Abstract
Technical and economic indicators of the proposed solutions truss reinforced concrete beams with a combined pre-stress
Incoming article date: 21.06.2016The article presents the technical and economic indicators previously proposed solutions truss reinforced concrete beams with combined prestressing. Reducing consumption of concrete and steel in comparison with typical. This reduces the weight of the beams and money. Significant economic effect is achieved by the use of roof beams t profile with a shelf in the stretched area. This effect is achieved due to a significant reduction of the structural height of the coating (beams and slabs). By reducing the volume of the brick walls of the building, which is based on the overlap, the cost of masonry with single-span building, as noted above, reduced by 33% in comparison with a standard solution.
