A building 300 m high must have 75 to 100 floors suggesting as many lumped masses as the number of floors and number of springs = number of floors. Webbuildings. Usually, natural periods (T) of 1 to 20 storey normal reinforced concrete and steel buildings are in the range of 0.05 - 2.00s. Resonance will occur in a building, only if frequency at which ground shakes is steady at or near any of the natural frequencies of building and applied over an extended period of time.
