DYNAMIC ANALYSIS OF TALL BUILDING UNDER PULSATION WIND EXCITATION

This paper presents analysis of tall building under wind load excitation taking account of pulsation. The path of the analysis using MatLAB, Lira and Russian national code SNiP are presented. Use of wind velocity-time graph is employed where the change in wind pressure (pulsation) with time is assumed to be proportional to a similar change in wind velocity. Results are compared and show a conformation to dynamic behaviour of the buildings under such excitations as pulsation, thus making the analysis adequate for assessing the dynamic behaviour of a structure.
