Abstract

Abstract

The mechanical properties of bolts and hollow rivet connectors in engineering bamboo structures were studied to provide theoretical and technical support for applying the above connectors in glubam designs. The nominal yield strength and a plastic bending moment of grade 4.8 and 8.8 bolts, hollow rivets of different diameters were tested by using the three-point bending method. The semi-hole method tested the embedment strength of different types of bamboo in the main-fiber and the less-fiber directions. Monotonic and hysteretic tests tested the bearing capacity, stiffness, and ductility of the bamboo-steel-bamboo connections. The bearing capacity values measured by the test were compared with the bearing capacity estimation values through corresponding failure modes, and the appropriate estimation formula was determined. The experimental results showed that bamboo was a brittle engineering material with pronounced anisotropy. The yield failure of steel and the shear failure of bamboo were the main failure modes of bamboo-steel-bamboo connections studied herein. Through proper connector design and cross-laminated strips, the above connectors could form a ductile failure mode dominated by steel yielding. Through the corresponding yield model, the bearing capacity of the bamboo-steel-bamboo connection could be estimated.
