| Popis: | U radu je analiziran utjecaj radijusa horizontalne krivine, kuta kosine stupova i oblika stupova na seizmički odziv mosta. Ukupno je analizirano 18 mostova okvirnog sustava. Za potresne zapise koji po magnitudi, udaljenosti od rasjeda i uvjetima temeljnog tla odgovaraju određenoj lokaciji, provedeno je više od 2700 nelinearnih dinamičkih analiza. U analizi odziva uočeno je da manji radijus krivine znači i veću oštetljivost sustava. The influence of horizontal curvature radius, bridge bents skew angle, and type of column bents, on the seismic response of bridges is studied in the paper. A total of eighteen frame-system bridges were analysed. More than 2700 nonlinear dynamic analyses were conducted for earthquake records matching a particular location by the magnitude, distance from fault, and foundation soil conditions. The response analysis shows that the system’s vulnerability increases with a decrease in curvature radius. |
