On the project
Předmětem projektu je vývoj numerických metod a algoritmů pro efektivní syntézu pokročilých postupů pro modelování spolehlivosti mostů a infrastruktury. Již existující softwarové prostředky pro nelineární výpočtovou analýzu betonových mostů a konstrukcí budou rozšířeny o softwarové moduly z oblasti pokročilých metod výpočtové mechaniky kontinua, metod soft computing, dynamické analýzy, spolehlivosti a degradace.
Description in EnglishThe aim of the project is to develop a new bridge/infrastructure assessment software system that will allow to assess performance, reliability and damage based on health monitoring, data-driven approaches and system identification on the level of cracks propagation and hence considerably improve prognosis of bridges reliability. We will deliver an integrated software system both as a product and as a consulting service. System will be based on computational nonlinear modelling of structures and will include extending modulus for: sensitivity analysis, fractal-based damage assessment procedure based on cracks pattern evaluation in concrete structures, surrogate modelling based on polynomial chaos expansion, dynamic damage identification, reliability and degradation modelling.
KeywordsNelineární analýza; spolehlivost; soft computing; identifikace poškození; degradace; beton; mosty; infrastruktura
