WERYFIKACJA STATECZNOŚCI KONSTRUKCJI STALOWYCH KRATOWYCH SŁUPÓW ELEKTROENERGETYCZNYCH LINII 110 KV

Abstract

In the work one made sensitivity studies the relative effective slenderness on the compression capacity of the elements used in steel lattice–towers. The effective slenderness is counted with the regard of the type of of the end connections of the elements. One discussed the implementation of these rules of calculations in reference to new tower of overheading power lines 110kV. The verification of foundations of theoretical calculations of the capacity of elements of latticed towers one carried out during tests of complete constructions on the field tests. Tests were driven within the framework of the realization of the project partially financed from measures of the of the European Fund of the Development of the Regional Province of Mazovia No. RPMA.01.02.00–14–5672/16. Results of tests confirmed with the large accuracy the conformity of the estimation of the theoretical capacity of elements with the really designated limit capacity of systems lattice–tower, consumable as result of the loss of the stability. One confirmed the practical effectiveness of standard procedures contained in standard PN–EN 1993–3–1 within the range the modification of the dimensioning of compressed elements with constant cross section. For purposes of the article was the indication of the efficiency of innovative rules of calculations of lattice–towers systems providing the appropriate compression capacity of elements at the regard of economic aspects of solutions.
