Abstract

The impacts of the dynamic properties of wind and earthquake on the response of a newly designed 39-storey reinforced concrete (RC) tall building in Kuala Lumpur, Malaysia are investigated. Samples of several types of structural members were chosen in a lower level to represent the steel to concrete ratio (AS/A, ) as a technical-economical indication of the project. These are two rectangular columns (one at the side 1.000 x2.200 m and another near the middle 1.000 x l. 600 m), a beam near the middle 1.000x0.700 m, and a 350 mm shear wall. The commercial structural analysis software, ETABS, was applied to simulate the response of the building to a potential local earthquake. Structural analysis was based on the British Standard BS8110 using Response Spectrum Analysis (RSA). The response of the building to a range of likely wind speeds under ultimate load combination was also simulated using the same software. Representative responses were then monitored: maximum horizontal displacement at the top corner of the building, AS/ACa, nd peak accelerations. As for the wind, equating the maximum roof displacement to that of a hypothetical equivalent cantilever beam, a linear relationship for the equivalent modulus of elasticity of the tall building, Eeq, is found. It is shown that such parameter could be used for a quick calculation of maximum roof displacement of various structural systems for tall buildings. Various plots of the response of the structure to earthquake and wind will provide for insight into the sensitivity of the design to seismic and wind loading. They can be used in the conceptual design of the building where quick technical and economical comparison of numerous alternatives is often necessary. The findings could disseminate the recent awareness caused by the Sumatra earthquake (December 2004) among design engineers of high rise buildings
