Fire resistance of concrete structures: testing using codes of Russia and the USA
Nowadays, it is necessary to pay attention to correctly determination of actual fire resistance of concrete construction and to establishment the possibility of construction further maintenance after the fire. Measure fire resistance of building construction can be performed by experimental methods as well as calculation methods. In the paper, a definition of fire resistance is given, all the basic ways of its determination are listed, the methods of testing to assess the fire resistance corresponding to all the requirements of modern Russian and American requirements are considered, the main similarities and important differences are identified. The general approach in both countries is the same, but there are differences in methodology and constants. Fundamental difference is in design standards due to the fire resistance, from what follows that in the US the focus is on a specific value for the corresponding fire resistance of building structures and only by the desired value their minimum sizes is determined, in Russia, in contrast, the priority is appointment of structure, with which the required fire resistance is determined. With regard to testing, it is possible to allocate the characteristic differences in the number of thermocouples to measure the temperature in the furnace, and on the unexposed surface, in size of the test samples, which affects the accuracy of results and measurements. In addition, the difference in the temperature range of the furnace can be shown, which may indicate that the resulting fire resistance of the same sample with one standard will not coincide with the corresponding one tested with other standard. It should be noted that the requirements for the fire resistance of certain structures by US standards are described in the test methods, but in the computational method, such requirements are not specified. To all other, according to ASTM samples may be tested using hose stream.

The most effective crushing equipment and testing of recycled concrete aggregates
The goal of this research is to study the international experience in managing the construction and demolition waste, to study the methods of testing recycled aggregates for concrete and reinforced concrete in comparison with the Russian practice, and to identify the most effective equipment for concrete waste recycling. Recycling of concrete waste could be the optimum solution for such problems as the lack of space for construction, the exhaustion of natural resources etc. The comparative analysis of the results of different researches showed, that up to 50% of recycled concrete aggregates of total amount of aggregate in concrete mixture has a little effect on the properties of concrete. The recycled aggregates are in demand, because they cost much lower than that the natural aggregates. The analysis of technical and economical qualities of different types of crushers showed, that swing-jaw crushers with their crossfunctionality and power are best for reutilization of concrete and reinforced concrete. Requirements for the type of the crusher depend on the utilization project of the particular building or construction, because each case is unique.

Protecting people from the effects of radon in houses
The article is devoted radionuclides (such as radon). This article discusses the causes of radionuclides and their main sources. It is known that the main sources of radionuclides are natural (70-80%), but without anthropogenic factors radionuclides would not be so dangerous, therefore we consider the reasons of increasing concentrations of radionuclides in the environment, ways of their penetration in buildings and structures, and identifying the most dangerous. Also examines the impact of construction materials on the concentration of radionuclides and selects the most harmless. Based on all of the above features protective measures to reduce the the concentration of radionuclides in the premises, and the various measures to be taken on construction stage and the operation phase.

Single degree of freedom frame structure movements
The article reviews a behavior of statically determinate framed structure (framed one-degree structure) with one degree under different types of oscillation: - free undamped oscillations; - free damped oscillations; - constrained oscillations excluding damping; - constrained oscillations including damping. There are two primary objectives are set in the article. First one is the review of each of oscillations separately, and second one is the investigation of influence of different factors on it. Objectives are solved with numerical method of Runge-Kutta realized on Mathcad software. The comparison and the analysis of influence of coefficient of inelastic resistance of material (or construction) and frequence of external action is based on time-varying concentrated mass movement's diagram foundas a result. External action is harmonic.
