We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.
BEAM188 is suitable for analyzing slender to moderately stubby/thick beam structures.
Yes, it is true that BEAM188 is based on Timoshenko beam theory which includes shear-deformation effects. The element provides options for unrestrained warping and restrained warping of cross-sections.
The transverse-shear distribution calculation ignores the effects of Poisson's ratio. The Poisson's ratio affects the shear-correction factor and shear-stress distribution slightly, and this effect is ignored.
Shear-correction factors for some common sections are as follows: rectangle (5/6), solid circle (9/10), thin-walled hollow circle (1/2). These are fixed values and cannot be changed.
For the arbitrary section (ASEC), shear-correction factors can be input directly using the command SECDATA.
