Understanding Types of Structural Loads Ever wondered how different loads act on structures in real life? From masonry walls to sloped roofs, the way loads are distributed plays a crucial role in structural design. Uniformly Distributed Load (UDL) Spread evenly over the entire length, seen in masonry walls resting on beams. Uniformly Varying Load (UVL) Varies across the span, often experienced in sloped roofing systems. Point Load Concentrated at a single point, such as columns supporting beams.
