Visutá lávka pro pěší přes řeku / Suspension footbridge across the river

Chumová, Petra January 2014 (has links)
The subject of the thesis is to design a suspension footbridge over a river basin. Three different studies were created for the assigned problem. The suspension footbridge was chosen for the thorough elaboration. The most important part of the thesis is the static solution of the supporting structure. The structure model for calculation of impacts of selected strains including the impact of the footbridge construction was created in computational software Ansys. Assessment and dimensioning was carried out using manual calculation according the principles of limit states and applicable standards.

Lávka přes řeku Úpu v Trutnově / Footbridge over Úpa river in Trutnov

Výborný, Martin January 2015 (has links)
The goal of this thesis was to design a steel structure of a footbridge for pedestrians and cyclists over the river Úpa in Trutnov spanning 20m. Also, it was calculated with a crossing of 3,5t vehicle. Preliminary design was carried for two variants. Variant B is truss structure, structure of Variant A is carried by prestressed cable and is further developed. Main structural beams of variant A are designed to be a shape of parabole with the middle beam connected by arbitrary profiled vertical beams to supporting prestressed high yield cable. For the design of structure, SLS was the main factor so elastic check is performed for ULS.

Electromagnetic damping for control of vibration in civil structures

Ao, Wai Kei January 2017 (has links)
This thesis investigates an alternative solution to deal with the civil structure vibration. Non-contact electromagnetic or Eddy current damping is selected as a score of vibration suppression. Electromagnetic damping relies on the interaction between a permanent magnet and conductor. An electromagnetic damper (EMD) is applied both to a laboratory footbridge structure and 6-storey model-scale aluminium moment resisting frame (AMRF). In this first study the EMD is connected in series with an electronic shunt circuit to construct an electromagnetic shunt damper (EMSD). A robust optimisation method is applied to develop the corresponding optimal design formula of the EMSD. The principle of an EMSD is to convert mechanical energy to electrical energy. Hence, the induced electromotive force (emf) is generated by electromagnetic induction. This emf induces an amount of shunt damping, which is fedback to the structure to achieve vibration suppression. It was found that when the impedance was applied, the shunt damping feature was of a similar nature to viscous dampers. In contrast, when an RLC (resistance-inductance-capacitance) circuit is connected, the shunt damping is analogous to a tuned mass damper. A second form of EMD is Eddy current damper (ECD), which relies on a geometrical arrangement of permanent magnets and conductors to produce damping forces. The vertical and horizontal orientation of the magnet, unidirectional and alternative pole projection and moving different direction of the conductor are investigated. A theoretical study involving the infinite boundary and finite boundary (the method of images current) is carried out to obtain an analytical calculation of the damping force. On the basis of this analysis, one type of ECD prototype was physically built. A performance test was carried out to determine the damping characteristics of the ECD, which agreed with the results of the numerical analysis. In addition, the ECD was applied to control the dynamics of the 6-storey AMRF. It was found that, the ECD can effectively increase system damping and have a satisfactory control effect.

Computational model for morality and emotions in EmoBN / Beräkningsmodell för moral och emotioner i EmoBN

Fröcklin, Henry January 2014 (has links)
This master thesis presents an approach on how to design moral behaviour in a scenario with een. een is an iteration of emobn which is based on bn, an action selection system with activation dynamics among modules, goal oriented and capable of prediction and planing. The design is based on current research from prominent psychologist like Haidt and uses Mikhial’s umg framework for causal and intentional validation. Also Roseman’s appraisal model and Haidt’s mft is used for determining moral emotions in a moral context. The design is tested against empirical results from philosophical experiment know as the trol- ley problem, a well known moral dilemma.

Aquapark Brno / Water park Brno

Smička, Matěj January 2018 (has links)
The topic of the diploma thesis is the design of the Luzanky sport complex in Brno. The main objective of the diploma project was to create a new modern sport recreation area which will be situated next to the existing swimming pool. The main function is an aquapark with indoor and outdoor pools, which will fulfil all needs of visitors. There are few other functions added, such as café, smaller fitness and massages. Absolutely main objective is to connect the existing pool with the pools of the Aquapark - so the visitors could be using all indoor swimming areas. There are also parking spots designed within this project - nearby is a parking garage connected by footbridge leading from the existing swimming pool alongside the Aquapark building. This footbridge is intended for people who come to Brno to the Aquapark - for families with children that is - therefore it ensures safe and uninterrupted crossing from the garage to the new Aquapark complex. This complex will meet the requirements and current expectations of the visitors in the area. It will also increase the attractiveness of the entire territory.

Aquapark Brno / Water park Brno

Liznová, Veronika January 2018 (has links)
The topic of the diploma thesis is the solution of the Lužánky sport complex in Brno. The aim of the diploma project is to create a new modern sport recreation area which will be situated next to the existing swimming pool. The main object is an aquapark with indoor and outdoor pools. In area of the aquapark are other premises like wellness, fitness cen-ter, café and other small businesses. Proposed object should be connected to the exis-ting pool with a 50-meter track. Visitors could go from one place to the other without exiting the complex. Also included is the increase of indoor and outdoor parking. Around the complex a footbridge had been designed to connect all the sports facilities. The foot-bridge is intended for pedestrians and cyclists and is designed to avoid blocking car traffic. Main entrance to the aquapark is on the same level as the footbridge, on the 2nd floor. Visitors can go to the footbridge by pedestrian ramp, stairs or lifts. This complex will meet the requirements and current expectations of the visitors in the area. It will also increase the attractiveness of the entire territory.

Lávka pro pěší přes řeku / Footbridge across river

Klíč, Radim January 2019 (has links)
The diploma thesis deals with a design of a steel loadbearing structure of a footbridge over a river. The footbridge is located in Svitavy and is designed for span length of 60 meters. The construction is preliminarily designed in two variants. A part of the thesis is also a comparison of both variants. The chosen variant has been elaborated in detail. It is an arched construction with a semi-through bridge deck. The main loadbearing structure consists of a pair of arches that support the steel-concrete bridge deck by means of rods in tension. The main loadbearing arches are inclined from the vertical plane towards the bridge axis and are fixed at the ends. All steel parts are designed from S355 steel, except for the rods that are designed from S460 steel. The bridge deck is designed from C 35/45 concrete. The spatial rigidity of the structure in the transverse direction is achieved by means of arc sway bracings.

Lávka přes nádraží / Pedestrian Footbridge over Railway Station

Hurych, Marek January 2020 (has links)
The diploma thesis deals with design of loadbearing stell structure of a footbridge across the railway station. Footbridge is situated in the city centre of Brno with total length of 135 meters. For comparison, three bridging variants are predesigned and a varints comparison is made. The selected option was developed in greater detail. It is an arched structure with a semithrough bridge deck and adjacent span with support of oblique column. The main loadbearing structure consists of a pair of pin-supported arches inclited to each other at an angle of 11°. Arches support beams with susperder, the beams are conected by ortotropic steel deck. All load-bearing elements are designed from S355 stell. Spatial rigidity of the structure is ensured by tilting of the arches and by truss bracing at the top of the arch in combination with rigid struts of arch. Spatial rigidity of the superted deck is ensured by ortotropic steel deck.
