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...
g'day!
i have a 3D model of a multistory bldg in etabs with a dual sytem, a shearwall and moment resisting frames.
how would you check your base shear on moment resisting frames that these frames independently resist 25% of the base shear and 75% on the shear wall according to the UBC code?Can...
