Abstract

Simple static behaviour of wind loading, which is universally applied to design of typical low to medium-rise structures, can be satisfactorily inappropriately conservative for design of high-rise buildings. This conservativeness could be due to several reasons, and one such factor could be the blind use of analysis and design software's. Most cases the user have little access to the main program frame either for auditing or otherwise. It is highly probable that the resulting outcomes from such interfaces might lead to erroneous results and possible under or over estimations. Additionally, the simplified treatment for deriving lateral loads has issues in addressing challenges such as the effects of resonance, acceleration, damping, structural stiffness, interference from other structures, e.t.c.. These are all important factors in wind design considerations for high-rise buildings. Hence, this paper provides an assessment for high-rise building wind design using both software's and other computation method in exploring gains or otherwise over the simplified approaches of British wind code. The resulting outputs from the use of ETABS and the simplified approach show insignificant variation between them because the p-value from the statistical analysis is less than 0.05.
