The article presents a comparative numerical analysis of various ways to strengthen historical brick arches. Five ways of strengthening brick arches with steel tie-rods have been proposed. Two of these involve the use of braces wrapped around pillars supporting the arch connected with a tie-rod; another two ways involve the use of the tie-rods with welded metal sheets of different sizes; the last way involves the use of the tie-rod glued with use of epoxy adhesive. The collected data were compared with the reference model of the arch left without any interference. The obtained results allow to evaluate the used methods' effectiveness by comparing displacements in the vertical and horizontal direction, and stresses. The article indicates the direction of proper planning and design of the arch strengthening in brick structures, which often occur in historical buildings.
