چکیده
Bridge is a communication and transit route that today is considered as a special structure for its design, considering its importance and its application. One of the most important factors in its investigation is natural and abnormal factors. In this paper, it has been tried to evaluate two factors, including earthquake and fire, which are both natural and abnormal factors in concrete prestressed bridges. The characteristics of each one are investigated in these situations. Their results are used for constructive design in such bridges
.Currently, prestressed concrete (PC) bridges are often suffered from fire caused by oil tanker. However, there is very little
research information and test data in the literature on the fire resistance of PC bridge girders. This paper presents an investigation
into behavior of I bridge girder under hydrocarbon fire condition and including area and spine models, were applied to a simply-supported, curved PSC Igirder
bridge under an ensemble of 3D synthetic ground motions

The characteristics of each one are investigated in these situations. Their results are used for constructive design in such bridges
