Design Peculiarities for the Unique Large-Span Buildings and Structures
Department for metal structures
Central research institute for building structures (Kucherenko TsNISK)
Abstract. The article presents an experience of design peculiarities for the unique large-span buildings and structures constructed in collaboration with Kucherenko TsNIISK for the last 30 years. The main stages of design, loads and actions, analysis, scientific and technical investigation, some special problem of design are illustrated.
Key words: unique buildings and buildings of major spans, projection, designs.

Combined (hybrid) arch-cable structures. Numeric and experimental researches
Department for metal structures
Central research institute for building structures (Kucherenko TsNISK)
Abstract. The most interesting examples of the combined (hybrid) arch-cable structures, the principle characteristics and schemes are presented. The comprehensive researches of the combined arch with reference to the roof for “Gostinniy Dvor” complex in Moscow were carried out in TsNIISK. Theoretical and experimental results are presented.
Key words: combined (hybrid) arch-cable structure, geometric non-linearity, mounting stages, pre-stress, large-scale model.

Toxic Effluents of Gas Pipe Heat Generators of Independent Heat Supply Systems under Gas Fuel Burnsng
Donbas National Academy of Civil Engineering and Architecture
Abstract. The problem of effluents from the gas pipe heat generators of independent heat supply systems is considered in the paper. The typical factors affecting the formation of harmful effluents are analysed, the measures on reducing effluent concentration in smoke gases passing from heat generators are recommended.
Key words: effluent, gas pipe heat generator, nitrogen oxide.

Analutical models of “ag е ing” and economy of maintenance of shielding structural members leaf of constructions (on an example of steel containers)
Pridneprovskaya State Academy of Civil Engineering and Architecture
Abstract. The degradation processes and definition of durability of sheet structures guarding constructions is examined by steel tanks. Local refusal that can be removal and common refusal are distinguished. Technical resources exhausting criterion is accepted the totality of defects and damages in structures. Some economic aspects of such approach are considered.
Key words: corrosion, corrosive wear, defects, damage, time to failure, durability.

Wind loads on low buildings in a built up area with a tall building
Donbas National Academy of Civil Engineering and Architecture
Abstract. The paper presents one of the problems of town planning which is considered the densification of the five-story buildiry area with a high building. The results of the wind tunnel experiments an determined wind loads on low buildings due to the effect of a high building.
Key words: wind loads, wind tunnel, interference effect, high building.
