cracked sections for frame analysis
cracked sections for frame analysis
(OP)
when analysing a reinforced concrete moment frame do i have to use the effective moment of inertia specified in ACI such as col:Ie=0.7Ig;beam:Ie=0.35 Ig and so on...when i used this and satisfy the drift requirement i always get results of bigger sections than analysing it with out modifying the moment of Inertia, structural system is SMRF.can somone help me with this one?thanks

yes i am using the Ie as provided for moment magnifications.
thanks for the reply guys.

It specifically states that this is for the calculation of Pu, M1, M2, and delta(o).
