Zacharopoulos 1 Department of Civil Engineering, Democritus University of Thrace, Xanthi, Greece 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. http://pubs.sciepub.com/ajme/5/4/6/ajme-5-4-6.pdf temperature propagation and growth of cracks longest stay- cable of Rion - Antirion bridge lightining strike cut down
