Dear all,

Are there any easy approximate methods for time saving and for getting reliable values?
i have been using Moment distribution method,But now just changed to the IS 456 method (CL 22.5). But the problem is, the moments i get through this method are very distinct than which i get from ETABS or STAAD.

Please kindly help.


Thanks in Advance.

Renju Mathew.

Dear Er Matthew,

The coefficients in table 12 of IS: 456 include an allowance for redistribution of moments. Hence, these values won't match an elastic analysis.

If you want to check your computer output, a partial substitute frame analysed by the moment distribution method is your best bet.

"i think, we have to develop a new approximate method for a quick check"
