Effect of Differential Movements of Foundations on Behavior of Lattice Towers Supporting Chimney
Abstract: The effect of ground deformation on stresses and strains in steelworks is dealt with in the paper. The steelworks include lattice towers for supporting steel chimney. The deformations of ground are modeled by inducing differential movements of a separate foundation in vertical and horizontal planes. The internal forces in tower members due to movement are calculated. The most widespread types of towers of 115 and 140 m high supporting exhaust pipes and chimneys and having square and triangular layouts with individual foundations are adopted as the object for research. The calculation model of the towers is a space truss. The qualitative parameters for the influence of uneven soil deformations on normal forces into the tower members are obtained and analyzed. On the basis of numerical data received the simple model are proposed for calculating additional forces arising in the elements for towers up to 150 m high. The technique of applying the model for towers designed under different wind conditions is outlined.
