Evaluation Of Multi Storey Structures In Malaysia

Malaysia has not traditionally considered earthquake and hurricane loading in design.
Several tremors in neighboring countries necessitated a relook at the seismic reliability of structures
in Kuala Lumpur and Penang with significant seismic risk. The study started with simple vertical
load analysis (the current practice) and then the earthquake and the wind loading were imposed. The
integrity of structures was evaluated for serviceability deflections using UBC 1997, IS 875-3-1987
and IS 1893. Permissible deflections were exceeded at 40 m/s for 87 m height buildings; at 45m/s
for above 70 m height buildings; at 50 m/s for buildings above 59.5 m height. Higher value of
ground accelerations (>0.1 g) results in exceeding the serviceability deflections
