The kinetics of curing of concrete at an early freeze
One of the most important materials in modern construction is concrete. The article investigates the effect of freezing on the kinetics of early strength development of concrete. At the moment the construction process in the winter is a difficult task faced the industry professionals. Because of the cyclical processes of freezing and thawing, as well as due to the low temperatures, the hardening rate and the quality of concrete blocks is reduced, which creates a threat to the project under construction. To study this process made several series of concrete samples in the amount of 18 pieces of sizes 100h100h100 mm with different water-cement ratio (the W/C) and the hardening conditions. Control samples hardened in the standard normal conditions, and the major parties undergone early freeze in a freezer at t = -20°C, then to test the samples are stored with the inspection parties. The same was done with the samples with the other water-cement ratio. Compressive Tests were carried out at 7, 14 and 28 days. The results are presented in tables and graphs, the analysis of which you can make certain conclusions, according to which the concrete of the major parties are losing a small part of the strength, but have a tendency to set up its further alignment with the control parties.

Rational geometric and stiffness parameters of long-span structural roof
This work is devoted to solving the actual problem - the spread of well proven standard solutions structural designs for bridging non-standard plans based on the finding of the geometric parameters of a typical cell coverage, which could meet the maximum load capacity of high-strength bolts 40X "SELECT" (100 m), which is one of the main types of structural elements of the Moscow Institute of Architecture and limiting its load-bearing capacity. The object of research, in this case, a regular structural design of the Moscow Architectural Institute at unconventional plan 68,4h45 m. To solve the above problems in using both analytical and numerical methods of calculation. Analytical calculation method based on the theory of bending of thin slabs and is carried out in accordance with the method proposed in the work AG Truscheva. Numerical studies were performed using the software complex «SCAD», which established finite element model of the design, explore further the case securely fastened on a path to consolidate and different variations of geometric shapes cover (from the flat geometry of the structure to reverse dish of structural slabs to form a shallow shell) . As a result of the research, the following results: 1) analyzed the plan cover (a: b = 1,6: 1), with a load of q = 263 kg / m2, the limit value for h / l, in which the possible use of standard system components MARCHI there h / l≈1 / 17, which is somewhat different from the traditional recommendations for appointment of h / l for structural coatings (1/15 ... 1/30); 2) at the transition from the flat circuit to the space, in the form of a shallow shell fixedly attached contour required value dish of primary boom, whereby it is possible to use standard type elements MARKHI is f / l≈1 / 27; 3) The results of the study of stress-strain state (SSS) of the structure obtained in the case of the return of dish plate showed that this method is an effective method of controlling the parameters of the VAT provided fixedly mounted on circuit design. The results obtained in the course of research, have practical importance, as because of their use may theoretically justified the appointment of rational geometric parameters of the projected structural design of coating on the initial design stage.

Bridge spans with corrugated steel webs
The article is devoted the new constructive solution for the design of composite and metal bridges based on the use of corrugated steel webs. The novelty of the design solution is based on the replacement of a flat concrete or metal web on corrugated steel web. Local sustainability is increases in such webs by giving spatial form. The analysis of national and foreign literature is performed. It is noted that nowadays there is no research about bridge spans with corrugated webs in our country. The classification of bridges with corrugated webs is given. In conformity with this classification the examples of built bridges all over the world are given. Prospects for further development are devoted. According to the analysis the main conclusions are: the applying of corrugated webs in steel-reinforced concrete span structures of bridges increases the efficiency of the use of prestressed concrete and reduces the metal of the bridge structure by 15-25% and reduces labor costs by 15-20%; the applying of corrugated webs in steel span structures of bridges can improves the stability of the web by 20-25%, which gives an advantage in the manufacture and installation. World experience of research and building construction shows that the bridge spans with corrugated webs meet the criteria of rigidity and load bearing capacity of building structures. Large volumes of construction confirm the relevance of this subject for research.

Acoustic characteristics of foam polypropylene as an example of vibration and sound isolation material Penoterm Penoprof NPP LE
Requirements of consumers for housing conditions increase every year because of what there is a need for ensuring the good sound insulation of rooms. Now the given problem is solved by the use of vibronoise-insulating materials as a part of multiple floor coats, which reduce the level of shock noise and provide necessary acoustic comfort for buildings of the modern city. The results of laboratory researches on definition of dynamic characteristics of a frothed penopropilen Penoterm PenoProf to NPP LE 10, 6 and 5 mm thick of the company "Penoterm-Urals" are presented in the article. Based on the data obtained by practical consideration indexes of improvement of level of shock noise were calculated. The results of the tests revealed that the physical and mechanical characteristics of the sample 10 mm in thickness better than samples with thickness 5 and 6 mm. Also was the comparative analysis obtained by calculating the index of improvement of level of shock noise with indicators of the soundproofing materials of other firms and found that the performance of different materials are roughly in the same range, but in varying degrees of change over time.

An arch multipurpose modular design
In the present article, it is offered to examine a new design - "An arch multipurpose modular design" (AMMK). Multifunctionality of this design assumes use it for construction of wide-span buildings and constructions, tanks, ski jumps, bridges and elevated crosswalks. Besides, AMMK can be curved as in one plane, and to have a design bend in several planes. The design elements working for stretching are executed from cables. The elements working for compression represent volume small-sized modules. Such modular system of AMMK, allows carrying out delivery of a wide-span design without use of special equipment on any building site. Besides, the geometry of this design can have double curvature. "The arch multipurpose modular design" has small metal consumption in comparison with classical schemes of arches and farms, and allows reducing considerably time for delivery and installation of a design on a building site.

Optimization of parking space in the conditions residential area
In the conditions of the constrained housing estate, the problem of shortage of parking spaces is particularly acute. Lack of a place on specially allocated areas for the parking of an individual transport makes negative impact on both the environment and the quality inhabitants’ life quarters. Cars park on lawns, territories of rest and near them, that complicates the movement of pedestrians, and in most cases, journey of cars. Deficiency of parking spaces puts a task of integrated parking management solution. One of solutions of this problem is the construction of the leveed parking. In the article the project of leveed parking within construction of a residential complex with a choice of optimum option of the organization of parking space, as well as expediency of use of this type of underground and above ground parking lots in residential areas.
