I have a 26 story building in seismic zone 3. The main lateral system consist of 46'x46' interior concrete core with additional perimeter frame for 25% EQ loads. When I am modeling my shear walls with 4 corner supports, I am getting huge lateral forces even in DL or LL cases. Overall lateral force is zero as the forces are equal and opposite in direction at each corner. But when u have load combinations, this forces add up and give me huge base reactions.
I was wondering if any of u know any better technique to get rid of this reactions due to DL or LL? (note: there are no errors in the model)
