What is one way shear and two way shear?

One-way shear occurs in structural elements like beams when the load is applied in one direction, leading to shear forces acting along a single plane. In contrast, two-way shear occurs in elements such as slabs or flat plates, where loads are applied from multiple directions, resulting in shear forces that act on two planes. Understanding these shear types is crucial for proper structural design and ensuring stability and safety.
