Väven grundar sig i nyfikenheten för vad som sker i konstnärernas ateljéer och utforskandet i hur ett rum som ofta upplevs som slutet kan vävas samman med aktiviteten i ett hus för folket.  Projektet är placerat söder om Ösmo i Nynäshamns kommun och innefattar ett konsthantverkscentrum där konstnärer får utrymme att producera, leva och lära i samverkan med publika rum och husets besökare. I programmet ryms  konstnärsbostäder för de 12 residerade konstnärerna och deras familjer, verkstäder inom keramik, textil, glas, metall, trä samt två skrivarstugor. Verkstäderna är ständigt närvarande i gestaltningen och har utformats för att låta besökare ta del av konstnärernas arbete, både visuellt och aktivt genom utbildningslokaler, galleri och butik. Syftet med projektet Väven är därmed att undersöka hur ett konsthantverkscentrum som både är utformat för utövarna och besökarna kan se ut samt hur konsten via projekt som dessa kan nå nya grupper och skapa mervärde till en plats. / The project aims to investigate how a house for culture, with a focus on arts and crafts, can be combined and integrated with a house for the people, and to explore how art and culture can reach new groups in smaller cities through projects like this.

The American Society of Heating, Refrigerating and Air conditioning Engineers suggests that the building sector represents over 30 percent of our national energy consumption (Parsons, R., 2001). Embodied energy in components of building construction can represent as much as five to ten years of operating energy. Building materials such as concrete, steel and glass require significant amounts of energy for production, and therefore are important when calculating embodied energy in buildings (Keable, 2007; Rypkema, 2007). Because of the relatively large area and volume of related components, the building enclosure system represents a major factor when calculating embodied energy. Alternative materials could be incorporated by adapting traditional and vernacular building approaches to today's standards, for example, compressing soil blocks for use as external walls in buildings that can be applicable to almost any climate including rainforests and cold climates. As an alternative to high-embodied energy materials used for enclosure systems, compacted earth-based enclosure systems may be a viable option, particularly if developed and applied as a pre-manufactured modular system. This study seeks to both quantitatively and qualitatively explore the potential development of earth-based building curtain wall systems. Using modified ASTM test protocols for building enclosure systems and components, alternative earth-based panels were compared. The results suggest that earth-based panels may be a viable option for curtain wall systems but its performance is highly dependent on the composition of the panels. The results of the tests are summarized. / Master of Science

Cette contribution, en s’appuyant sur un travail expérimental et de modélisation numérique à l’aide de la méthode des éléments distincts, vise l’étude de structures en maçonnerie et de structures en pisé. Pour la partie maçonnerie, notre étude traite tout d’abord de modèles réduits testés sur table inclinable, puis dans un second temps nous avons testé des murs en briques à une échelle représentative. Dans la deuxième partie, nous avons mené des essais sur des murs en pisé sous un chargement en cisaillement, avec ou sans précontrainte axiale de confinement qui correspond à une descente de charge. Une modélisation numérique par la méthode des éléments discrets a été réalisée pour ces différents cas d’étude. La comparaison entre les résultats expérimentaux et numériques, nous a permis, d’évaluer les pertinences et limites de la modélisation via la méthode des éléments discrets (DEM). / This contribution, based on experimental work and numerical modeling using the distinct elements method, aims to study masonry structures and rammed earth structures. For the masonry part, our study first deals with reduced models tested on tilting table, then in a second time we tested brick walls on a representative scale. In the second part, we conducted tests on rammed earth walls under a shear loading, with or without axial prestressing of the containment which corresponds to a descent of load. Numerical modeling using the discrete element method has been carried out for these different case studies. The comparison between the experimental and numerical results, allowed us to evaluate the relevance and limits of modeling via the discrete element method (DEM).

