Abstract:

Limiting the fire spread through lightweight framed construction is a well established method of providing fire resistance. The objective is for the barrier to provide fire resistance for the required time, even if at the end of that time it has to be demolished, because of internal damage. This report describes a software tool for predicting the likely fire resistance performance of a non-loadbearing or loadbearing wall subjected to a standard fire resistance test, or when subjected to real fire conditions. Prediction of the performance of fire barriers in this study employed finite differe

Abstract:

Designing structures for lightness is an intelligent and responsible way for engineers and architects to conceive structural systems. Lightweight structures are able to bridge wide spans with a least amount of material. However, the quest for lightness remains an utopia without the driving constraints that give sense to contemporary structural design.<p><p>Previously proposed computational methods for designing lightweight structures focused either on finding an equilibrium shape, or are restricted to fairly small design applications.

Abstract:

A parametric design study of light weight mirror shapes with various support conditions was performed utilizing the finite element program NASTRAN. Improvements in the mirror performance were made based on the following design criteria: (1) minimization of the optical surface wavefront variations, (2) minimization of the self-weight directly related to cost of manufacturing, and (3) optimal location of support points. A pre-processor to automatically generate a finite element model for each mirror geometry was developed in order to obtain the structural deformations systematically. Additionall

While there are major concerns with decks in 75% of structurally deficient bridges, often weight and geometry of the deck further limit the load rating and functionality of the bridge. Traditional deck systems and construction methods usually lead to prolonged periods of traffic delays, limiting options for transportation agencies to replace or widen a bridge, especially in urban areas.

The primary aim was to provide a laboratory method for characterisation of lightweight stairs as structure-borne sound sources, which will give input data for prediction of the sound transmission in heavyweight building situations. By treating the stair system, combined with impact source(s), as an active component, available methods for active sources could be adapted.

Abstract:

Optimized slender and short-thick beams are used in building, aircraft and machine structures to increase performance at a lower material cost. A previous work proposes an optimum shape, material and size selection model to design lightweight slender beams under pure bending. In short-thick beams, the transverse shear effects are no longer negligible and impact the choice of the optimum shape. This work extends such an optimum selection model to consider both slender and short-thick beams, by formulating the total beam stiffness design requirement as a combination of shear and bending stiffnes

Structural lightweight aggregate concrete is an important and versatile material, which offers a range of technical, economic and environmental-enhancing and preserving advantages and is designed to become a dominant material in the new millennium. For structural application of lightweight concrete, the density is often more important than the strength. A decreased density for the same strength level reduces the self-weight, foundation size and construction costs.

The use of cellular foam as a core material in light-weight structural applications is of considerable interest. However, advances in this technology have been limited due to the lack of information concerning the macroscopic material behavior of cellular foams. Of particular interest in the design of composite structures is the shear modulus, G, of the core material, which must be established with a high degree of accuracy. Current ASTM test methods for shear modulus determination were researched and found inadequate for testing cellular foam materials. The difficulty in testing foam and the

Abstract:

Lightweight design in rail vehicles has been important for quite some time. Structures have been optimised to fulfill their purpose and cut unnecessary weight to reach allowable axle loads. Classically this is done by using steel, thin-walled structures, throughout the car body, or, alternatively, power-pressed aluminum profiles. The use of composites and sandwich structures has, however, been somewhat limited in the railway industry, especially when considering High-Speed trains. The anticipated weight savings, and reduced complexity of this type of structure are believed to have great potent

Abstract:

La gestion des déchets agricoles et la promotion de matériaux de construction durables offrent de nombreux avantages considérables. En intégrant des pratiques durables dans le secteur de la construction, nous avons la capacité de réduire notre empreinte écologique en limitant l'exploitation excessive des ressources naturelles.La recherche menée dans la présente étude vise à développer un béton et un mortier de ciment structurels allégés avec des agrégats organiques de grignons d’olive. Deux types d’agrégats ont été utilisés selon qu’ils soient mélangés ou non avec des margines. L'objectif prin

Abstract:

<p>In 2002 an amendment was added to the International Convention for the Safety of Life at Sea (SOLAS) which opened up for shipbuilders to replace steel with lightweight materials in the superstructures. However, SOLAS requires equal fire safety compared to ships with steel superstructures.</p><p> </p><p>LASS-c is a cross-organizational project with the aim to find a method to build cruise ships with part of the superstructure made in lightweight materials. As a part of the LASS-c project the purpose of this thesis has been to develop an application in Java (FISPAT). The tool has been designe

Abstract:

The master’s thesis analyzes different methods of comparing structures in terms of thermal stability in summer. An important part is the evaluation of the results accuracy and computational models of these methods. In conclusion it describes the influence of building envelope on the thermal stability of the internal environment in the summer, which are important design parameters and how to optimize the design of wall.

Abstract:

Les bétons légers, formés des fibres de bois et d’une pâte de ciment Portland, constituent une nouvelle alternative à explorer pour réduire l’impact environnemental des bâtiments. Ils sont utilisés dans la construction durable, comme des éléments secondaires, pour leurs performances thermiques, hydriques et mécaniques. Cependant, la généralisation de leur utilisation dans le bâtiment ne sera rendue possible sans résoudre certains verrous scientifiques liés à leur caractérisation et à leur formulation. Le présent travail s’inscrit dans cet objectif. Il s’agit de contribuer à la caractérisation

Abstract:

La forte sensibilité des ouvrages bois aux transmissions latérales, vibrations et autres sons basses fréquences représente un obstacle à leur développement. En réponse à cette problématique, le projet Vibracoubois, dans lequel s'inscrivent ces travaux, vise à développer la caractérisation ainsi que la modélisation des transferts vibro-acoustiques au sein de ces structures. L'objectif principal de ces travaux est donc d'élargir le champ de l'étude expérimentale et numérique à une structure complète constituée de différentes parois et de cavités couplées. Les jonctions, véritables nœuds des syst

Abstract:

Steigende Anforderungen an die Leistungsfähigkeit und Effizienz von Triebwerken lassen sich durch den Einsatz von Metall-Faserverbund-Bauweisen erfüllen. Faser-Kunststoff-Verbunde (FKV) mit ihren herausragenden und einstellbaren mechanischen Eigenschaften bieten das Potential, die Masse strukturell hochbelasteter Komponenten zu reduzieren. Durch die richtungsabhängigen Eigenschaften kann der FKV zielgerichtet für die Anwendung angepasst werden. Die Vielzahl der einstellbaren Parameter in Kombination mit der Entwicklung von komplexen Triebwerkstrukturen führt zu einem interaktiven und interagie
