【 摘 要 】

Building structures are continuously subjected to loads, environmental and climate influences. The effects are particularly noticeable over time in a case of historic buildings. The effects of the interaction processes are changes in a technical parameter. Structures require renovation, repairs and strengthening preceded by identification of forces and stresses in members. Apart from traditional technologies, modern materials and adhesive bonds with high strengths are used in renovation works. The paper presents an effective way of modelling and assessing the state of stresses in structures and degraded or strengthened elements using computer analyses. The developed model is based on the finite element method, significantly reducing the number of unknowns. The model can be used to identify the state of stress and strains in the design of strengthening, repairs and renovations of structures.
