Consideration of the net cross-section for tensile stress according to EN 1993-1-1
When connecting tension -loaded components with bolted connections, the cross -section weakening due to the bolt holes must be considered in the ultimate limit state design. The following article describes how the design of the tension resistance according to DIN EN 1993-1-1 can be performed with the net cross-section area of the tension member in the RF-/STEEL EC3 add-on module.
SHAPE-THIN | Cold-Formed Sections
SHAPE-THIN determines the effective cross-sections according to EN 1993-1-3 and EN 1993-1-5 for cold-formed sections. You can optionally check the geometric conditions for the applicability of the standard specified in EN 1993‑1‑3, Section 5.2.
The effects of local plate buckling are considered according to the method of reduced widths and the possible buckling of stiffeners (instability) is considered for stiffened sections according to EN 1993-1-3, Section 5.5.
As an option, you can perform an iterative calculation to optimize the effective cross-section.
You can display the effective cross-sections graphically.
Read more about designing cold-formed sections with SHAPE-THIN and RF-/STEEL Cold-Formed Sections in this technical article: Design of a Thin-Walled, Cold-Formed C-Section According to EN 1993-1-3.
- I would like to calculate and design "temporary structures." What do I need for this?
- How can I additionally model welds for the connection of two surfaces with a contact solid?
- I would like to use surface releases to model a bolt connection, which can only absorb compressive stresses from the support. Unfortunately, I cannot do this because my model is always unstable. Is there a model as a template?
- Are the models and presentations from Info Day 2017 freely available, and can you send them to me?
- How can I model and design general bolted connections with the surface and solid elements in RFEM?
- Are the models and presentations from Info Day 2015 freely available, and can you send them to me?
- How can I display the contact stresses on a contact solid?
- The calculation of my model results in unrealistically high stresses at many locations. What is the reason?
- How can I model a support of a member on a bracket with screws?
- Are the models and presentations from Info Day 2019 freely available, and can you send them to me?
