Defining the appropriate effective length is crucial to obtain the correct member design capacity. For X-bracing that is connected at the center, the engineers often wonder if the full end-to-end length of the member shall be used or using half of the length to where the members are connected is sufficient.
This article outlines the recommendations given by the AISC and provides an example on how to specify the effective length of the X-braces in RFEM.
For the joint components, it is possible to check whether the stability failure is relevant (requires the Structure Stability add-on for RFEM 6 / RSTAB 9).
In this case, the critical load factor for all analyzed load combinations and the selected number of mode shapes is calculated for the connection model. The smallest critical load factor is compared with the limit value 15 from the standard EN 1993‑1‑1, Clause 5. Furthermore, a user-defined adjustment of the limit value is possible. Moreover, the corresponding mode shapes are displayed graphically as the result of the stability analysis.
For the stability analysis, an adapted surface model is used to specifically recognize the local buckling shapes. The model of the stability analysis, including the results, can also be saved and used as a separate model file.
