This Part of BS 6779 specifies requirements for the
design and construction of combined concrete and
metal parapets to provide specified levels of
containment for vehicles on highways. Normal
containment parapets have concrete panel heights
of 0.4 m to 0.8 m with one, two or three effective
longitudinal metal members. High containment
parapets have a panel height of 0.9 m and a single
metal, effective, longitudinal member. The metal
members are carried on metal posts attached to the
concrete panels which may be in situ or precast,
with or without shear transfer. Prestressed concrete
and parapets designed to act compositely with the
main structure are not covered in this Part of
BS 6779.
