Abstract

In this paper we considered if temperature effects propagation and growth of cracks in a stay- cable of cable- bridge due to lightining strike. We dealed with the longest stay- cable of M1 pylon of Rio –Antirio bridge. We showed that after an hour the last will be cut down. Our result coincides with reality, since on 2005 a lightining stroke cut down the longest stay cable at M1 pylon of Rion- Antirion bridge. We concluded that temperature plays a great role to propagation and growth of cracks.
