Experimentelle und numerische Untersuchung des dynamischen Verhaltens von Stahlbetontragwerken unter Berücksichtigung stochastischer Eigenschaften
The relation between damage and the changing of dynamic and static properties of R/C structures is investigated. On the one side static experiments in relation with dynamic experiments of R/C structures (plates and beams) are performed. On the other side a nonlinear Stochastic Finite Element Model is developed. The model considers stochastic material and strength properties by spatial correlated random fields. So a random crack evolution for the R/C beams are simulated. As Monte Carlo Method Latin Hypercube Sampling is used to calculate a lot of samples and so various "live histories" of the structure. The evaluation of structure response for the load history indicates the influence of stochastic properties on the damage evolution. The work gives a contribution to the assessment and the use of dynamic investigation methods in the future in civil engineering.
