From the initial design phase of offshore structures to subsequent modifications and life extension,structural engineers must keep the possibility of accidents in the back of their minds.When designing new assets,they need to consider accidental scenarios and prove the structural integrity with progressive collapse analysis software.Some results are removed in response to a notice of local law requirement.For more information,please see here.12345Next
