AB  - A case study has been performed on a prestressed bridge with simple span in order to investigate
the seismicbehavior of prestressed segmental bridges. In this study, nonlinear dynamic time history analysis
has been used in the 3-dimentional finite element model of the structure under one-component vertical
excitement and tree-component earthquake. Consequently, the degree of vulnerability of different parts of the
bridge deck has been evaluated under vertical and horizontal components of the earthquake. The decks of
prestressed segmental bridges are usually designed for vertical loading from permanent and service loads. The
design of these bridges against the loads from earthquake is mainly performed for horizontal components of
the earthquake and mostly the piers and foundation will be under effect. However, in such bridges concerning
the long spans, the vertical excitements of the earthquake might be very impressive. The main focusing is on
the vertical excitations of earthquake in the present study.
