The boundary condition for the Floor 12 and 13 assembly was obtained by analyzing the Floor 3 to 12 combination. The computer model included spring stiffnesses to simulate each connection type. The spring stiffness at the four far corners of Floor 12 was then checked by imposing unit forces in both horizontal directions x and y at each corner, then calculating the
