“…In the supports the most common used a cross-lattice with combined nodes in adjacent faces, the elements of which are made of single rolling corners connected to each other along one shelf on bolts. The nodes of braces abutment to the chords in such lattice are obtained not centered because the braces geometric axes are not aligned with the axes of forces passing through the braces [8][9][10]. The resulting bending moments predetermine the early development of plastic deformations [11,12,[23][24][25][26].…”

An article compares the theoretical and experimental researches of joint work of steel tower type supports' fragments of overhead power transmission lines (OHPL) 110 kV. Attention is focused to high voltage supports operated on the Ukraine territory. Is described a spending principle of static experimental researches for flat trusses on the developed specialized experimental installation, allowing to investigate the joint work of overhead lines supports' fragments. Are presented the technique and results of the flat support model calculation in the "SCAD" software package. Are presented calculation numerical results of the experimental installation together with a testing model. Are determinated experimental values of stresses in lattice elements and also horizontal and vertical displacements of braces holding on nodes. During the displacements determining is analyzed the joint work of the lattice elements of the experimental samples, is taken into account the supporting effect of the extended braces.

Aiming at improving the low efficiency and inaccuracy of the traditional thunderstorm prediction model, a paralleled and improved naive Bayesian thunderstorm prediction model SPNBC is proposed. The native Bayesian classifier (NBC) model assumes that the attribute data set is independent, which leads to inaccurate prediction. The principal component analysis algorithm is used to optimize the Bayesian algorithm to build PNBC. First, a new attribute data set is constructed by the principal component analysis (PCA) algorithm to eliminate the dependency between attributes, and a naive Bayesian classifier is constructed on the new attribute data set. Secondly, SPNBC is obtained by parallel design of PNBC based on spark framework to improve the time efficiency. Finally, taking the thunderstorm prediction in Hohhot as the application background, the accuracy rate, false alarm rate, speedup ratio and scalability ratio were used to analyze the experiment. The experimental results show that the SPNBC of this paper is better than the traditional naive Bayes algorithm and neural network algorithm, and the prediction accuracy rate and empty alarm rate are larger when dealing with massive data Performance advantages.
