Buckling behavior of built-up thin-walled I-beams with trapezoidal flanged cores

This database supports the study on the stability of built-up thin-walled I-beams with trapezoidal flanged cores, demonstrating their enhanced resistance to buckling compared to traditional beams of equivalent mass. It includes experimental data from three-point bending tests, numerical results from finite element analysis, and material specifications of the beams. Key entries document critical force values, deformation patterns, material properties, and bonding methods, providing a comprehensive foundation for analyzing buckling behavior in trapezoidal-flanged structures.This database includes:experimental data,numerical model of the beam,charts and graphical results,images of the test stand.Please consult the Readme.txt file for additional information.
