Repairing of masonry arches using FRP in historical structures

In this study, experimental examination of various repairing techniques applied to damaged masonry arches has made. Similar to historical masonry constructions, lime based low-strength mortar is used in arch samples which are laid with pressed brick. Totally, seven knitted masonry arch samples had kept until reach to adequate strength (28 Days). Then they attached vertically at the key block level. The first sample (reference sample) was loaded until the ultimate load, other six samples were exposed to damages at the decided load weight. Damaged samples had been subjected to loading with FRP strip and mortar applications until the load carrying capacity. Repaired masonry arch samples were modelled via using the analysis program and the results were compared with experimental outputs. Finally, it is seen that in comparison to reference sample, repairing damaged masonry arched with FRP strip provide a minimum %58 rise in bearing capacity and loading joints with epoxy mortar is an alternative to rising significantly capacity of masonry arch without leading to any visual change of the construction.
