    Critical Imperfections for Columns bracing

    Thanks 271828, I understand Lq concept (in Appendix 6 -AISC2005) that counts for column flexural rigidity. My key problem is how to determine the initial imperfection (Do) for the nodal bracing system with many brace points ? say 3 braced points. If the applied load (P) > buckling load...

    Critical Imperfections for Columns bracing

    Hi all, Initial imperfection (Do)is one of the most important steps to determine the bracing strength and stiffness requirements. In the AISC 2005, and the number of Yura and Hewig papers show that Do=0.002Lb (Lb: unbraced length. However, this is based on the “full-bracing”- Winter’s model...
