The study presents innovative anti-seismic protection systems using PolyUrethane Flexible Joints (PUFJ) at the frame-infill interface and bonding of glass fiber meshes to the weak masonry substrate to form Fiber Reinforced PU (FRPU) as an emergency repair intervention. Due to the possibility of using the systems in existing and newly built structures in areas of increased risk of seismic excitations, the authors made an attempt to define the life cycle scenarios of these systems in terms of the possibility of extending the service life of these structures. The definition of the construction life cycle scenarios and the estimation of the corresponding investment costs and costs related to the operation and decommissioning of a given system were based on the approach presented in the ISO 15686 standard package "Buildings and constructed assets", part 2 – Service life prediction procedures and part 5 – Life cycle costing. The simulations covered a total of five variants of the systems application: (i) prefabricated PUFJ at 4 interfaces (in newly constructed buildings), (ii) injected PUFJ at 3 interfaces (improvement of existing buildings) and application of FRPU as a quick emergency or strengthening system (for buildings damaged by earthquakes) in variants (iii) at infill diagonals, (iv) at infill edges, and (v) as combination of the systems presented above (according to requirements). The cost analysis also took into account the potential impact of changes in the value of money over time and an increase in the production costs of building materials.
