Abstract (english)

Post-earthquake assessment can be defined as a procedure to define the given structure’s safety and usability after an earthquake. The seismic behaviour of buildings depends on numerous parameters such as the construction, building material, the geometry of the structure, stiffness properties and non-linear aspects, conceptual design, etc. The main importance of seismic design is to protect property and life in buildings and infrastructure in case of earthquake events. However, an appropriate seismic design approach must necessarily develop on knowledge and feedback from existing structures. Past events showed that seismic loads usually cause significant damage in masonry buildings due to their large mass and stiffness compared to other constructional typologies and materials.The last decade has seen a growth in the technological development of various tools that can greatly help predict structural safety and seismic behavior of existing structures. The applicability of the thermal camera for building diagnostics and detection of energy-related building defects has been investigated by numerous authors. Nowadays, technology and sensor minimization enable the development of the multi-sensor costume-made UAV (Unmanned Aerial Vehicle) for multi-sensor aerial mapping and post-earthquake damage assessment. When doing on-site assessment from a street-level, an engineer cannot see what happened to a building on higher floors or roof of a structure. The main problems (especially for moderate-intensity earthquakes) are chimneys, damaged roof structures, damaged gable walls, etc. With a UAV device, all of the mentioned information can be easily assessed.
