DISCUSSION OF RESULTS

6.1. As per IS 456-2000 CL : 20.5 page no 33 maximum top deflection of building due to wind
should not exceed H/500, where H is total height of building in mm, Means in our case 93240/500 is
equal to 186.48mm. For earth quake As per IS 1893-1-2002CL :7.11.1 page no 27, The story drift in
any story due to minimum specified design lateral force, with partial load factor of 1.0 shall not
exceed 0.004 times story height. For deflection 0.4 percentage of height of story it means H/250,
where H is height of story. In our case 3048/250 is equal to 12.192mm. Because of book of “Analysis
and Design of tall building “by Bryan Stafford Smith and Alex Coull, maximum top deflection of
100m height or 33 story building is 100 mm to 500 mm (6 inch to 20 inch), or, alternatively width of
