USE OF HEAVY DUTY CONCRETES AND REINFORCEMENT IN DESIGN OF PREFABRICATED AND MONOLITHIC REINFORCED CONCRETE STRUCTURES
The article represents a summarized overview of a generalizing approach to optimized use of high-strength concretes and several effective classes of reinforcing steel in bendable reinforced concrete elements. The assessment made by the co-authors is based on the criterion of reduced consumption of reinforcing steel and concrete. The rate of effi ciency of use of high-strength con-cretes and reinforcing steels in bendable (slab) elements is assessed in the article. The principle of selection of optimal thickness of monolithic fl oor slabs based on their cost and material consump-tion rate is proposed. Economic and mathematical methods were used to develop the method-ologies and algorithms proposed by the co-authors. Their methods were implemented in software programmes registered by the Federal Service for Intellectual Property of the Russian Federation. The software optimizes the analysis and the process of design of the monolithic reinforced concrete framing. The results of the research were applied in design of several structures in Ufa.
Key words: girderless concrete forming, defl ected mode, bearing capacity of a fl oor slab,
high-strength concrete, bendable reinforced concrete elements.
