Abstract
The purpose of this research/thesis is to investigate and define (for the first time) the mechanical properties of the two natively growing and primarily utilized bamboo species in Nepal, namely: Ban/Dhanu baans (Bambusa balcooa) and Maal baans (Bambusa nutans). Here bamboo related ISO standards and ASTM D 5764 – 97a (2002) were followed for conducting material tests and analysis. Shaft-bolt arrangement of connections were tested according to the preexisting details used previously in construction in Nepal. While Gusset plate arrangement of connection were designed using material properties of B. balcooa with intent of IIIs or IV mode of failure according to yield equations from TR 12 of American Wood Council, then tested. These two typologies of connection were tested from both species, each having two variants namely, confined (with hose-clamps) and unconfined (without hose-clamps). Measurement and Test data were analyzed to compute geometrical imperfection in bamboo culms, characteristic values of mechanical strengths and interpretation of connection tests.
