Warning in STAAD PRO output file "Length to Depth Ratio is Less than 2.5"

Dear Frnds...

I am facing a warning in Staad pro output file during Concrete design...."Lenght to depth ratio is less than 2.5"... for short length beams.....somebody help me how to remove this warning...

will my design be correct with this warning in output file  or not....??

Plzzzz...reply

Thanks & regards

  • Can you please copy and paste your input file into a forum post so we can take a closer look?

     Thanks,

  • Deep beam is not designed in STAAD. Thus whenever a beam is sub-divided into many sub-beams then L/d ratio is decreased since in this case length (L) is the length of the sub-beam and not the whole length of the beam extending between two columns. Thus a warning message is thrown to let the users know about the fact that L/d ratio is less than 2.5 and it is becoming a deep beam. In this case ordinary shear check will be performed . This is has no relation with deflection check.



  • I have the same warning... Pls help me sir.

  • Deep beam is not designed in STAAD. Thus whenever a beam is sub-divided into many sub-beams or you model a beam of small length , then L/d ratio is decreased since in this case length (L) is the length of the sub-beam and not the whole length of the beam extending between two columns. Thus a warning message is thrown to let the users know about the fact. In this case ordinary shear check will be performed.

    I would suggest that you use ENSH 1 parameter for those beams where the program reports L/d is less than 2.5 to ignore enhanced shear strength
