Question
How many mode shapes do I need to consider in the dynamic analysis?
Question
I am designing a tapered beam and I get the message "Non-designable: ER051 Moment about z-axis on asymmetric cross-section, taper, or set of members". Why?

Calculation of Cable
When calculating a cable using the STEEL EC3 add‑on module, there is the error message "Incorrect characteristic stresses for material No. 1! Please correct this in Table 1.2."
Question
I would like to perform a stability analysis of the upper flange in a long truss. What is the best way to proceed?
Question
What is the formula used to calculate the ASCE 7 wind velocity profile?
Question
I would like to connect a column rigidly to a girder flange. However, in the RF‑/JOINTS Steel - Rigid add-on module, beams are always connected to a column flange. How can I create a continuous beam?
