Study of spatial operation of the lattice cross components in full-scale tests of an optl support on the testing ground of DonNACEA
Abstract: There is given a design procedure of definition of central displacements of metal dead-end supports of overhead power transmission lines (OPTL) in full-scale tests on the testing ground of tests of overhead power lines and tower structures of the Donbas National Academy of Civil Engineering and Architecture (the Testing ground of DonNACEA). There is analyzed a mode of deformation of an OPTL support U220-2+9 which is considered as a spatial multiple indeterminate open system with flexible joints. There is given design data of central displacements of working and non-working support faces in the software package «SCAD». In definition of central displacements there is analyzed a joint operation of the lattice components of an OPTL support, supporting influence of the stretched lattice diagonal element members is taken into account. On the base of received results there was thoroughly compared the experimental values of central displacements of the second panel from below and the ones specified in the software package «SCAD». The given technique enables to define the central displacements not only for OPTL supports but also for the antenna supports and open switching centres to check the deformability of construction in normal and emergency operating modes.
