You can learn how to complete the design for waist slab, flat slab, risers and treads which are vital parts of a staircase. The upper step is on the same level with the floor plane; the desired relationship between the number of steps and their height. If instead stair angles range from 20° to 30° and from 40° to 45°, the level of comfort will be significantly reduced. In this post, we are going to model a simple staircase using finite element plates, and compare the answer with manual calculations in which we assume the staircase to be a simply supported beam.
