Experimental Verification of Printed Concrete Shell Structures
Tomečka, Petr ; Stráský, Jiří
The article presents the printing technology and material used in the research. Focusing specifically on shell structures. The following section details, the application concept for bridge piers and the derived specimens for experimental verification. The testing procedure and a description of the measuring equipment is presented. Finally, an introduction to computational analyses is provided.

Pedestrian bridge across the river Nitra
Tomečka, Petr ; Kaláb,, Pavel (referee) ; Nečas, Radim (advisor)
The subject matter of this master thesis is to design pedestrian bridge across the river Nitra in a city Nitra. Out of three possible solutions arch bridge was considered to be the most optimal system for given situation and it was analysed in detail. The design and assessment of load-bearing structure was evaluated acording to valid standarts. The main goal was to comply with ultimate and serviceability limit state. Global calculation model was created in ANSYS Mechanical APDL 21 R2. Model of the slab of the deck in the cross direction was performer using SCIA Engineer 19.1. Load capacity of some cross sections was verified manually and some using computer software IDEA Statica 21.0. This thesis is extended with drawings of sequence of construction, detailed drawings of the bridge and visualizations.

Design of a one-span slab bridge
Sobková, Sára ; Tomečka, Petr (referee) ; Nečas, Radim (advisor)
Subject of bachelor thesis is reconstruction of railway bridge on the route from Český Těšín to Ostrava-Svinov in km 6,482. The structure is located in the extraregion. There are two rail routes on the bridge and local road under the bridge. One-span slab reinforced consrete bridge is designed and placed on the rail as a replacement for bearings. the length of the bridge is 6 m. The sffects ot the load are calculated in the programe AxisVM and static calculation are made in the program Mathcad. Bending and shear steel is designed. Serviceability limit state is verified. Also the resistance of steel concrete to cyclic loading is calculated. Steel of the abuntment is designed to reduce the appearence of cracks above the working joint due to ahrinkage. Dynamic coefficient is verified.

The design of bridge structure in Žďár nad Orlicí
Tomečka, Petr ; Bobek, Lukáš (referee) ; Klusáček, Ladislav (advisor)
The aim of Bachelor thesis is to design reconstruction of the bridge and assess of new load-bearing structure. From three possible solutions monolithic slab was chosen as best one. The design and assessment of load-bearing structure have been carried out to valid standards. The goal was to comply ultimate and serviceability limit state. The load effects calculations has been performed manually and by using software Scia Engineer 19.1. The thesis is supplemented by drawings and visualizations.

Design of a slab bridge
Stehlík, Ondrej ; Tomečka, Petr (referee) ; Nečas, Radim (advisor)
That aim of this bachelor's thesis is to present a design of a single-span slab bridge. The main framework is constituted of a post-tensioned concrete slab. The bridge carries a road of category S7.5 over the river between two intersections. Overall, three variants have been created. From these variations, a design using a slab with a flat underside was chosen. Construction analysis was performed in Scia Engineer 21.1. The design and review were performed manually.
