Article history: In this paper, pushover analysis of fixed jacket offshore platforms with the application of “Fiber Elements”
Received 21 January 2007 which are capable of modeling post-buckling behavior of braces has been conducted and case study on
Accepted 10 March 2008 two functional jacket offshore platforms in the Persian Gulf region has been performed. Two-dimensional
models of the mentioned platforms are simulated using “DRAIN-3DX” software and the wave force is
