Abstract

The phases that must be completed so that a building damaged in earthquake that struck Zagreb on 22 March 2020 can be renovated and strengthened to the required level of seismic resistance are presented in the paper. All phases are therefore presented, starting from the rapid and then detailed inspection, and continuing with preparation of the structural condition assessment report, preparation of renovation design and, finally, ending with realisation of work with expert supervision. A special attention is paid to structural analysis that is conducted using a nonlinear static method based on displacements, the so called pushover analysis, which is considered to be one of the most appropriate methods for seismic analysis of existing masonry structures. All procedures conducted in the scope of this renovation were realised in accordance with legislation that entered into force after the earthquake.
