Array of Stell Aggregate Bins
Krchnák, Martin ; Bajer, Miroslav (referee) ; Brosch, Petr (advisor)
This diploma thesis describes the design and assessment of steel structural design of the steel aggregate bins including roofing. The construction has a ground plan of about 33 x 9 m and it is divided into 8 cells bins. Main material is steel, grade S355 and S235. There is developed a static analysis of the main load-bearing parts of the structure, including joints and selected details.

Steel structure of swimming pool roof
Krchnák, Martin ; Barnat, Jan (referee) ; Štrba, Michal (advisor)
This bachelor thesis describes the design and assessment of steel structure of the swimming pool roof. The supporting structure of hall has 40.00 meters span, 50.00 m length and 10.53 m height. Main construction material is steel, grade S355 and S235. There were compared 2 possible variants of the roofing, and one of them was calculated in detail. There is developed a static analysis of the main load-bearing parts of the structure, including joints and selected details. The supporting structure of roofing consists of the polygonal wrapped lattice structure made of steel circular in the transverse direction.

Návrh konstrukce suchého doku pod svislým zatížením
Zetková, Simona ; Polák, Barnabás (referee) ; Uhrin, Michal (advisor)
The aim of this thesis is to undertake simplified design and assessment of cofferdam under vertical surcharge in the form of virtual project. Cofferdam constructed on the sea shore must be able to withstand all loads to enable construction of cut and cover tunnel. As a part of the design it is required to assess ground conditions and it is necessary to review feasibility of the structure on the sea. The construction will be described in construction phases and graphically demonstrated in construction sequence drawing. Because the structure is designed for life time of five years, temperature load on struts is studied in the thesis and further considered in structural analysis. Furthermore, it is required to compare analytical models from GEO5 and PLAXIS. Horizontal frame is analysed separately in Scia Engineer. Structural members – cofferdam wall, waler beam and strut are checked in this thesis. For the design of the cofferdam wall second order theory is considered. All mentioned requirements were accomplished with help of corresponding Eurocodes, books and technical advice. Results of this work are feasible and it was possible to design all members to enable construction of the cut and cover tunnel. The phasing was designed such that deformation of the cofferdam is minimalized and use of machinery is limited to machines on temporary platforms. Comparison of two different analytical models showed that different soil modelling has great effect on internal forces, even though the shape of the bending curve is very similar, values obtained from PLAXIS software are much higher. Assessment of the structural members is done according to Eurocode 3, and horizontal frame is checked also against disproportionate collapse.
