LATERAL LOAD RESISTANCE OF PARALLEL BAMBOO STRAND PANEL-TO-METAL SINGLE-BOLT CONNECTIONS – PART I: YIELD MODEL
Keywords:Single shear bolted connections, lateral load resistance, parallel strand bamboo panels, bolt bending moment, bolt-bearing strength, European Yield Model, yield theory.
The lateral load resistance behavior of single-shear unconstrained metal-to-parellel bamboo strand panel (PBSP) single-bolt connections was investigated. The connection consisted of a PSBP main member fastened to a metal plate as a side member using a 6-mm diameter bolt without a nut or washer used. The mechanics-based approach waas used to evaluate critical factors on the lateral load resistance performance of metal-to-PBSP single-bolt connections. Experimental results indicated that the lateral resistance loads of the metal-to-PBSP single-botl connections were significantly affected by its shear strength parallel to bamboo strand orientation, tensile strength perpendicular to bamboo strand orientation and bolt-bearing strenth in PBSPs. Lower tensile strength perpendicular to bamboo strand orientation of PBSPs can limit its usage as connection members resisting lateral loads. The proposed mechanical model was verified experimentally as a valid means for deriving estimation equations of lateral resistance loads of unconstrained metal-to-PBSP single-bolt connections evaluated in this study.
