Analysis IASC-ASCE Benchmark Structure in ANSYS Classic

[rupika]

Hi all,
I want to model IASC-ASCE Benchmark Structure in ANSYS Classic. In this structure columns and floor beams should be modeled as Euler-Bernoulli beams and braces (L angle) should be modeled as bars with no bending stiffness. What are the appropriate elements for that? I used beam188 element for column and beam sections. But I have no idea to model braces with no bending stiffness. Please help me.....

Hi, Rupika!

Please, pay attention that BEAM188 element is a Timoshenko beam, i.e. not a Euler-Bernoulli beam (use BEAM4 or BEAM44 instead). I strongly recommend to read from Ansys help the full description of element type before using it (criteria for using such element and estimation of errors involved and also modelling of structural elements hints are listed there).

For braces you could use link8 which is suitable due to the fact that it takes only axial load (no bending).

Success!
