Abstract

Three connection design properties (dowel embedment strength, slip modulus and screw withdrawal
capacity) were determined for one species of bamboo (Guadua angustifolia Kunth) using experimental
methods adopted from timber engineering. 151 embedment strength and slip modulus tests were undertaken
using smooth dowels with diameters ranging from 3 to 16 mm, whilst 240 screw withdrawal tests
were undertaken using 3.5–5 mm diameter self-tapping screws. Using regression analysis, predictive
equations for the three connection design properties were derived, based on fastener diameter, density
and bamboo wall thickness. Coefficients of determination (R2) ranged from 0.45 to 0.82. The predictive
equations for embedment strength and screw withdrawal were adapted to output characteristic values
and then compared to similar equations derived for timber contained in Eurocode 5, the latter would
seem inappropriate for bamboo
