The in-plane peak acceleration amplification factors ([a.sub.max]/[A.sub.max], where [A.sub.max] is the peak acceleration of the input motion at base beam and [a.sub.max] is the peak acceleration of the response motion at infill walls or the slab) along the structural height
are shown in Figure 12.
For the increase in structural height
with reduction in column sizes which leads uncomfort to human due to deflection of top stories will be more as compared with a regular size column from bottom top story.
LKAB Wassara, the Swedish company that develops and manufactures unique water-powered drill systems for surface and underground operations, noted that there are more than 48,000 dams in the world that have a structural height
above foundation of 15 m or more.
The 40-floor tower in the DMCC Free Zone, the largest and fastest growing free zone in the UAE, has a total structural height
of 167 metres.
