Abstract
Classification of Bambusa vulgaris for
structural application was carried out based on the
maximum crushing strength perpendicular and parallel
to the grain of the culm as well as bending moduli of
rupture (MOR) and elasticity (MOE). The findings of
the work showed that the MOR > 70 N/mm2, MOE >
9000 N/mm2 and compression strength > 35 N/mm2.
Following the standard classification of timber species
for structural use in building, B. vulgaris is placed
in group one as the strength properties surpassed the
standard stress limit required for structural application.
The basic density of B. vulgaris falls in the range of
755.22 to 877.23 kg/m3 which is comparable to most
bamboo as well as heavy tropical wood species used in
construction. The overall specific strength properties of
B. vulgaris were somewhat higher than and comparable
to most timber species used in construction.
