SDOF analysis of overpass columns influenced by blast load

Važnost mostova za svaku državu dovodi ih u položaj terorističkih meta djelovanjem eksploziva. Zato je važno prilikom projektiranja uzimanje u obzir i izvanredno djelovanje eksplozije. Iako su ispitivanja vrlo skupa i složena uporabom računalnih programa može se simulirati djelovanje eksplozije na mostove i odgovor konstrukcije na nju. U obzir su uzete tri količine eksploziva koje djeluju ispod nadvožnjaka i dobiveni su rezultati pomaka, deformacije, sile u opruzi, sile prigušenja.The significance of bridges for every country places them in a vulnerable position as potential terrorist targets, given the threat of explosive actions. This underscores the crucial necessity of considering the profound impact of explosions during the design phase. While conducting physical tests for this purpose proves to be both costly and intricate, the utilization of computer programs enables the simulation of explosion effects on bridges and their structural responses. In this study, three different explosive quantities were considered in the scenario of an explosion occurring beneath the overpass. The subsequent outcomes encompassed measurements of displacement, deformation, spring force, and damping force
