The economic feasibility of using green roofs in the reconstruction of buildings
The rational use of energy in buildings is achieved starting with the design stage of them. The use of energy-efficient and energy-saving technologies in the project in many ways reduces the energy consumption of buildings and save money on heating costs. One of the possible solutions to the energy-saving of buildings and structures is the application of green roof technology. Taking into account the thermal, economic, ecological, social, constructive advantages of the green roof technology with a competent economic approach it is possible to recoup the erection of the roof. The purpose of the research of the master's thesis is to develop of methods of reducing the payback period for green roofs during the reconstruction of buildings using the example of budgetary and private institutions. Despite the large number of publications on this subject the problem of the recoupment of green roofs remains relevant for further study.

Breakwaters with protective filling
Trouble-free operation of marine hydraulic engineering structures installed in various climatic conditions of Russia depends on the accurate and reliable methods of their design. Reasonable choice of design solutions will optimize the value of the projected structures and ensure their safety, both during construction and operation. The objective of this study is to compare the different options of designs of breakwaters with protective filling. The following variants: sloping type of riprap; the shells of large diameter or double-row design with protective filling from seaside are considered. The common element for all variants – riprap or concrete block filling, designed to protect the foundation from scour and reduce the loads from wave action. The schemes of listed above structures of protecting structures, methods of its calculation and design are examined. Based on the comparison of variants the most economical and safe design will be offered.

Deformation of concrete creep in the thermal stress state calculation of massive concrete and reinforced concrete structures
In general practice the calculation of thermal fields is often based on the heat equation solution as well as thermal stresses definition, linked with calculation of cracking resistance massive of concrete in construction period. A change in the thermal state of such structures occurs due to the heat liberation from cement hydration during the concrete hardening process, as well as outside temperature fluctuations, solar exposure, various technological factors, etc. Emerging thermal stresses may cause damage to the structural integrity. Calculation of thermal stressed state of massive concrete structures in the building period and value of cracking resistance are hard enough with a practice and engineering point of view. Some researchers close to solution of these problems in a simplified variant. The purpose of my thesis is creation of a method that could be consider the modern normative data about degree of a creep in calculating thermal cracking resistance massive concrete and iron cocnrete structures in a building period.

Pushover Analysis in progressive collapse of buildings and structures
Pushover analysis is a nonlinear static method of analysis of seismic resistance of buildings and structures, in which the seismic load is gradually increasing to determine the pattern of distribution of forces in the structural elements of the building, as well as the nature of the oscillations of its upper point. The result of the calculation is the family of diagrams at different levels of the seismic load. In calculations for the progressive collapse, the method is applicable: for the preliminary determination of the "weak points" of the structure; to calculate the seismic stability of the model obtained according to the results of calculating the progressive collapse

Gates of the Dry dock for construction of large-capacity vessel
Flap gate is a shield that pivots on two pivot bearings about a horizontal axis, is located near the threshold of the head section of the dock. In general, the gate is loaded lateral load, which does not coincide with the resultant of the direction of the principal axes of inertia and does not pass through the center of curvature (or stiffness centers), coinciding with the centers of torsion. Therefore closures are almost always on the oblique bending and torsion constrained. In this regard, the task of calculating the shutter, after bringing the load to the axis stiffness, is divided into two: the shutter calculation for oblique bending and calculation of constrained torsion moments that arise when the ghost said. If the bolt is long enough as compared to the cross-sectional dimensions, the calculation is performed on the oblique bending on the well-known formulas of strength of materials; at a small gate to the flight height of the section is necessary to consider the impact of changes. The paper proposes an approach to solving the problem is not associated with any arbitrary simplifying assumptions, except the assumption of non-deformable shutter profile as a thin-walled bar.

Automated Checks of the Building Information Model for Regulatory and Technical Documentation
A computer prototype of a building object makes it much easier to work on a project at any stage of the lifecycle: through automation, computer analysis, mathematical data processing. In particular, at the stage of project management, the use of the information model makes it easy to verify the quality of design decisions. The research provides types of automated checks and attempts to classify them: checking the quality of the model, initial checking of design solutions (searching for geometric and so-called "intelligent" collisions), checking the model's changes over time. Then there are types and examples of checks on real projects, some ways to develop them. In the end, a conclusion is drawn about efficiency of automated checks.

Implantation of an artificial ice island to the bottom of the Kara sea
There is an intensive exploration of the Arctic nowadays. One of tasks is the building of off-shore structures for exploration drilling for searching of natural resources, such as oil and gas and for geological, seismic and meteorological studies also. Building of various structures is required for im-plementing of these operations. For selection the most biodegradable and economical solution was made the comparison of classic proven offshore structures. Artificial ice island was chosen on the basis of the obtained data. The process of building includes great number of operations, requiring computational reasoning. Questions connected with the shift of planted ice island from the action of horizontal loads are analyzed in this investigation. The results were tasked to conduct further research.

The sheet material in composite wooden beams
The actively developing market of timber construction requires modernization, invention and implementation of modern materials and new basis of design. One of the most promising solutions for structural elements of timber structures are I-beam and tubular girder sections. In the work, beams are considered box-sectioned, the belts of which are made of solid wood, and the walls of oriented-strand boards. A comparative analysis of the stresses calculated by the domestic standard method and obtained from the solid finite-element model in the PC Lira is presented. In the calculation with software complex, the anisotropic properties of wood and OSB are taken by specifying the orthotropic properties of materials.
