Modeling of a deflected mode of tower structure bearing flanges for an intelligent design
Abstract: There is considered an analytical and numerical modeling of a deflected mode of metallic tower structure bearing flanges with the use of the up-to-date program complexes “Lira 9.4” and “Cosmos-Works” to rationalize their design. A real tower as high as 60 m being taken as an example, numerical results obtained with the help of “Lira 9.4” and “Cosmos-Works” were compared. The numerical methods realized in the program complex “Cosmos-Works” prove that a joint work at modeling structural subunits as well as redistribution of stresses which occur in welded joints make it possible to reliably estimate real stresses in a flange which turned to be much lower than those estimated analytically, and, as a result, to considerably lower its thickness.
Keywords: tower telecommunications structures, flange joint, deflected mode, reduced stresses, intelligent design.
