Contract organization of project finance allow to reduce the asymmetric information, limiting the possibility of opportunistic actions of each participant. The back-to-back principle, that is underlying for contractual arrangements, increases total project return and provides transfer and split of highest possible number of risks directly to the contractual counterparty, which is best suited and have the most appropriate instruments to cover this risks. Tripartite deeds of project financing can be considered as a cooperative non-zero sum game, which provides compensation in proportion to covered risk and member's contribution (extent of assumed obligations or provided funds). Multiple contracts of project finance initiatives allow to allocate risks pro rata the ability of participants, without reducing the amount of final win of all parties.
Keywords: project finance, project financing risks, asymmetric information, agency theory, contractual arrangements, back-to-back principle, concession agreement, purchaser contract, tripartite deed, game theory
Requirements for methods of diagnosing design increases - they should make it possible to fully assess the performance of buildings, as well as being simple and mobile, to be used during the construction, operation, maintenance and reconstruction. This work is devoted to the realization of experimental and theoretical methods for vibration monitoring of structures and the analysis of the results. The objects of study are the reinforced concrete beams and slabs, and the subject of the study - the methods of vibration diagnostics, the principle of which is to detect changes in the construction of the main dynamic characteristics. Research has shown that damage to the structure can be detected by the methods considered, using a relatively small number of monitoring points and subject to change only the fundamental mode of vibration.

Given the task of calculating the stresses in the radiation-thermal plant screen. This design, also known as «dry protection» is intended to reduce the effects of radiation and heat, generated in the reactor. A significant redistribution of stresses due to changes in elastic modulus due to the above effects.
Keywords: thermal loading, loading of radiation, the calculation of protection for accident-mode for trouble
Mathematic model considers the geometrical and physical nonlinearity, the adaptability of creep flow. Arc work is accounted for by the method of constructive anisotropy, but with due regard for shear and torsion rigidity. In solving physically nonlinear problems, secant modulus is defined directly from the «σ-ε» curve, found experimentally. Mathematic model is written in the form of functional of total deformation energy. This model can be used for comprehensive analysis of the stability of reinforced shells of revolution.
Keywords: stability of reinforced shells of revolution, linear-elastic problems, the nonlinear-elastic problems, the problem of creep flow.
The article summarizes the possible changes in the nature of mudflow activity on the basis of projected changes in the natural environment. Proposed main areas of further study of the mud and prevent mudflow threat, organizational, economic, agricultural and technical measures of protection against floods, weakening the mudflow activity in mountain areas from floods, warning seleopasnost′ and protecting from mudflow threat. The article contains. Bibliography-3 title.
Keywords: torrents, mudflow activity, protection measures against floods
Article is devoted to transformation of the concept of a risk management to the tasks of management by development of city territorial systems. The generalized schematic structure of risk management of development of the urbanized territories is considered. Need of the accounting of economic, ecological and social consequences of administrative decisions in the course of realization of strategy of development of territorial systems is substantiated. The mechanism and algorithm of formation of predictive integratedestimateof quality social-ecological-economic system as a result of realization of strategy of the development is offered, allowing essentially to reduce quantity of analyzed options of operating influence.
Keywords: development management, territorial systems, risk concept, risk management, integrated estimate
In the article the imitating system of a perspective plan of the housing renewal, developed by the author, including dynamic model of the housing technical condition change, model of financial support for the realization of a perspective plan, optimization model of the housing renewal perspective plan is considered

In article bases of a methodical approach to improvement of the organization of labor protection in the construction, based on a position of system risk management are considered. The methodical approach unites the block diagram and risk management model, provides efficiency of management of production safety, development of purposeful actions for decrease in risk factors, to elimination of the found violations of labor protection and their prevention further.

It is shown that to describe the phenomena and processes in a transition interfacial layer having a certain thickness, it is useful to distinguish the boundary layer of the surface and boundary diffusion layer, which lies entirely in the less condensed phase related. In accordance with this energy and power characteristics of the transition layer should be attributed to the boundary surface of the interphase transition layer. The basic equation of electro capillary boundary of the surface layer, establishing the dependence of the surface tension of this layer on the chemical composition of the second phase, and bordering the jump of electric potential between them.
