Selection Algorithms of the Optimal Reinforcement for Strength and Crack Resistance of Reinforced Concrete Elements and Their Verification

One of the main stages in design reinforced concrete structures is to determine crosssectional area reinforcement according requirements strength, stiffness and crack resistance, search for number rods based on nomenclature reinforcement, its placement cross section with fulfillment conditions durability, fire resistance. The paper summarizes experience developing algorithms solving problem selecting optimal elements proposes an algorithm optimizing using nonlinear models elements. proposed implemented as a module software package engineering construction calculations Beta 5.0. article shows results verification trial operation within activities Testing Research Center Polotsk State University.