Este trabalho pretende estabelecer bases para a análise de estruturas correntes feitas em taipa de pilão. Esse material, constituído quase que somente por terra obtida no local da obra, tem todas as propriedades do que se chama uma construção sustentável, incluindo um mínimo de consumo de energia, se comparado as estruturas convencionais em aço e concreto. O texto é dividido em três temas principais. O primeiro trata de revisão da pouca literatura técnica existente sobre o assunto, incluindo a descrição das técnicas de construção e de seleção e preparo dos materiais. O segundo abrange a pesquisa feita pela autora no preparo e ensaio de corpos de prova do material, com a intenção de obter parâmetros que são o insumo para a análise propriamente dita de estruturas desse tipo. Esta análise é a terceira parte do trabalho, a qual consiste no processamento de modelos tridimensionais de elementos finitos de estruturas de construções hipotéticas em taipa de pilão. / This work intends to provide basis for the analysis of common structures built of rammed earth. This material, constituted almost entirely of earth obtained in the place where the building will stand, has all the properties of what is known as sustainable construction, including a minimal consume of energy, as compared to conventional steel or concrete structures. The text is divided in three main themes.

The second reports research conducted by the author on the preparation and testing of samples of the material, in order to obtain the parameters needed in the analysis of structures of this type. This is the third part of the work, consisting in the numerical analysis of three dimensional finite element models of hypothetical buildings made of rammed earth.

This study uses a 3D finite element program, calibrated with the results of a full scale instrumented load test on a limited size footing, to estimate the settlement improvement factor for footings resting on rammed aggregate pier groups. A simplified 3D finite element model (Composite Soil Model) was developed, which takes into account the increase of stiffness around the piers during the ramming process. Design charts for settlement improvement factors of square footings of different sizes (B = 2.4m to 4.8m) resting on aggregate pier groups of different area ratios (AR = 0.087 to 0.349), pier moduli (Ecolumn = 36MPa to 72MPa), and with various compressible clay layer strengths (cu = 20kPa to 60kPa) and thicknesses (L = 5m to 15m) were prepared using this calibrated 3D finite element model. It was found that, the settlement improvement factor increases as the area ratio, pier modulus and footing pressure increase. On the other hand, the settlement improvement factor is observed to decrease as the undrained shear strength and thickness of compressible clay and footing size increase. After using the model to study the behaviour of floating piers, it was concluded that, the advantage of using end bearing piers instead of floating piers for reducing settlements increases as the area ratio of piers increases, the elasticity modulus value of the piers increases, the thickness of the compressible clay layer decreases and the undrained shear strength of the compressible clay decreases.

Despite the developments in the last decades, field performance information for short aggregate pier improved ground is needed for future design and to develop a better understanding of the performance of the short (floating) aggregate piers. A full-scale field study was performed to investigate the floating aggregate pier behavior in a soft clayey soil. Site investigations included five boreholes and sampling, four CPT soundings, and SPT and laboratory testing. The soil profile consisted of 8m thick compressible clay overlying weathered rock. Four large plate load test stations were prepared. A rigid steel footing having plan dimensions of 3.0m by 3.5m were used for loading. Four 65cm diameter reaction piles and steel cross beams were used to load the soil in each station. First test comprised of loading the untreated soil up to 250 kPa with increments, and monitoring the surface settlements. Moreover, distribution of settlements with depth is recorded by means of deep settlement gages installed prior to loading. Other three tests were conducted on clay soil improved by rammed aggregate piers. In each station, seven stone columns were installed, having a diameter of 65cm, area ratio of 0.25, placed in a triangular pattern with a center to center spacing of 1.25m. The length of the columns were 3m, 5m in the two station resembling floating columns, and 8m in the last station to simulate end bearing columns to observe the level of the improvement in the floating columns. Field instrumentations included surface and deep settlement gages, and load cell placed on a aggregate pier to determine distribution of the applied vertical stress between the column and the natural soil , thus to find magnitude of the stress concentration factor, n , in end bearing and floating aggregate piers. It has been found that, the presence of floating aggregate piers reduce settlements, revealing that major improvement in the settlements takes place at relatively short column lengths. It has been also found that the stress concentration factor is not constant, but varies depending on the magnitude of the applied stress. The magnitude of stress concentration factor varies over a range from 2.1 to 5.6 showing a decreasing trend with increasing vertical stress.
