Project description:The project introduces the solution of problems of the stochastic evaluation of safety and reliability of bearing reinforced-concrete structures considering the soil-structure interaction, extremal load and degradation of material characteristics. From the point of view of the probability approach, the building structures are analyzed during the phases of their design, operation and reconstruction, until they reach their age of the designed life span. The stochastic analysis of structure damages is built up on the basis of nonlinear analysis of structures for assumed average values of material characteristics and load. The analysis of the safety or the reliability of the structure comes from the same level of the probability of variable material characteristics of structure elements, load impact and probability of damage of structure as a complex unit. The probability analysis of the structure collapse loaded by extremae load comes from the solution of nonlinear behavior of structure as a complex unit, step by step.The probability of the damage of structure as a complex unit can be solved using the simulation of possible variation form the average values of material characteristics and the load. Nonlinear solution is specified to problem of the analysis of the walls and frame-wall coupled systems considering the theory of smeared cracks, rotated cracks, layered approximation, degradation of concrete strength by Collins and Červenka, shear modulus by Kolmar and the plasticity condition by Kupfer, Owen and Chen.
