Simulation of Design Reliability and Bearing Capacity of Normal and Oblique Sections of Span Prestressed Reinforced Concrete Structures

Abstract:

The paper studies the influence of various constructive factors on the parameters of design reliability and bearing capacity of span prestressed reinforced concrete structures. With the help of experimental design techniques and an effective software package, 12 adequate mathematical models have been developed and brought to the level of practical use. They allow to predict the reliability and bearing capacity of normal and oblique sections of specified structures for any combinations of concrete class, reinforcement class and reinforcement ratio. These models also allow to investigate both the direction of the change in bearing capacity and reliability index of prestressed reinforced concrete elements with the change of the above-mentioned factors, which is useful in solving some optimization problems at the design stage.
