Recently, the issues of evaluating the quality of building structures and predicting their reliability are becoming increasinglyimportant, especially for the construction of industrial facilities of the old fund. Powerful mathematical methods are beingdeveloped to evaluate the performance of structures and predict their reliability, but there are no automated computer systemsfor such analysis. At present, programs for the determined calculation of structures have been developed, which implementmethods for the resistance of materials, theoretical and construction mechanics, but they do not provide an opportunity to determineand predict reliability, especially objects of the old fund. The methods of the classical reliability theory combinedwith the methods of statistical modeling are used in the work, which requires the use of modern IT technologies methodswith the development of appropriate software systems

Based on the previously described mathematical model implemented in software complex PLASTICA, nonlinear calculation of one anchor sheet pile wall together with surrounding soil medium has been performed. To assess the results reliability with experimental data tests Lazebnik G.E., calculations in PLAXIS 2D and classic Coulomb method are compared. The basis of a mathematical model incorporated the theory of plastic flow with hardening, which is based on the principle of maximum Mises. In general, it can be assumed that the calculations results in the software package PLASTICA using the proposed nonlinear models showed satisfactory agreement as compared with the experimental data

In the article presents an engineering method for calculating compressed flexible reinforced concrete elements with sheet reinforcement over a steel cross section. The results of the calculation are compared with the experimental data. Calculation ofload-bearing capacity of reinforced concrete flexible elements with sheet reinforcement is based on the method of boundarystates. The work of specimens under load and the nature of the load-bearing capacity depending on the height and eccentricity of the effort were investigated. The proposed method of calculating compressed elements with sheet reinforcement on asteel-cross-section allows to take into account their flexibility in both axial and out-of-center application of load.

The article is focused on the natural experimental research of injection waterproofing impact on basement areas of existingbuildings brick walls. Two types of experimental installations for waterproofing material injection have been developed. Thesecond type turned out to be more efficient due to the fact that it could cover larger waterproofing wall area. It can possiblyspeed up the process of walls waterproofing and major repairs of buildings in general. According to the experimental data, after the injection waterproofing placement, the wall moisture content decreased by half due to the high quality waterproofingmaterial and performed installation work.
