Bearing capacity of L-shaped latticed joints connected by welding of screw-fitted dowels

Three kinds of L-shaped latticed joint were designed to study the shear bearing capacity joints prepared by welding wooden dowels with self-tapping screws. The results showed that such composite in all specimens varying degrees bending and splitting on surface beech dowel after test. was moment at geometric center four dowels. force each generated from equal same direction. ultimate standard value theoretical loading (F) 4.44 kN calculated design (Fd) 2.96 kN. errors between test 3.94 11.2% 24.9%, respectively. relatively consistent value. If applied estimate joint, it conservative side.
