Inverzní analýza spolehlivosti předpjatého mostu / Inverse reliability analysis of prestressed bridge

Lipowczan, Martin January 2018 (has links)
The proposed diploma thesis deals with the application of methodology and tools of inverse analysis for design of selected structural parameters using a fully probabilistic analysis to determine the level of its reliability. The method based on artificial neural networks is used to approximate the inverse function. The inverse analysis was carried out in two ways that differs in the method of obtaining reliability indicators. The structure analyzed in this work was an existing bridge. The year of construction is estimated approximately between the years 1955 to 1960. The bridge is located close to the Uherský Ostroh. It is a one-piece concrete slab made of MPD3 and MPD4 girders post-tensioned by tendons. Based on the 2006 and 2007 diagnostic surveys, laboratory tests, normative regulations and recommendations and, last but not least, sensitivity analyses, an inverse design of selected design parameters was performed for required limit states. Various load levels, different alternatives of design parameters and different neural network structures were studied.

Lesní vyhlídková věž v Beskydech / The Forest Viewtower in Beskydy

Kamrádová, Michaela January 2018 (has links)
Topic of this Master's Thesis is a design and a statical evalution of a load bearing structure of an observation tower in Beskydy mountains. Ground plan of this structure is in a shape of a nonagon with a non-roofed interior space. Height of the observation tower is 38,5 m, the shape of a ground plan doesn't change with a radius of a circumscribed circle of 12 m. The structure is designed from glued laminated timber, solid wood and steel. Columns bear horizontal beams and their stiffness is ensured by horizontal and inclined reinforcing beams. Main load bearing columns, upper and lower beams are designed from glued laminated timber GL24h. Upper beams and beams of a gallery are designed from glued laminated timber GL36h. Horizontal stiffener is designed from solid wood C24. Central column, inclined beams, stairway, water slide cantilevers, rod and central rod are designed from steel of a strength class S235. Cantilever for gallery is designed from steel of a strength class S355. Connections are designed from steel elements. Statical evaluation, technical report and construction drawing are included

Víceúčelový objekt v Pardubicích / The multipurpose building in Pardubice

Tunková, Eliška January 2019 (has links)
The topic of my diploma thesis is a design of a construction of a multipurpose building. The floor plan is of irregular shape with a maximal span of 35 metres. There are two buildings in shape of a hexagon, to which another building in shape of a half of a hexagon is connected. Part of the building is designed as a two-storey building and all parts are different in height. The hight of the designed building in its highest point is 13,5 metres. The load-bearing structure consists of glued laminated wood elements and raised wood with steel elements used as fasteners. The construction is designed alternatively from wood and steel. The static solution was made using the RFEM software.

Rekonstrukce visuté lávky v Kroměříži / Reconstruction of the cable suspended footbridge in Kroměříž

Liška, Jaroslav January 2020 (has links)
The Diploma thesis deals with the reconstruction design of a footbridge in the city of Kroměříž, Czech Republic. The footbridge would serve as safe transport for pedestrians over the Morava river. The main objective of the thesis is to conceive two or three reconstruction designs. The most suitable one will be opted for and elaborated in more detail. Eventually, strengthening of the bridge by means of additional prestressing using mono-strand post-tensioning systems is picked as the best solution of the planned reconstruction. The monostrand post-tensioning system is led under the deck, the cross section being outside. External cables are anchored in concrete blocks built around existing supports. Load-generated internal forces are calculated on a spatial bar model with non-linear first-order analysis. The calculation is executed using the finite element method in the midas Civil programme. The chosen reconstruction design is then assessed against load capacity limit states, and functionality. Also, the designed reconstruction is assed for dynamic effects. Results are compared with existing structure, and verified against the real-time tensometric measurement-obtained data. Dimensions, assessment of load-bearing structure, and structural details are all made according to valid Eurocodes.

Zastřešení objektu pro společenské účely / Roof structure of construction for social purposes

Bašista, Ján January 2013 (has links)
The work treats the static recalculation of an existing roof structure of a construction for social purposes and proposes two variants of the design of a new roof structure. The construction has a rectangular ground plan of 30 m x 47 m and the roof structure is placed on the load bearing circumference concrete walls. Except for the load constituted by the function of the construction and by the climatic area, an extra load of 2 tons suspended at any place of the structure is considered because of the special requirement of working and technological equipment. The variant no. 1 is designed from the steel S355. The variant no. 2 is designed as a combination of the wood GL24h and the aluminium EN-AW 5083. Both of the variants have 11 transverse load bearing girders. The purlins are perpendicular to the girders and are placed on them. Stiffness is secured by roof stiffeners.

Přepočet a variantní návrh ocelové střešní konstrukce zimního stadiónu v Jihlavě / Static verification and variant design of roof structure of winter sport stadium in Jihlava city

Bulíček, Radek January 2014 (has links)
The aim of the thesis is the assessment of steel structure roofing winter stadium in Jihlava city and design of the variant solution of load bearing steel structure of the roof. The ground plan dimensions are 60 x 84 m The current structure is composite of truss main girders with parabolic lower chords, and purlins . Axial distances of main girders are 12 m and are supported on concrete columns. The alternative proposed solution uses arched truss main girders and truss purlins. They are supported on existing concrete columns. All load bearing members of existing and new design structure – main girders, purlins, roof bracing - have been evaluated according to actual normative rules. It is evident that the static assessment of the existing structure is satisfied from viewpoint of ultimate and serviceability limit states. The static assessment of the new structure is satisfied from the viewpoint of both limit states.

Zogata, Pavel January 2015 (has links)
In my diploma thesis the proposal is developed as supporting steel structure sports hall with dimensions 45 x 54 m, a maximum height of 15.5 meters,for the area of Znojmo. In a static calculation are designed and assessed the main bearing structural components such as solid panel purlins, spatial lattice truss, bracing and solid panel columns, which together with the truss form create a crosslinks, column bases and anchoring, plus Tribune.The work includes the design documentation consisting of a layout drawing, drawing anchoring and drawing selected details.

Lečbych, Antonín January 2015 (has links)
The thesis contains the design and assessment of three-aisled steel building for small metal production. Supporting span of construction hall is 9, 18 and 9 m. In the middle wing is situated bridge crane with capacity of 2 tons. The estimated location of the object is Luhačovice. The initial design concept was specified by supervisor (as the idea of the investor/architect), for which was did static and structural solution and assembly details. For selected option was made a calculation of supporting structures and selected assembly details. The hall has a rectangular floor plan of 36x36m and ridge height is 9 m. The central wing is made of steel and side extensions are made of glued laminated timber.
