Optimization of steel plate girders in bending: Using FEM-analyses on S690 and S890 steel plate girders

A parametric study, using the FEM-software package ABAQUS, validated on experimental results found by Abspoel, was conducted on S690 steel plate girders to address if the results of the previous researches was valid. Using a slightly different analytical model the results show the maximum web slenderness of this steel grade in both 6000 mm2 and...

Semi-analytical method of buckling strength prediction for plates stiffened with T-shaped stiffeners having slender (class 4) webs

A master thesis about stiffening plates with very slender stiffeners is presented. The master thesis represents a completion of my master studies and is written in order to qualify for the degree of M.Sc., Master of Science in Structural Engineering at Delft University of Technology. Current work is done in close collaboration with Iv-Consult,...

Defining parameters for buckling checks of plated structures in finite element sofware packages.

Plated structures are widely used in many engineering structures. Most designs are poor in resisting compressive forces. Usually, the buckling phenomena observed in compressed conditions take place rather suddenly and may lead to catastrophic structural failure. Therefore it is important to know the buckling capacities of the plates and...

Interaction between plate and column buckling

The interaction between plate buckling and column buckling has been studied. Also a design recommendation is made for engineers working with class 4 cross-sections.

Plate buckling in design codes: The difference between NEN 6771 and NEN-EN 1993-1-5

Slender steel plates loaded in compression will buckle out of plane before their cross-sectional capacity is reached. Precisely determining the failure load in an analytical way is an impossible exercise. Therefore many researchers have put effort into finding a simple design method, which would still predict the plate buckling load with the...
