I'm trying to model a two-way concrete slab and beam system in etabs. I have the slab elements( h=150 mm) and rectangular beams (400 mm depth x 300 mm width) , but when I view in 3-d, it appears that everything is being modeled from the centerline of the elements. How can I change my model so...
hi everyone
in Staad pro there is feature (I.M.R)individual model response
please anyone know this feature how to do it in ETABS
this feature make response spectrum effective by giving each results its own sign (negative or positive)
Thank you
Hi every one
In a response spectrum analysis, the base shear does not match the summation of shears I get at the base of the columns. Which one should I use as base shear ? how to solve this problem?
hi everyone
i have 10 story building when calculate base shear from reaction and story force they have same value but when use accidental eccentricity(5%) the base shear calculated by summation of the reactions is larger than when calculated by story shear so i cant understand why this...
hi everyone
Q1) why etabs dont consider the change in accidental eccentricity so all base shear results are the same whatever the value of accidental eccentricity ?
Q2) i have rectangular building (40x20)m, why the natural frequency in the orthogonal directions dont have a big different ?
Thank...
