NONLINEAR ANALYSIS OF HIGH-RISE BUILIDINGS UNDER WIND LOAD

Abstract

This research is concerned with the study of the effect of wind load on tall buildings. In the study the wind load is dealt with since it is more likely to take place in Sudan and affect tall buildings. The importance of carrying out nonlinear p and p as compered to linear static analysis is studied A twenty story building is analyzed linearly and nonlinearly for wind loads via the commercial software ETABS v13.The linear results are then presented graphically against results of a previous study of a similar building for the comparison so as to check the accuracy of the model. Also nonlinear analysis using p-. And p- With large displacement methods and linear results are compared with each other. The results wear compared for displacement and shear. On bases of these recommendations on the analysis type necessary for tall building subjected to wind loads are drawn. The results shown that the use of the p . with large displacement analysis is important it the correct displacement and shear force are to be obtained
