strength and modulus of elasticity.
