In the Element Library, for element type beam188, it is stated "A slenderness ratio greater than 30 is recommended". What is the impact of using this element type for modelling of structural elements with slenderness ratio less than 30? What type of error would this generate in the analysis output?

 

Any help gratefully received!

Hi,

It seems the minimum slenderness ratio value 30 is given, because a beam is refered as short if the slenderness ratio is less than 30.

As the formulation for beam188 is for slender beam, a slenderness ratio greater than 30 is mentioned. However, you can use the element for slenderness ratio less than 30 as well. The results won't be much different (most probably). I suppose it won't give any error.  

Thanks,

Aurojyoti.
