Assigning non-uniform loads in ETABS can be a bit confusing, especially for beginners. ETABS follows its coordinate system for assigning non uniform loads. To clarify this, I conducted hand calculations and compared them with ETABS analysis results to better understand how to assign non-uniform loads accurately.
I applied non-uniform loads in two ways:
1. When the origin coordinate is at the bottom of the wall.
2. When the origin coordinate is at the top of the wall.
By reviewing this detailed comparison, I believe it will help others the proper way to assign non-uniform loads. Take a careful look at the post, and I’m confident it will clear up any confusion.
