Laboratory Applications Designed for Support and Verification of Numerical Analyses in Civil Engineering

Popis výsledku v původním jazyce

The objective of this doctoral thesis is to develop various laboratory applications which are based on digital image processing and analysis, fuzzy logic, genetic algorithms, and electronics. Generally, the concept stems from the need for acceleration and automation of processes which are either slow or impossible to perform manually. It is a case of, for instance, visual inspection during experiments. The accuracy of numerical analyses is usually highly dependent on input data. Hence, the area of interest is related to verification of results of numerical analyses, such as displacement, temperature, and cracks. Digital image analysis is employed as a non-contact measuring technique of response of structures to both static and dynamic loading. Localization and description of cracks of concrete structures is performed by a fuzzy logic approach. The proposed method is based on conversion of the targeted problem into a human perception issue. The fuzzy logic is also utilized in connection with an open-source electronic prototyping platform. A genetic algorithm is developed for effective interconnection between experiments and numerical analyses related to hydration of concrete. A self-designed device for testing effects of temperature on hydrating concrete specimens is also provided. The emphasis is put on usage of reasonably priced equipment instead of expensive high-tech devices while maintaining an acceptable accuracy. Due to this reason, the proposed methods are widely applicable.
