Finite Element Analysis workflow

By |May 2nd, 2017|FEA: Basics, • Linear Analysis, • Meshing, • Boundary Conditions, • Post Processing, FEA Topics:, RFEM, FEMAP|

When I first started working with Finite Element Analysis (FEA) I had a huge problem in understanding what to do. I had a basic engineering knowledge but I simply did not understand what was the order of the steps. Suddenly the software had many "modules" and each was screaming at me that some data is [...]

Connection rigidity: 5 things you need to know!

By |February 13th, 2017|• Structural Steel, • Connections, Structural Design Topics:, RFEM|

Most engineers use a popular approach: connection is either a hinge or a rigid one. This is usually not the case. Just as with many other engineering problems in certain cases we simplify the reality by assuming perfect conditions (i.e. hinge). It is crucial to understand when such assumptions are incorrect, as this may lead [...]

Critical bending moment: How to calculate it with numerical analysis (in RFEM)

By |May 29th, 2016|• Structural Steel, • Stability, FEA: Intermediate, FEA Topics:, • Linear Buckling, Structural Design Topics:, RFEM|

Lateral torsion buckling (LTB) is a very dangerous phenomenon, that can easily cause the collapse of a poorly designed beam. In civil engineering codes, the critical bending moment is crucial in the proper design of bent beams susceptible to LTB, as it allows for slenderness calculation.  In “typical” cases everything is ok since code equations [...]
