CODAL PROVISION
Drift (Full structure)
Max Drift = Etabs drift *0.7*R Limitation
<0.02 in case T >0.7
<0.025in case T<0.7
Also should be checked for per floors
Story Drift = Etabs drift *0.7*R* h(floor height) Limitation
<0.02hin case T>0.7
<0.025h in case T<0.7
Wind Limitation
Total Height /500 = maximum allowed displacement Response spectrum
Scale factor
Base shear of EQx/ Base shear of Spec x =
scale factor of spec x and 0.3of scale factor for Spec y
Base shear of EQy/ Base shear of Spec y =
scale factor of spec y and 0.3of scale factor for Spec x
