Item Method of Calculation of Temperature Field and Deflected Mode of Bridge Structures in Software Environment NX NASTRAN(Szcześniak, Warsaw, 2013) Luchko, Josyp; Hnativ, Yuriy M.; Kovalchuk, Vitaliy V.EN: Abstract: Designs of bridges and overpasses during operation are sustained to complex climatic factors. Study of heat exchange components is an integral part of preparation data for thermal stresses and deformations calculation. Sequence determination of thermal stresses and deformations of bridge structures. Close conditions of the structural elements of modern bridges and overpasses, a variety of their shapes, materials and sizes result in extremely difficult and expensive full- or part-scale investigations. In this regard, there is need to develop and apply various computational approaches that allow relatively in a short time and with little cost to obtain data about engineering structures.
