Yuri Kondratyuk Tkachenko Iryna Vitr.IV@i.ua Improvement of the methods of placing elements of highways beautification Modern road environment of Ukraine is characterized by random placement of beautification elements; therefore, there is need of improvement of the methods of their placement in view of modern conditions and requirements. The work is contains the systematization of factors that impact on the perception of the road environment by driver and passenger. The authors offer method of placement of beautification elements by the principle of spatial corridor. They have developed the model of spatial corridor of automobile road for placement of beautification elements, which have divided on the four sub-corridors in accordance with the level of importance. In the article determines parameters of the spatial corridor of the automobile road, such as width, height and length according to the optimal perception the road environment by driver and passenger. The proposed principle may be used by designers and students in the design of automobile road beautification. 10.18720/CUBS.3.1 69 beautification of automobile road spatial corridor perception highway environment https://unistroy.spbstu.ru/article/2012.3.1/ 1_litvinenko_tkachenko_3.pdf

It is set an example of calculation in which comparison of the decisions received by methods of F.Engessera, T.Karmana and I.Tsurkova which involves laws deformation theories of plasticity is resulted. Ultimate stress which was determined on resulting module, gives superior limit of stress for load capacity of a design, on tangent module – limiting minimum, stress, on module Tsurkova it located between these solutions. 10.18720/CUBS.3.2 69 critical load ultimate stress stability load capacity design module https://unistroy.spbstu.ru/article/2012.3.2/ 2_rahimbekova_hasenov_3.pdf
