In the world of construction engineering, the word "imperfections" has a specific meaning. In general, it describes the incompleteness of a structure or the deviation of a structural component from an ideal shape caused by the production.
This article draws a parallel between generating an FE mesh for separate objects using the “Independent FE mesh preferred” option, and generating the mesh without using said option.
In this article, you will learn how to model a simple end plate connection in RFEM 6.
Utilizing the Steel Design Add-on, steel design is possible according to the AISC 360-22 standard. The following article will compare the result output when calculating lateral torsional buckling according to Chapter F vs. an Eigenvalue Analysis.
In the ultimate configuration of the steel joint design, you have the option to modify the limit plastic strain for welds.
The "Base Plate" component allows you to design base plate connections with cast-in anchors. In this case, plates, welds, anchorages, and steel-concrete interaction are analyzed.
In the "Edit Section" dialog box, you can display the buckling shapes of the Finite Strip Method (FSM) as a 3D graphic.
- Design of five types of seismic force-resisting systems (SFRS) includes Special Moment Frame (SMF), Intermediate Moment Frame (IMF), Ordinary Moment Frame (OMF), Ordinary Concentrically Braced Frame (OCBF), and Special Concentrically Braced Frame (SCBF)
- Ductility check of the width-to thickness ratios for webs and flanges
- Calculation of the required strength and stiffness for stability bracing of beams
- Calculation of the maximum spacing for stability bracing of beams
- Calculation of the required strength at hinge locations for stability bracing of beams
- Calculation of the column required strength with the option to neglect all bending moments, shear, and torsion for overstrength limit state
- Design check of column and brace slenderness ratios
Can I add dimensions in the Steel Joints add-on?
How can I design single-angle compression member according to AISC Section E5?
How do the stiffeners on the outer flange edges of a rigid frame joint beam affect the maximum resistant moment as well as the rotational stiffness and the accompanying displacements on a frame structure?
What is the component-based finite element method (CBFEM)?
Is it possible to perform stability analysis according to EN 1993‑1‑1 in RSECTION 1?
Why is it not possible to select the plate I want to cut/edit in the Plate Editor/Plate Cut?
