Identification, repairing, strengthening and revitalisation of existing buildings structures in seismic prone areas

摘要

To satisfy the requirements for aseismic design of high-rises in seismically active regions, it is necessary to apply a modern concept of design that, apart from strength and deformabil-ity, shall consider plastic excursions and seismic energy dissipation ability. Namely, in the process of design or during repair and strengthening of existing, usually masonry structures, care should be taken to incorporate elements that shall eliminate the unfavourable behaviour of masonry and shall enable its favourable behaviour under strong seismic effects. Most frequently, a solution is sought in combinations of masonry with other materials that are characterized by a higher ductility and tensile and shear strength. Based on the performed synthesis of results from analytical and experimental investigations of elements of masonry systems in the world and in our country, as well as the investigations carried out in IZIIS - Skopje, proposed a procedure for design and analysis of new structures as well as repair and strengthening of damaged masonry systems exposed to static and dynamic effects.
