Numerical design approaches of textile reinforced concrete strengthening under consideration of imprecise probability
The paper focuses on numerical approaches valuable in the design of strengthening layers made of textile reinforced concrete (TRC) applied on surfaces of RC structures. The presented methods aim at the design of structures that are components of significant buildings, e.g. power stations, historic valuable buildings and life lines. The generally existing uncertainty of material and geometry parameters of the RC structures and the TRC layers is modelled by imprecise probability. Reliability, lifetime and robustness are assessed by means of generalised uncertainty measures and considered as design objectives or constraints. Three computational methods are developed for the computation of preferential designs under consideration of imprecise probability. The methods are applied for the design of a porch roof strengthening comparing the robustness of different variants and for the reliability-based design of a T-beam strengthening.
