The paper builds three oscillating models of high-rise buildings. The first problem is to study the model of a 3-storey building which is a elastic system that fluctuates freely under the effect of self weight. The second problem studies the horizontal oscillation of a 3-storey building when the wind force is a function of harmonic F(t)=F0sinWt effect on the top floor. The third problem is studying the small fluctuation of a 2-storey building composed of 3 blocks placed on elastic ground subjected to earthquakes, causing horizontal vibration foundation u(t)=u0sinwt. The results of the article tell us the horizontal oscillation of the building under the effect of wind forces, earthquakes and also the direction for our further research ER -
