Pełny tekst źródłaOs projetos de capacidade de suporte de estacas estão baseados em dados de ensaio de campo de maneira direta ou indireta. Devido a sua praticidade, os métodos empíricos são amplamente utilizados. No Brasil os métodos de Decourt e Quaresma (1978, 1982) e de Aoki e Velloso (1975) se destacam. Este trabalho procura avaliar o uso de dados de SPT e CPT para estimativa de parâmetros geotécnicos necessários na previsão de capacidade de suporte de estacas através de métodos teóricos. São apresentadas e avaliadas formulações empíricas de estimativa de parâmetros para materiais granulares e materiais argilosos. Outro elemento importante na previsão da capacidade de suporte é o estado de tensões atuante em torno da estaca que é analisado através de considerações a respeito do coeficiente de empuxo. Finalmente, são mostrados alguns resultados de provas de carga para a análise da seleção de parâmetros e do estado de tensões, além de uma avaliação dos métodos empíricos de previsão de capacidade de suporte.
The main objective of this thesis is to discuss the applicability of in-situ tests like the Standard Penetration Test (SPT) and the Cone Penetration Test (CPT) to determine directly the design parameters to predict the bearing capacity of pile foundations. In case it will be considered the use of empirical correlation to indicate the mechanical properties of the soil in terms of shear resistance, and the application of these values directly in the classic formulation based on the theory of equilibrium limit to evaluate distinctly the shaft and the base resistance of piles. Adaptations of these values will be proceeded considering aspects related with the non-linear behavior of the soil; the mechanism of load transfer and the influence of the constructive aspects.The results obtained through this new methodology will be compared with experimental results, obtained from static and dynamic load tests and also with other empiric procedures that use the results obtained from in-situ tests to evaluate directly the bearing capacity of deep foundations.

As fundações dos elementos de apoio de uma linha aérea de transmissão de energia elétrica situam-se ao longo de extensos traçados, onde diferentes condições de apoio para as estruturas são encontradas em razão da variação natural dos horizontes. Tal configuração pode levar alternativamente a se programarem estudos e sondagens especiais em cada local de suporte, fazendo crescer os custos e prazos de projeto, ou ao contrário, reduzindo drasticamente a investigação, com prejuízos evidentes ao planejamento, execução e economia da obra de implantação da linha de transmissão. Dessa maneira, são organizados e propostos procedimentos para avaliação do terreno segundo as suas orografia, hidrografia, geologia e pedologia e do ambiente atmosférico local, cujas manifestações são capazes de impor severas solicitações às torres e, indiretamente, às fundações. É eleita a região da bacia do rio da Prata para constituir o grande cenário do estudo, quer pela abundância de dados e informações disponíveis sobre linhas de transmissão já em carga, ou ainda em construção, nessa região. Assim sendo, desenvolve-se uma metodização para orientar o estudo dessas fundações, considerando o conjunto torre x terreno x fundação e buscando soluções técnicas convenientes e economicamente aceitáveis, atendendo assim ao binário desempenho-custo. Para as torres são considerados os modelos auto-suportados e estaiados, o terreno é variado entre algumas categorias identificadas na região e as fundações são representadas pelas superficiais, em sapatas, e pelas profundas do tipo tubulão. Buscando, ainda, auxiliar no aprimoramento dos projetos de fundações para suportes de linhas de transmissão, é desenvolvido um estudo de confiabilidade estrutural tendo como modelo algumas das fundações pré-selecionadas para a metodização primariamente desenvolvida. São determinadas as probabilidades de falha dessas fundações através do programa FERUM e, a partir do levantamento dos prejuízos financeiros causados pela falha desses elementos, determina-se o risco de falha. Por último, é desenvolvido um estudo paramétrico para avaliar a influência do projeto de fundação, do tipo de solo e da velocidade de vento sobre a probabilidade de falha.
The transmission line tower foundations are executed following extensive paths, where different structural foundation conditions are found, in reason of natural horizontal ground layer variations. Then, one may alternatively to schedule and to execute special and specific studies or, conversely, to substantially reduce the geothecnical investigation, with sensible economical loses in the transmission line design and behavior. In such way, a methodology is proposed to evaluate conveniently the site according to its geology, orography , hydrography and pedology as well to related atmospheric local manifestations, able to submit severe mechanical solicitations to the towers and their foundations. In this way, one proposes a methodology to govern the study of these foundations, considering the tower x site x foundation relations and searching for convenient technical and acceptable economical solutions. Guyed and self-supported models are considered for towers, and the foundations are represented by footings, as the superficial type, and piers, as the deep type. The rio do Prata basin is chosen to constitute the large scenery of the study, because its abundant available data concerned to already operational transmission lines, or still under design and construction ones. Moreover, seeking the improvement of the tower foundation design a study based on structural reliability is developed considering some foundation models selected as mentioned above. Foundation failure probabilities are determined by the FERUM computational program and the risk of failure is obtained from economical damages caused by foundation failures. In the last, a parametric study is developed to evaluate how does the failure probability behave according to variations in the foundation soil, wind velocity and footing dimensions and depth.

