Preloaded Bolts for Steel Joints
First Steps with RFEM
In the Steel Joints add-on, you can consider the preloaded bolts in the calculation of all components.
You can easily activate the preload using the check box in the bolt parameters. This has an impact on the stress-strain analysis as well as the stiffness analysis.

Plate girder is an economical choice for long spans construction. I-section steel plate girder typically has a deep web to maximize its shear capacity and flange separation, yet thin web to minimize the self-weight. Due to its large height-to-thickness (h/tw) ratio, transverse stiffeners may be required to stiffen the slender web.
