Shear deformations in slender beams are generally not significant compared to flexural deformations. But shear deformation are important in deep beams and short walls, and flexure-shear interaction may be important in the material nonlinear range of response, regardless of aspect ratio. Enough of the perfunctory, non-committal language--you can find that in the latest issue of … Continue reading Elastic Shear Beams in OpenSees

Trapezoidal Beam Loads
OpenSees will never win any awards for documentation. Although many features, e.g., Concrete23, are not documented because no one uses them, a few useful items lack documentation. For instance, did you know that you can apply trapezoidal member loads to beam elements? You can do so with additional arguments to the eleLoad command with the … Continue reading Trapezoidal Beam Loads
How to Bend Beams
How to Boil Water was one of the first cooking shows on the Food Network. Emeril Lagasse was the original host and the show was geared toward people with little to no cooking experience. Everyone starts as a beginner. PD with OpenSees is no exception. But when I'm asked where's the best place to start … Continue reading How to Bend Beams
Most Solvers Can Be Marplots
Have you ever tried to replicate the familiar beam stiffness coefficients $latex 12EI/L^3$, $latex 6EI/L^2$, $latex 4EI/L$, and $latex 2EI/L$ (there's a poem about them here) by imposing unit displacements and rotations at fixed supports? It should be one of the first sanity checks you make when using or developing new structural analysis software. You … Continue reading Most Solvers Can Be Marplots
