Title of the articleTechnical and economic assessment of the concrete’s strength and endurance increasing effect due to the high-strength concrete using for the materials consumption in reinforced concrete frames according to the series 1.020-1/83
Abstract.Problem statement. The purpose of the work is to identify the effect of the concrete strength and endurance increasing in high-strength concrete using on the consumption of steel reinforcement, as well as assessing the possibility of reducing the concrete per set volume to reduce the reinforced concrete frame’s main structural elements cross-sectional dimensions in the series 1.020-83/1. Results. A comparison of the material intensity of the main structural elements of the reinforced concrete frame on the series 1.020-83/1 is made using conventional and high-strength concretes. The calculations were performed for the 1st and 2nd groups of limiting states, both for standard sizes of typical elements and for reducing the cross-sectional dimensions to the minimum possible. Conclusions. The use of high-strength concrete B100 instead of B20 and B30 in the basic structural elements of the reinforced concrete frame on the series 1.020-83/1 reduces the consumption of steel 2 times, reduces the crack opening up to 2 times, and in some cases eliminates the possibility of cracks, and also makes it possible to reduce the dimensions of the cross-section of columns and crossbars, thus reducing the volume of concrete for making the basic structural elements of the frame.
Keywords.high-strength concrete, the expense of armature, a frame on a series 1.020-83/1, columns, crossbars.
