Bolted Connection Tests of Thin G550 and G300 Sheet Steels

摘要

Cold formed structural members are fabricated from sheet steels which must meetthe material requirements prescribed in applicable national design standards. This report details the findings of bolted connection tests using G550 and G300 sheet steels which range in base metal thickness from 0.42 to 0.60mm. Test specimens were milled from the longitudinal, transverse and diagonal directions of the sheet to determine the degree of anisotropy and its effect on connection capacity and failure type. All specimens failed in one of three distinct modes; end pull-out, bearing or net section fracture.
