U EN1998-1 i EN1998-2 su propisane metode za određivanje seizmičkih uticaja koje koriste linearno-elastične modele u modalnoj analizi sa spektrima odgovora. Za regularne konstrukcije, se može primeniti i ekvivalentna statička metoda u slučaju da ne postoji značajan doprinos viših tonova na odgovor sistema. U EN1998-2 su propisane, kao alternativa linearno-elastičnim metodama analize, nelinearna statička analiza i nelinearna dinamička analiza. U ovom radu su primenjene linearne i nelinearne statičke i dinamičke analize armiranobetonskih grednih mostova sa različitim kombinacijama dužina stubova u cilju procene seizmičkih performansi.
The EN 1998-1 and EN1998-2 prescribed methods for the determination of seismic action using linear-elastic models for modal analysis with response spectrum. For regular structures, can be applied to the equivalent static method in the action that there is a significant contribution to higher modes on the response of the system. The EN1998-2 are prescribed as an alternative to linear-elastic methods of analysis, nonlinear static analysis and nonlinear dynamic analysis. This study applied linear and nonlinear static and dynamic analysis of reinforced concrete girder bridges with different combinations of length piers in order to assess the seismic performance.