Pełny tekst źródłaFoundation is one of the most important part of construction. Is it a connection between the a structure and a ground that support it. Even in ancient times it was known that most carefully designed structure will fail if the foundationi do not give sufficient support. Thus the proper design of foundation and selection of adequate kind of foundation allow to avoid later constructional problems. Early foundation design was based mostly in intuition and common sense. Builders developed rules for sizing and constructing foundation through trial-and-error method.

Universities of Technology have traditionally prepared students for the world of work and their close ties with industry directly impact on vocational curriculum, which has to impart subject knowledge and specialized knowledge valued by industry, whilst simultaneously encouraging the acquisition of vocational identity. This study of a Design Foundation Course’s curriculum is located at a University of Technology which is currently undergoing a process of re-curriculation, which has initiated a process of examining subject knowledge and its structuring in various course’s curricula. In the light of these developments, an examination of the nature of design knowledge and the role of the foundation curriculum in the transfer of core disciplinary knowledge to underprepared students appeared both timely and necessary.

Pełny tekst źródłaIn this thesis we formulate and analyze a class of fundamental task scheduling problems arising from a variety of emerging computing and communication systems: tasks are partitioned into groups; those in a group can be batched and executed simultaneously; the goal faced by the scheduler is to design scheduling algorithms maximizing the overall system utility. Under the above generic umbrella, we investigate different classes of batching task scheduling problems, establishing the corresponding theoretical framework, designing both offline and online scheduling algorithms, and illustrating their application in scheduling communication and computing tasks. We start by the baseline scenario of batching task scheduling. There is a set of tasks to be executed on a number of machines. Some tasks can be executed simultaneously on a single machine, while others require exclusive use of an entire machine. We seek an optimal scheduling policy to maximize the overall system utility. We develop an algorithmic framework for the above scheduling problem in the generic form that can achieve 1/2-optimality, outperforming the best known result. The core technicality in our design is an adapted LP relaxation mechanism and a rounding and coloring approach that turns the solution of the LP relaxation to a 1/2-optimal feasible scheduling policy. We then demonstrate the application of our algorithmic framework to solve the generalized proportional broadcast problem by developing a deterministic approximation algorithm outputting an l_min/(2(l_min+1))-optimal scheduling policy, while there exist only randomized algorithms in the literature. We then formulate and analyze a fundamental downlink transmission scheduling problem in wireless communication systems, composed of a base station and a set of users, each requesting a packet to be served within a time window. Some packets are requested by several users and can be served simultaneously due to the broadcast nature of the wireless medium. Compared to the baseline model, there are two particularities. First, each request can be served by a subset of transmission strategies. Second, requests need to be served in the FIFO manner. We seek a downlink transmission scheduling algorithm maximizing the overall system utility. We develop an algorithmic framework of the formulated downlink data transmission scheduling problem in both offline and online settings. We first establish its hardness, and then develop approximation algorithms with mathematically proven performance guarantee in terms of approximation and competitive ratios for the offline and online settings, respectively. The third contribution of this thesis concerns the contiguous-resource batching task scheduling. A set of tasks need to be executed on a pool of continuous resource, each requiring a certain amount of time and contiguous resource; some tasks can be executed simultaneously in batch by sharing the resource, while others requiring exclusive use of the resource; tasks are served in the FIFO manner. We seek an optimal resource allocation and the related scheduling policy maximizing the overall system utility. We deliver a comprehensive algorithmic analysis on the problem by establishing its hardness and developing approximation scheduling algorithms for both offline and online settings

Pełny tekst źródłaUnlike methods with numerical techniques, there are practically no limitations for the number of individual piles under the raft, size of the group and the group shape or layout. It can also be applied to piles with different length or piles that are located within multi-layered soils.
The raft is designed first according to the allowable settlement that is pre-defined by the structural requirements and with the necessary factor of safety. When raft suffers excessive settlement, then the load that causes excess raft settlement beyond the required limit is to be transferred to the fully mobilised frictional piles.
The fully mobilised shaft (with no end bearing) piles are designed with factor of safety close to unity since their function is only to reduce raft settlement and since the raft has an adequate bearing capacity.
Geometry of these piles is chosen to fully mobilise their shafts capacity with low settlement level in order to comply with load/settlement requirement and reduce raft settlement to the pre-defined level.

