Possible types of failures in a steel structure

The possible types of failures in steel structures.Steel is a ductile material and to build a structure using steel is like setting up a huge Jigsaw puzzle.You have 1000 different members and you need to connect them and tada..!! Your structure is up.But it is not as simple as it is visible.Steel being a very strong material leads to People also askWhat is fatigue of steel?What is fatigue of steel?2.Fatigue of Steel Structures Fatigue failure may occur when a cyclic tensile stress is applied to a component or structure.Failure is progressive,each stress cycle causing incremental growth of the fatigue crack.Fatigue crack surfaces are often characterised by regular steps,each step being due to the crack growth during one cycle.2.Fatigue of Steel StructuresManufacturer Ernst SohnFormat KindleDNVGL-RP-C203 Fatigue design of offshore steel structures DNVGL-RP-C203 Fatigue design of offshore steel structures Recommended practice.This recommended practice (RP) presents recommendations in relation to fatigue analyses based on fatigue tests (S-N data) and fracture mechanics.Conditions for the validity of the recommended practice are given in Section 1.2 in the RP.
