old bethlehem steel joists
i saw an earlier post regarding the designations for bethlehem steel joists ("1951 longspan joist puzzle" from 2006). it appeared that "jcali" had load table information on these members. does anyone have this information? the 1950 drawings that i have specifically refer to "bethlehem joists" and i need to confirm their capacity. i would appreciate any help. thanks.
