A METHOD TO DETERMINE THE EFFECTS OF NONUNIFORM TORSION ON TALL BUILDINGS
Abstract :
In this paper, a method is presented to determine the effects of Vlasov nonuniform torsion caused by horizontal loads on structural systems of tall buildings. In this method, a realistic assumption is made that the variable horizontal loads act at each story level instead of a uniform lateral load along the height of building. For the presented method, an algorithm is prepared in software MATHCAD in which the cross-sectional characteristics are calculated and the sectorial coordinate diagram is plotted. The results can be obtained in a short time, hence it is not needed to solve the time consuming differential equations. The method is compared with the studies of Taranath and Smith Coul, and is also compared with the softwares ANSYS and CONSTEEL by modeling as a cantilever beam to check the accuracy of the algorithm.
