The design code in Italy is :
CNR-UNI-10011 "Steel Structures - Instruction for design, construction,
testing and maintenance".
It is in Italian language only.
Than, to define loads due to the wind od live loads on structures, there is
a "Decreto Ministeriale - 16 gennaio 1996"
"Norme tecniche relative ai Criteri generali per la verifica di sicurezza
delle 
costruzioni e dei carichi e sovraccarichi"

Usually, who work with a not Italian client, refers to the codes of the
client or
performs all structural check  according to Italian codes and to Client codes.
If should be of some help, data for class 8.8 bolts are ( from CNR-UNI
10011 ):
Tensile strength  ft = 800  N/mm2
Yield strength 	 fy = 640  N/mm2
CNR-UNI 10011 - Allowable stresses
Tension stress    sb = 273 N/mm2
Shear stress      st = 264 N/mm2

For structural steel, we have :
Fe 360 		fy = 235 N/mm2		All.stress  160 N/mm2
Fe 430 		fy = 275 N/mm2		All.stress  190 N/mm2
