Non- preloadable bolts are widely used in the European framework; the EN 1993:1-8 provides design rules for bolted connections based on simplified elastic perfectly plastic response of bolts, disregarding their ultimate deformation capacity. However additional information regarding their post elastic behavior are needed when this type of bolts is used in seismic areas; therefore in this work, the monotonic behavior of no pre-loadable grade 8.8 SB (Structural Bolting) assemblies was investigate by a set of 6 experimental tests performed at the University of Naples Federico II. Three bolts diameter where investigated: dl6, d20 and d24. The results are depicted in terms of both force-displacements curves and failure mode in order to monitor not only the elastic segment but to investigate the post elastic behavior and their ductility.

Abstract
Non- preloadable bolts are widely used in the European framework; the EN 1993:1-8 provides design rules for bolted connections based on simplified elastic perfectly plastic response of bolts, disregarding their ultimate deformation capacity. However additional information regarding their post elastic behavior are needed when this type of bolts is used in seismic areas; therefore in this work, the monotonic behavior of no pre-loadable grade 8.8 SB (Structural Bolting) assemblies was investigate by a set of 6 experimental tests performed at the University of Naples Federico II. Three bolts diameter where investigated: dl6, d20 and d24. The results are depicted in terms of both force-displacements curves and failure mode in order to monitor not only the elastic segment but to investigate the post elastic behavior and their ductility.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
