Design of the RC slabs of the flat house
Reinoha, David ; Požár, Michal (referee) ; Klusáček, Ladislav (advisor)
The topic of the bachelor thesis is a new two-storey production building with an administrative part on the second floor and a production space on the ground floor The bachelor thesis deals with the static assessment of selected main bearing elements of the whole building in details for building permit. The main vertical supporting structure here is peripheral ceramic masonry, which is bounded by iron-concrete wreaths at the level of each of the two floors. The building is roofed with wooden nailed roof trusses placed on an in to wall-anchored wooden beam. The main supporting horizontal structure forming the ceiling between the first and second above-ground floors is made up of prefabricated Spiroll ceiling panels, which are placed on the stiffening wreath 1NP. The foundation structures are made of a monolithic concrete waist and consequently of a prefabricated lost formwork.

Strengthening of roof girders in production hall
Wawreczka, Karel ; Strnad, Jiří (referee) ; Klusáček, Ladislav (advisor)
The aim of my bachelor’s thesis is strengthening of girder roof construction in a production hall. The roof girders were designed 18 years ago in accordance with the Czech standards valid at that time. All the girders are now recalculated according to valid European norms. It is suggested to use prestressed cables guided along the girder construction. Because of the lack of space around the front of girders, it is designed to use prestressing from in the middle. In order to design the cable geometry and the biasing force, it was crucial to take into account shear resistance as well as constraining compressive stress in the concrete. Calculation of the effects of load is carried out by Scia Engineer 2015 computer software whereas Excel has been used for all the other calculations.

Prestressed girder bridge
Páteček, Tomáš ; Klusáček, Ladislav (referee) ; Panáček, Josef (advisor)
The thesis deals with the design of a new bridge construction at the place of an existing bridge on the road II/39 between the villages of Dobrkovice and Kájov over the river Polečnice. Three studies were developed as a solution. The chosen variant contains the construction of a prestressed girder bridge, simply supported, with a length of bridging 27,464 m. The category of the transferred road is S9,5, a body of transferred road is on both sides of the bridge in the embankment.

Reconstruction of the road bridge
Laczko, Zoltán ; Krejčík, Vladimír (referee) ; Klusáček, Ladislav (advisor)
The subject of this thesis is to design a new slab structure instead of the steel concrete slab. The structure of the new load bearing structure is post-stressed cast-in-situ slab with continuous slab structure consisting of three spans. The slab is pre-stressed by monostrands. The load bearing structure is evaluated for first and second limit state too. The construction is modeled in software named Scia Engineer 2011.

Design of the single span bridge in Vražné
Juřenčáková, Jana ; Svoboda, Adam (referee) ; Klusáček, Ladislav (advisor)
The subject of bachelor thesis is a design of single span bridge in Vražné. Within the scope of thesis there are three studies of bridge. Cast-in-place concrete slab super structure was found appropriate and further calculations were assessed. Length of span is 15,00 m. Internal forces were provided by SCIA Engineer and checked with manual calculation. The supporting structure was assessed for the ultimate limit state and serviceability limit state. Calculations were made according to valid standards and regulations.

Design of the floor structure in block of flats
Rejnart, Michal ; Chalabala, Jiří (referee) ; Klusáček, Ladislav (advisor)
This bachelor thesis deals with design of floor structure of residental building. Load-bearing structure is checked for the Ultimate Limit State and Service Limit State. This structure is designed like a two way slab on linear support. The report contains detailed description of structural system with used building materials. There are terms for technological process of designed structure in this section. The structural design report contains assessment process of designed structure and scored results.

Strengthening of vaulted structures by prestressing
Požár, Michal ; Solař,, Jaroslav (referee) ; Drahorád,, Michal (referee) ; Klusáček, Ladislav (advisor)
The topic of this Ph.D. theis is repairing and strengthening of historical wagon vaults (barrel vaults, tunnel vaults) using post tensioning with tendons (monostrands) in longitudinal direction. The vaults should be without an edge, that´s mean the baroque vaults are well appropriate for this method. The pointed barrel vault should be problematic. The stabilization is for a wagon vault created by semicircle or segment part of a circle as well as an elliptic shape. The study has been made for vault with a width of 1 m and for the prestressing force has been used one tendon only. Of course, this method could be apply for normal constructions with a width of many meters. In this case, more tendons should be use with a suitable spacing. The goal of this work was to monitor an experiment model of an wagon vault and a real strengthened baroque vault of a church in Švábenice. During the monitor time, the static Analysis has been made. For these analysis appropriate finite elements in Ansys program has been use. The results of this work is to amplify the knowledge of the real behaviour of strengthened vaults, which could be use like instruction for the civil engineers. Further the public information guide to build an appropriate model of an Vault with an interaction with post-tensioning tendons.

Design of the office structure
Totková, Lucie ; Pinkas, Karel (referee) ; Klusáček, Ladislav (advisor)
This thesis deals with the design and assessment of the cooling reinforced concrete ceiling by EC2: Design of Concrete Structures. The introductory part is focused on selected type cooling ceiling system and its detailed description. The important part is dedicated to influence of water temperature on reinforced concrete ceiling structure. In this thesis is included calculation of internal forces, calculation of maximal deflection of the slab and its assessment of the puncture. This task is analysed using the software SCIA Engineer and ANSYS.

Design of strengthening of the concrete structure from 1928
Bažantová, Lenka ; Pinkas, Karel (referee) ; Klusáček, Ladislav (advisor)
The bachelor’s thesis is focused on assessment of the existing construction four-storey building. The supporting system consists of cast-in-place concrete frame. The aim of this work is to assess the support structure for the expected loading of the resulting change in use of buildings for residential or commercial purposes. The subjects of assesment are columns, beams, girders and floor slab. In another part of work is suggested by reinforcement of non-conforming elements. The work includes the development of stroctural analysis and reinforcement drawings of reconstructed elements.
