WebMay 23, 2011 · Using Sum of Reactions in RISA-3D. RISA-3D will now check your model for errors by summing the reactions in your model and comparing them to the applied loads. This occurs for the global X, Y, and Z directions. If RISA identifies that the reactions do not equal the applied loads then the software will show a warning message to the... 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.
