| Title of the article | The use of high-strength concrete B80 for the frame of an 18-storey residential building in the «Salavat Coopere» complex |
| Abstract. | Problem statement. The purpose of the study is to identify and evaluate the possibility of efficient use of high-strength concrete, manufactured primarily from local building materials, in housing construction. To assess the technical and economic efficiency of the use of high-strength concrete, «GVZhF RT» asked KGASU to redesign the frame of a monolithic 18-storey residential building with the use of high-strength concrete class B80. The basic carrier system was designed from concrete of class B25 by the institute of «Tatinvestgrazhdanproekt». Results. The main results of the research consist in the development of an improved bearing system of an apartment house with the use of high-strength concrete, which, relative to the basic frame, allowed increasing the pitch of the columns, reducing the number and dimensions of the cross-section of all load-bearing elements. The economic effect of reducing the consumption of materials amounted to: 4,47 million rubles, or 13,5 % of the cost of the frame when using concrete grade B80 on granite gravel, and 5,89 million rubles, or 17,7 % – on the Kama sand. Conclusions. The significance of the results obtained for the construction industry consists both in confirming and in assessing the effectiveness of the application of high-strength concrete of the B80 class. The use of high-strength concrete, in the example under consideration, made it possible to: facilitate the building, increase the pitch of the columns, reduce the amount of construction and installation work, increase the useful area of the premises, and add a parking lot to the underground part. |
