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. http://conference.ioe.edu.np/ioegc2024/papers/IOEGC-2024-01.pdf

Webb18 apr. 2016 · The mode shapes for a Scordelis–Lo roof will be either bending, circumferential, longitudinal, radial or torsional (Markus 1988). The first six modes are depicted for the largest thickness to length ratio in Fig. 5 , it is observed that the modes vary between longitudinal bending and circumferential bending, and no membrane … WebbThe Scordelis-Lo roof constitutes a basic benchmark problem for testing shell finite elements. The dead load of the shell amounts P g = 3 kN/m 2 , equal to the roof's self …
WebbThe Scordelis-Lo Roof is a classical benchmark problem for shell elements. Analytical and experimental investigations were initially performed by Scordelis and Lo. OS-V: 0740 Curved Strip Hook Raasch challenge is a curved strip hook problem with a tip in-plane shear load, posed in 1990 by Ingo Raasch of BMW in Germany. http://www.luxinzheng.net/download/OpenSEES/Explicit_DKGT_OpenSEES.htm
WebbScordelis-Lo Roof and the Clamped Hyperboloid. In our second study, we shortly review the MITC3 shell element. This element is known to lock in plate bending cases for a specific mesh pattern. Finally, we formulate a new MITC triangular, four node element and investigate its plate bending behavior in detail. WebbUnlike in typical PINN applications, the corresponding strong or weak form must therefore be solved in a non-Euclidean domain. We investigate the performance of the proposed PINN in three distinct scenarios, including the well-known Scordelis–Lo roof setting widely used to test FEM shell elements against locking.
