WebJun 22, 2024 · Notional loads are rarely important for real structures under typical code loads. You have to have cases where the axial load during gravity loads is a lot higher than for the lateral cases. Or, when you have very little lateral load. A good example might be internal mezzanines in non-seismic areas. WebLoads: DL = 0.2 klf (includes weight of girder) ...

WebJun 18, 2014 · It will work well for all gravity only load combinations because it truly adds lateral stability. Make the spring too stiff, though, and it will also affect your lateral load combinations. Make it too soft and you will still be prone to P-Delta type instabilities in your frame. Any of these solutions are okay. WebAdd Notional Loads to Wind I£ad Combinations?
