1. Advanced numerical methods for the design and assessment of structures and infrastructure

   The aim of this thesis is the advancement of current state-of-the-art in numerical methods, including simulation techniques, to increase efficiency in the assessment of structures and infrastructure. Results of this thesis will serve as a theoretical basis for the revision of current analytical approaches.

   Tutor: Podroužek Jan, doc. Dr.techn. Ing.

2. Aspects of internal structure influence on mechanical fracture properties of selected composites

   This thesis topic focuses on a complex analysis of the influence of the internal structure of selected composites, specifically regarding their mechanical fracture properties. In order to achieve this aims, the thesis will contain a numerical analysis of particle models together with implementation on specific small-grain size composites (for example technical refractory ceramics). There will be cooperation with the Institute of Building Testing and private sector, and support of these supervisor-specialists: 1) doc. Ing. Petr Frantík, Ph.D. and 2) doc. Ing. Pavel Schmid, Ph.D.

   Tutor: Keršner Zbyněk, prof. Ing., CSc.

3. Design optimization of concrete structures

   Definition of optimisation model of a structure for: 1. design of a member, 2. strengthening of existing member, 3. design and strengthening of a structure. Calculation variant: stochastic, deterministic (according to the application class of the tasks), type of the restraining conditions, classes the target functions.

4. Fatigue and fracture of advanced materials for civil engineering structures

   Knowledge about behaviour of building materials based structures through the effective application of methods of complex determining of physical-mechanical and performance qualities to describe fatigue and fracture-mechanical characteristics/properties.

   Tutor: Seitl Stanislav, doc. Ing., Ph.D.

5. Physico-mechanical and durability characteristics of construction concrete elements with alternative adition of fibres with waste sources.

   Both organic and anorganic fibres from waste raw materials can be used purposefully in construction fibre concretes with extracted aggregate and concrete recyclate. The comparison of physical-mechanical and durability characteristics of fibre concretes with and without loading can contribute to estimating lifetime and ductility behaviour of fibre concretes of different formulations.

   Tutor: Stehlík Michal, doc. Ing., Ph.D.

6. Resistance of loaded structures of construction fibre concretes to the action of environment and chemical substances.

   The main goal of the dissertation is to analyze permeability and diffussion characteristics of fibre concretes with selected types and doses of fibres. The testing will be carried out on both loaded and unloaded samples with cracks made by bend loadind. The main output will be the proposal of formulations and estimation of durability of different types of fibre concretes especially loaded to achieve higher durability of reinforced concrete constructions.

1. round (podání přihlášek od 15.06.2018 do 31.07.2018)

1. Inspection based probabilistic modeling of fatigue crack progression

   The aim is to develop the methodology of quantification of time-dependent analysis of the failure probability of elements of bearing steel structures. Theoretically based numerical instruments will be developed for the behaviour simulation of elements of these structures which are prone to formation of fatigue failure. The efficient stochastic approaches, enabling to study the influences of parameters under uncertainties on model responses of steel structures in time will be studied.

   Tutor: Kala Zdeněk, prof. Ing., Ph.D.

2. Physico-mechanical and durability characteristics of construction concrete elements with alternative adition of glass recyclate of photovoltaic panels

   The glass surface photovoltaic panels have a lifespan of approximately twenty years. Recycled glass in a different factions is created by crushing this area. One of the potential application is the substitution of the coarse aggregate of concrete by glass recyclate. The results of a number of mechanical and physico-chemical tests without and after application of load shall decide on the use of concretes with the glass recyclate and shall help with the assessment of efficiency of production.

   Tutor: Stehlík Michal, doc. Ing., Ph.D.

3. Sensitivity analysis of reliability of steel structures

   The reliability and limit states of bearing steel structures will be studied using stochastic computing models focused on sensitivity, statistical and probability analysis. Stochastic models will be created with the knowledge of numerical simulation methods and FEM nonlinear models, including knowledge of structural mechanics, theory of elasticity and plasticity, and other related disciplines necessary for stochastic modeling and computing.
