Behaviour of bamboo scrimber I-beam-box-column connections under static loads
Highlights Eight bamboo scrimber I-beam-to-box-column connections with two types of detailing were tested under static loads. Shear and moment resistances of beam-column connections were obtained from experimental tests. Design methods were evaluated for shear and moment resistances of I-beam-to-box-column connections.
Abstract As an eco-friendly construction material, bamboo scrimber has been increasingly investigated recently in terms of mechanical properties and member behaviour. However, limited test data about connection behaviour are available in published literature. This paper addresses the behaviour of bamboo scrimber I-beam-box-column connections under static loads. Two types of bamboo scrimber beam-column connections were tested, and the number of bolts connecting the beam flange and steel angles or T-stubs was also varied in the experimental programme. The moment resistance, failure mode and deformation capacity were obtained for connections. The shear strength and distortion of panel zones were quantified from experimental data. Comparisons were also made between the calculated shear strengths of panel zones and bamboo scrimbers. Finally, design methods were used to calculate the shear and moment resistances of bamboo scrimber I-beam-box-column connections subjected to static loads. Comparisons between experimental and calculated results suggest that the design methods could evaluate the shear and moment resistance of beams with good accuracy.
