ABSTRACT
For the structural engineer the major difference between low and tall buildings is the influence of the horizontal loads due to wind and earthquake on the design of the structure. Lateral deflection of a tall concrete building is generally limited to H/1000 to H/200 of the total height H of the building. In the case of tall buildings, in addition to limiting this so called lateral drift, attention has to be focussed on the comfort of the occupants because vibratory motion could induce mild discomfort to acute nausea.
