Frame Stiffness Calculation a) Determine the stiffness, K, of the frame. Natural Period Calculation b) Assuming a lumped weight of 150 kips at the beam, calculate the natural period \( (\mathrm{T}) \) of the frame. c) If the natural period of lateral vibration is revised to 0.25 seconds, determine the new lumped weight applied to the beam that corresponds to this updated period.
