Bonding and anchoring of a CFRP reinforced render for the external strengthening of old masonry buildings (original) (raw)
Abstract
h i g h l i g h t s An innovative strengthening solution for loadbearing masonry wall buildings. The strengthening efficiently is dependent on bonding and anchorage behaviour. The experimental campaign allowed the validation of an end anchorage detail. The same campaign also served to prove that continuous bonding is ensured.