Pełny tekst źródłaUser Action Notation (UAN) is a useful technique for representing user interaction designs in the behavioral domain. Primary abstractions in UAN-expressed designs are user tasks. Information about interface objects is encapsulated in user task descriptions and scenarios. Primary abstractions in a GUI such as Motifâ ¢ are interface objects. Motif implements objects' behavior and appearance using system functions that are encapsulated within pre-defined object classes. Therefore, user interaction developers and software developers must communicate well to translate UAN-expressed interaction designs into Motif-based software designs. Translation is not trivial since it is a translation between two significantly different domains.
This thesis contributes to understanding of the user interface development process
by developing a foundation to assist translation of user interaction designs into Motif-based
software designs. This thesis develops the foundation as follows:
1. Adapt UAN for use with Motif.
2. Summarize Motif concepts about objects and object relationships.
3. Develop new approaches for discussing objects and object relationships.
4. Develop a partial translation guide containing VAN descriptions of selected
Motif abstractions.

Pełny tekst źródłaRigid inclusions represent a further development of combined pile-raft foundations, comprising a load transfer platform between the columns and the structure. Calculation methods and design concepts are available for such combined systems in particular in France, based on measured pressuremeter modulus values and on the French recommendations ASIRI for rigid inclusions (IREX 2012). The conventional pile design consisting only of a bearing capacity check for the individual column cannot be applied to such combined systems. The expected settlements may be larger due to a significant load proportion supported by the soil. The present work contributes to the development of displacement-based calculation methods (advocated by the Eurocode 7, EN 1997-1 2004) and design methods for combined systems under vertical loads, in particular on an international level where in general no in situ soil modulus values are measured. Possible particularities of such systems, like the sensitivity of unreinforced small-diameter columns, also had to be investigated. The load transfer method (LTM) is identified as a straightforward engineering tool for the calculation of combined systems with relatively simple geometries. The soil-column interaction in terms of skin friction and tip resistance is described by deformation-dependent load transfer curves (or “t-z” and “q-z” curves). Continuum methods like the finite element method should be preferred only for complex cases in general. The non-linear load-settlement behaviour of single footings up to failure is analysed based on measurements given in the literature. This yields the proposal of a hyperbolic load-settlement curve for footings. This mobilization curve is defined in a way to match the linear usual method for one third of the footing ultimate load. The behaviour of single piles is investigated based on numerous available instrumented and non-instrumented pile load tests with different pile and soil types. A reliable alternative to the load transfer curves after Frank and Zhao (1982), which are based on the pressuremeter modulus, is sought. Cubic root and hyperbolic axial load transfer curves are proposed for all pile and ground types. The stiffness accuracy of the proposed curves depends on an accurate estimation of the ultimate skin friction and tip resistance values. On the contrary, the initial stiffness of the Frank and Zhao curves is fully described by the pressuremeter modulus, avoiding thus errors in the stiffness. The proposed mobilization curves for the shallow and pile foundation behaviours are combined and extended for all combined systems. The proposed method is implemented as the LTM option into the software KID (Keller company 2015). The prediction with the developed model matches very well the measurements made for 3 different cases from the literature. A parametric study shows a smooth transition between the combined pile-raft foundation case and the rigid inclusion case and a potential for optimisation with a significant reduction of the internal forces in the columns and in the rigid slab when a load transfer platform is used. In addition, a comparison with 3D finite element calculations for a theoretical footing case with columns confirms that the developed load transfer method is very reliable for simple geometries. Sensitivity investigations using the axisymmetric and 3D finite element method with Plaxis (2013, 2014) are performed. Geometrical imperfections impact mainly the structural integrity of small-diameter unreinforced columns. However, these effects are reduced in combined systems compared to the single column case due to the possibility of redistribution of the loads within the system
