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.

Stability behind the limit of elasticity
Generalization of the formula of Euler on not elastic area and definition of critical force in the compression member behind a limit of elasticity is considered in article. 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.

Footway bridges: cold formed steel cross-section
Structural bridge’s types: 1. Beam span; 2. Frame, arch, suspension and cable-stayed bridges Materials: 1. Reinforcement concrete; 2. Steel (hot-rolled cross-sections) 3. Steel (cold-formed cross-sections) Base difference of thin walled from thick-walled cross-section is concluded in behavior laws: breach of Bernoulli (plane-sections) hypothesis. Simple example is I-section deformation, when the last is loaded on end by bimoment. Deviation from Bernoulli (plane-sections) hypothesis is more characterized for open then for closed thin walled cross-sections. This is taken into account in non-linear analysis of pedestrian bridge structure. Besides analysis according to 2 rd order theory also non-linear material models for metallic materials is considered. The applied elastic-plastic-zone theory is based on the interaction of any internal forces and moments.

Increase of power efficiency of buildings of kindergartens
The analysis of results of power inspections and search of possible solutions of energy saving and increase of power efficiency of budgetary organizations (kindergartens) taking into account feature of these objects and justification of their economic efficiency is given in article. Calculation of payback periods of the energy saving actions directed on increase of level of thermal protection of external enclosure structures of buildings is given. Economic efficiency of investments in energy saving actions is analyzed and the model allowing to carry out the specified analysis is offered. Recommendations about reduction of payback periods are provided. Article also is devoted definition of optimum, economically well-founded thickness of an insulant in systems of rear ventilated facades. Are resulted thermotechnical and economic calculations.
