The ability to input the importance category of the building would be helpful. Currently the importance category is assumed "Normal" and a SLS importance factor of Is=0.9 is applied for snow load deflections. However, if the building is "High Importance" or "Post Disaster", the snow load for deflections should first have the ULS importance factor removed (Is=1.15 or 1.25), then have the SLS factor applied (Is=0.9). With the current system, Forte is overestimating snow load deflections for High Importance and Post-Disaster buildings.
Hi, can you include changes to importance category?
thanks
