Application of FLAC in bearing capacity analyses of layered clays

Bhardwaj, Vivek 08 January 2007 (has links)
Understanding the bearing response of the footings on layered soils has always been a challenge for researchers. Due to the limitations of analytical and empirical solutions it had been difficult to understand the true bearing behavior. Some researchers have tried solving this problem by numerical analysis and have found some success. In this study the numerical analysis approach has been applied using a commercial tool FLAC (Fast Lagrangian Analysis of Continua) to study the bearing response of surface footings on layered clays. First, small deformation analyses were taken up to study the undrained bearing response of strip and circular footings resting on a horizontally layered strong over a soft clay foundation, and then over soft over strong clay foundation. In the end application of large strain mode of FLAC was explored to investigate the large deformation behavior of the strip footing resting on the surface of a strong over soft clay foundation. All models were run by applying velocity loading and a elastic-perfectly plastic Tresca yield criterion has been used. The results are compared with published Finite Element Method (FEM) results, and with analytical, empirical and semi-empirical solutions. It was found that bearing capacity results from the present small-strain FLAC analyses agree well with the FEM results. However, these results in most of the cases tend to differ (as much as 49% for certain layered clay foundations) from those predicted with analytical, empirical and semi-empirical solutions, mainly due to the assumptions made in these solutions. Since no such assumptions are made in the present FLAC analyses, the results and the methodology of this thesis can be applied to predict the bearing capacity of the practical problems. Application of the large-strain mode of FLAC to study the large deformation of shallow foundations has pointed out a limitation of FLAC in completing such analyses. However, it is observed from the early trends of these analyses that whereas the small deformation analysis may under estimate the ultimate bearing capacity for certain cases of layered foundations where the upper clay is moderately stiffer than the lower clay layer, it might also over predict the ultimate bearing capacity for other cases when the upper clay is very stiff in comparison to the lower clay layer.

Ocelová konstrukce tribuny / Steel construction of the tribune

Laža, Matěj January 2019 (has links)
The object of this thesis is to design and assess the roofing of concrete terraces on stadium Za Lužánkami in Brno. Rectangular plan of steel structure is 100x25 m. The main Girders are 5 m apart and are pin-supported. Girders are placed on concrete footings and supported by center columns. Roof cladding is connected with hot-rolled purlins. Two construction variants were designed and assessed. Variant A, where the main girders are made of welded beams (I shaped) and variant B, where the main girders are made of truss. Variant B was chosen as better option for this structure.

Šlézarová, Markéta January 2014 (has links)
Project documentation is about a university college and commercial facilities. It is a detached building, built in close proximity to the University of Economics in Olomouc. The building has five floors. The first floor is used for commercial purposes and another four floors for student accommodation. Roof is flat. The structural system consists of reinforced concrete columns and beams and bricks Ytong. Ceilings are reinforced concrete slabs. The roof is a single casing. The construction is based on reinforced concrete footings and the walls are passports.

Ekodukt na dálnici D1 / Ecoduct on Motorway D1

Matouš, Petr January 2014 (has links)
The master’s thesis focuses on suitable design of an ecoduct on the highway D1 near Jihlava. It includes a structural analysis of reinforced concrete strip footings and wooden beams in all phases of construction. The material of the main bearing system is glued laminated timber GL24h. An important part of three-jointed ecoduct wooden arched beams is well-chosen isolation.

Visioner och verkligheter : Kommunikationen om företagets strategi / Visions and realities : A case study of communication on corporate strategy

Johansson, Catrin January 2003 (has links)
The starting point for this study is the question of why organizational visions are often interpreted by employees as unintelligible and insignificant. The knowledge gap in this area makes the study of communication about vision and goals both urgent and interesting. Accordingly, the purpose is to advance knowledge on communication processes in organizations through description and analysis of communication about strategy, encompassing vision, strategic objectives and common values, in a company. A case study design was chosen and a longitudinal qualitative study was conducted in the company, from April 1998 to January 2000. A combination of methods were used, including participant observation, discourse analysis and interviews. Communication about the strategy followed a typical top-down model, starting on group level and ending on department level. In this process, Balanced Scorecard was used as a tool to communicate the strategy. It was concluded that visions formulated by top managers met different realities constructed by managers at lower levels in the company. Managers’ attitudes, knowledge and interpretations were important individual factors that influenced communication about the strategy. Employees did not have the same detailed knowledge of the strategy as the managers, nor were they given the same opportunities to obtain it. The discourse analysis reveals power structures, conflicts, individual attitudes and perspectives. The study thus results in a deep understanding of communication problems in the organization.

Fotombyte i teckenspråkstolkning : Erfarna tolkars koordineringsarbete på diskursnivå / Change of footing in sign language interpreting

Sterby, Pia January 2018 (has links)
Tolkens uppgift är att överföra budskapet från ett språk till ett annat på ett ekvivalent sätt. För att göra det måste tolken koordinera samtalet. Tolkens koordineringsarbete och tolkens förmåga att navigera mellan de olika modaliteterna där talad svenska och teckenspråk förekommer är avgörande för en funktionell tolkning. Den här uppsatsen har fokuserat på sekvenser där tolken i sitt koordineringsarbete ägnar sig åt att förflytta sig mellan olika samtalsramar. Detta kallas för change of footing (sv. tolkens fotombyte). I det filminspelade materialet har fyra kategorier av change of footing påträffats. Den första handlar om den förändrade deltagarstatusen som uppstår när tolken från väntläge går in i rollspelet. Den andra kategorin handlar om tolkens självpresentation som för teckenspråkstolkar innebär att hantera en oväntad direkt fråga. Den tredje kategorin handlar om när tolken själv tar initiativ till omfrågning för att försäkra sig om innehållet och/eller innebörden av det som yttrats. Den fjärde och sista kategorin handlar om den förändrade deltagarstatusen som tolken förflyttar sig till när rollspelet avslutas. Just avrundning av pågående samtal är ofta en process som kan pågå i flera minuter där både de primära parterna och tolken signalerar detta på en rad olika sätt. / The task of an interpreter is to convey the message from one language to another in an equivalent way. In order to do that the interpreter needs to coordinate the interaction. The coordination and the ability to navigate between the different modalities that spoken Swedish and Swedish sign language are part of is decisive to achieve a functional interpretation. This thesis has focused on sequences where the interpreter in her work moves between different interactional frames. This movement is called change of footing. In the film-recorded data, four different categories of change of footing have been found. The first one concerns the changes in participation status, which occur when the interpreter moves from a “waiting position” into the roleplay. The second category is about the interpreters’ self-presentation, which for sign language interpreters is an unexpected direct question to handle. The third category deals with an interpreter-initiated repair in order to make sure the meaning of an utterance or a word is correctly understood. The fourth and final category is about the changed participation status when the interpreter moves out of ongoing roleplay as it ends. Finishing an ongoing interaction is often a process that might go on for several minutes and that is signalled by both the primary parties and the interpreter in a number of different ways.
