The story inertia forces and story shear forces from the response spectrum analysis could be obtained in format of a table. For response spectrum case is obtained from combination of each mode using modal combination method. Shear Force represents the sum of shear forces of all the upper stories as well as the corresponding story, and Story Force represents the shear force acting on the corresponding story. A: For response spectrum, the Story force obtained for each mode(from Eigenvalue Analysis) is combined using suitable modal combination method.
