Sažetak
Earthquake loading might represent the worst loading condition the structure will experience in its design life. If not accounted for it properly, the loading might be devastating for the structure and people using it, as recently witnessed during the devastating earthquakes in north-western Croatia. However, overestimating the loading might lead to very redundant structures, an unnecessary waste of resources, with negative implications to sustainability. This work presents results obtained by a numerical procedure (based on finite element method with 3D beam Euler-Bernoulli and Timoshenko elements, Rayleigh damping theory and Newmark's method of numerical integration) as well as an experimental program on a simply supported beam model (conducted by means of two biaxial seismic platforms and optical measuring system).
