The research investigated the development of a wind tunnel model compared with results of method of\r\ninitial parameters and BS6399 models for dynamic analysis of a multi-storey building subjected to\r\naerodynamic loadings. The dimensional analysis which based its concept on the law of motion and\r\nenergy conservation was used as wind tunnel experimental data assessment tool, for the determination\r\nof the aerodynamic loadings for a multi-storey building. Although, this problem was earlier solved\r\nusing dimensional analysis with different approaches by many Scholars but such solutions did not\r\ninclude an important quantity; the influence of the structureâ��s deflection (d) and foundation infinitesimal\r\nrotation. The study observed that, the non-stationary component is also dependent of the stationary\r\ncomponent of the aero-dynamic force. It also explained how the product of the Strouhal number (St)\r\nand model relative displacement (Lo number), is equal to the Bernoulli universal constant, 0.5. Tests on\r\nmost important parameters capable of influencing the assessment and design of multi-storey buildings\r\nwith varying height-breadth ratio, basic wind speeds, relative displacement and aspect ratio increased\r\nwith logarithmic laws as a function of model height; but the reduced frequency, Etha (???? and Landa (????\r\ndecreased with polynomial and power laws respectively. It was therefore concluded that, aero-elastic\r\ndamping property of the structure is influenced by the Lo number and in particular, ?. Finally, the\r\ncumulative base moment from the mathematical (method of initial parameters) model is 2.108% higher\r\nthan the physical model result and the results from the BS6399 model was less by 1.732%. In general, a\r\ndifference varying between �±2.1% is within acceptable level of deviation for most conventional\r\nengineering and scientific design results.
