The scordelis-lo roof

Webb1 okt. 2005 · The Scordelis–Lo roof is subjected to gravity loading. The ends are supported by fixed diaphragms and the side edges are free (see Fig. 37). The vertical displacement of the midpoint of the side edge is the quantity used to assess convergence. These meshes have 2, 8, and 32 surface elements per side, respectively. WebbThis test, also known as the Scordelis-Lo roof, lets you check analysis results for a cylindrical roof under its own weight, in the context of a static case. You will use 2D meshes.
