To investigate the effective structural system for high-rise building design of height between 200m to 250m and subjected to wind conditions in KL city centre

The design and construction techniques of tall building structure have been evolved and
improving throughout the past. In today's modern world, improvement on construction
materials, development of new structural systems and the usage of structural software
have all significantly contributed to the effectiveness of tall building design.
This analytical study was carried out to investigate the influence of various parameters
on the design of tall building structures of 200 to 250 m height. The influencing
parameters include the effects of various concrete grades, such as grade 50, 60 and 80 as
well as effectiveness of the structural system based on rigid frame system and the shear
wall system. The analysis was carried out using structural software STAAD.PRO 2002.
Based on analytical and structural design results as well as obtained from computer
analysis, higher concrete grade resulted in appreciable reduction in the vertical member
sizes such as column dimensions and the shear wall thickness. Although analytical
values ofmaximum drift at the roof level was obtained within permissible limit for rigid
frame, however shear wall structural system has shown a lower value of the maximum
drift at the roof level. In studying the shear wall system, three different configurations
andarrangement of walls were considered, which also affected themaximum drift.
