A new design proposal for composite beams with powder actuated shear connectors

This paper introduces a proposal for the SP 266.1325800 code update, which is applied as national building composite structure design in Russian and some CIS countries. The based on deep codes analyze comparison previous authors’ publications. research dedicated to nailed shear connectors’ behavior beams with profiled sheeting. provides less conservative approach ductile connectors takes into account additional conditions, such decking geometry structure’s performance under fire. proposed methodology defines main geometric characteristics of cross-section before determining connector type. If are chosen, it recommended use partial methods connection definition due economic benefits proposal. verified powder-actuated should be double-checked other working examples types. results show that designed according new 13% utilized smaller quantity (22% less) same load. It from costs labor time.
