COMPARATIVE STUDY OF STRUCTURAL DESIGN (BY STAADPRO) OF TWO STOREYED RESIDENTIAL BUILDING IN EARTHQUAKE ZONES II AND V

1.        Reinforcement required for the building in zone II is always less that the reinforcement requirement for the building in zone V.  2.        Minimum ratio of reinforcements required for columns from footing to ground level is 4.94 and   maximum ratio is 11.59. 3.        Minimum ratio of reinforcements required for Columns from ground level to first floor level is 5.75  and maximum ratio is 14.18.  4.        Minimum ratio of reinforcements required for  Columns from first floor level to second floor level is  3.07 and maximum ratio is 11.99.       5. Minimum ratio of reinforcements required for columns    from second floor level to mumty roof level is 3.47  and maximum ratio is 10.58.         6. Ratio of zone factor is 3.60. But ratios of reinforcements are not in the same pattern. Hence any  rational conclusion could not be made.
