Journal Title: Металлические конструкции - Year 2018, Vol 24, Issue 1
Abstract
The analysis of the stress-strain state of dead-end OPTL support which is considered as spatial repeatedly statically indefinable through system with rigid joints is performed. The technique and results of calculation of spatial model of a support is resulted in a software package «SCAD». Some questions, connected with specified definition of the internal longitudinal forces in elements of OPTL support’s construction are considered. During calculation teamwork of lattice elements of spatial model of a support is analyzed. On the basis of calculation and generalization of results detailed comparison of the received internal efforts with the efforts defined in elements of typical OPTL support from identical values of loadings is executed. It has been given the schemes of the optimized double-circuit OPTL supports 110 kV. There was made a comparative analysis of the masses of typical and optimal corner dead-end supports U110-2 with zinc coating and without it. Results of researches have been introduced at manufacturing, installation and operation of optimal tower support.
