Hi Guys,
I am curious why does ETABS report mode shape with units. Back in my uni day, I was constantly reminded by my professor that the mode shape is mathematically just an eigenvector...It does not have "any" real magnitude and only indicate the shape of the structure.
Is there any reasons...
Hi Guys,
I am sure most of us here are familiar with the stiffness modification factor stipulated in ACI 318-14.
For beams and columns, the application of stiffness modifiers can be easily incorporated into ETABS analysis by modifying the respective moment of inertia.
My question here is how...
