Abstract

Abstract: The dowel-bearing property is very important in compression yield strength calculation of bolted connections and is a critical component of wood or bamboo connection design. In this paper, the dowel-bearing strength was studied based on dimension, bolt diameter as test parameters. The application of NDS/LRFD and Eurocode 5 in dowel-bearing strength prediction was assessed. Besides, the damage modes in two loading directions were analyzed. It showed no dimension effect on dowel-bearing strength which ranged between 104.40 MPa and 169.77 MPa in either direction, if the dimension reaches the minimum requirements. The dowel-bearing strength test values showed a decreasing trend with the bolt diameter increasing. NDS/LRF and Eurocode 5 all under predicted the dowel-bearing strength of recombinant bamboo. The damage modes of the two loading direction samples were obviously different.

Key words: recombinant bamboo, dowel-bearing strength, dimension, bolt diameter, damage mode
