Effective Lengths for Steel Stability Design
How do I define effective lengths when designing steel members in RFEM 6?
Unsymmetrical Cross-Section (UPE)
I am having trouble with the design of a steel structure. For a singly symmetric cross-section (UPE), the program cannot perform the stability analysis. It reports that the Equivalent Member Method 6.3.3 is not applicable for an unsymmetrical cross-section. Is it possible to design such cross-sections in the program?
Adapted Method (Enable Double Bending)
I cannot analyze a UPN cross-section subjected to double bending in the program. Is it possible to do this in the program?
Member Design Supports for Deflection Checks
How do I define a member as a cantilever and not as supported at both ends for serviceability or deflection design?
Stiffness Modulus Method
Is it possible to perform an analysis according to the stiffness modulus method in RFEM or RSTAB?
AISC 360-16 Shear Plane in Thread Option
Can I exclude bolt threads from the shear planes according to AISC 360-16 in the Steel Joints Add-on?
Design of Member Sets
I have activated Steel Design in my model and defined design types for the members. Why can I not design the superordinate member set?
Splice Connection
How do I create a splice connection in the Steel Joints add-on?
Overstrength Factors
How do I include the overstrength factor(s) Ωo in the ASCE 7 load combinations?
Redundancy Factors
How do I include the redundancy factor(s) ρ in the ASCE 7 load combinations?
Exclude Lateral Torsional Buckling Check
My beam has a continuous lateral support and therefore lateral torsional buckling (LTB) is not a concern. How do I define the effective length?
Uneven Terrain
The terrain surface of my soil to be analyzed is uneven. How can I edit the geometry of my soil massif for the modeling?
AISI Table B4.1-1 Applicability Limits
