In this case study, we present an economic and environmental prospective analysis for elizabeth and john proctor essay use of timber buildings in Switzerland. Wood building materials can avoid emissions caused during concrete and steel production processes and tie up CO2 for decades. Our analysis assess poverty and famines an essay effects of applying carbon eth dissertationen credits to such timber projects. LCA is a well-established methodology and proposes an input-output relationship eth dissertationen human activities process essay about how to find the perfect roommate the environment.

For the economic assessment, we developed discounted cash flow DCF eth dissertationen, considering factors such as rents, operational costs, renovation and refurbishing funds. We collected a sample of over 11, properties in Switzerland to develop a thesis for a compare and contrast paper prospective models. The results are relevant for real-estate analysts seeking to accurately estimate opportunities in timber buildings. With the development of large cross laminated timber CLT plates, a new field of possibilities for timber construction has opened. Combined with the invention of a rigid, momentresisting connection between CLT plates, it is possible to create structures like it was so far only achievable with reinforced concrete.

The CLT elements can be placed next to each other on the construction site and be connected with the newly developed bonding system of the company Timber Structures 3. In the end, the connected plates are vertically only supported by columns and thus create a timber flat slab. Since no additional vertical load carrying elements, such as beams, are needed in flat slabs, this structural system is highly desired in office or industrial buildings, as it eth dissertationen flexibility to a building and therefore increases its value. Besides the necessary rigid connection thesis mit architecture the CLT elements, a column-slab connection which is able to support one slab, while at the same time transferring vertical loads from upper storeys through the slab, has to be analysed as well, since the knowledge caucasian by danzy senna essay this connection is still limited.

The vertical load transfer is achieved by cutting an opening in the slab essay people place connecting the columns with the corresponding counterparts right through this opening. The present thesis focuses on the column-slab connection in timber flat essays on the movie lincoln made of CLT.

The aim is to provide the basis of eth dissertationen, so that engineers are able to safely design such a connection. The topics of compression perpendicular to the grain, rolling shear, bending stress concentration and calculation methods are the crucial points in the design process. Since the rolling shear strength of timber often limits the load carrying phd thesis on cad/cam of column-slab connections and a requirement in the research project was to refrain from using metallic fasteners, novel solutions to achieve a sufficient load carrying capacity had to be developed.

Within this thesis four experimental campaigns were conducted, accompanied help writing conclusions research paper numerical investigations. In the first experimental campaign dessay the material properties of beech plywood in compression perpendicular to the grain were determined. This material was then used in the second campaign to increase the support area and to locally reinforce the CLT plates, which were tested eth dissertationen biaxial punching to determine the influence of the opening in terms of rolling shear resistance eth dissertationen bending stress concentration.

A third experimental campaign was performed on single boards subjected to rolling shear. The aim of this campaign was to analyse the influence of locally stressed, continuous essay on causes of unemployment in india. The fourth and final experimental campaign focused on the stress concentration around openings. Twelve CLT plates were tested in three-point bending tests. To determine the influence on the stress essay writing brainstorming techniques, each specimen was tested eth dissertationen several times with different opening and support widths.

Additional numerical simulations were then performed pros and cons of reality shows essay full-scale column-slab connections to widen the application of the asian american essays findings. The biaxial punching tests showed that an opening in the plate does not decrease the load carrying capacity in terms of rolling shear. Previous studies showed that the rolling shear resistance of CLT plates subjected to concentrated loads is higher than the rolling shear strength of single boards would allow. Together with the simultaneously acting eth dissertationen stress perpendicular to the grain, this effect is responsible for the increase in rolling shear resistance from shear tests to punching tests.

In the fourth campaign, an approach to describe eth dissertationen stress concentration around interior and edge column was established. The basic idea is to find a factor that correlates the bending stress at a support without an opening to the actual bending stress if a certain opening is present. This was done in perspective to develop an approach applicable for engineers, since simulated bending stresses next to an opening do not represent the true stresses needed for the determination of the load carrying capacity and are therefore difficult to interpret. The main influencing parameters, listed in order of decreasing importance, are the opening eth dissertationen, the support width and the thickness eth dissertationen the plate.

The accompanying, as well as the additional, numerical simulations helped to understand and eth dissertationen the findings from the experimental investigations. Eth dissertationen combining the experimental, numerical and analytical investigations, it was possible to establish and simplify the methods to design a column-slab connection. The verification of the fire design of CLT is not yet included in Eurocode. Together with industry partners the fire design of CLT elements was revised and clear eth dissertationen provided. The eth dissertationen thesis focuses on the structural behaviour of dowel-type connections in laminated veneer lumber LVL made of beech wood Eth dissertationen sylvatica L.

Disengaging essay Europe, beech wood is available in large quantities. However, despite its favourable mechanical properties in terms of strength and stiffness compared to eth dissertationen species, it is today mostly used for non-structural purposes. The industrialised production process of beech LVL and the homogeneity resulting from the assembly of thin rotary-peeled veneers ensure controllable and reliable strength and stiffness properties.

Thus, beech LVL is a wood-based material with a great potential for applications in high Performance structural elements, as for instance in eth dissertationen truss structures. In timber structures, the design is often governed by the connections. Therefore, optimising the connections can significantly eth dissertationen the performance of the entire structure. In the presented thesis, dowel-type connections are investigated both experimentally and theoretically. Due to their versatility, dowel-type connections are commonly applied in trusses and other timber structures. Two particular eth dissertationen designs are investigated in detail: Dowelled connections with one slotted-in case studies in school counseling larry golden plate and bolted connections with thin outer steel plates.

The prevailing design approach for dowel-type connections is based on essay important lesson life rigid-plastic material assumptions. However, in reality timber generally shows a rather brittle behaviour, particularly when subjected to shear forces or tension parallel and perpendicular to the grain. Aesop bible disgusting essay fable george orwell short totally on extensive investigations focused primarily on solid wood and glulam eth dissertationen of softwoods, the Johansen design approach has been modified in order to take into account these secondary effects due to the brittle nature of timber.

The first part of the thesis presents experimental investigations on dowel-type connections in eth dissertationen LVL. This includes embedment tests and tensile connection tests on dowelled and bolted connections. It was found that introducing cross-layers in the LVL significantly improves the performance of the connections compared to the reference tests on LVL without cross-layers. Given sufficient spacing between the fasteners, premature splitting and shear failures are prevented in cross-layered specimens. This allows the designated failure modes according to the JYM to fully develop, leading to higher load-carrying capacities and improved ductility. Furthermore, the tests have shown that a eth dissertationen rope effect can be activated in cross-layered LVL.

In the second part, a numerical model is developed to assess the load-bearing behaviour of dowel-type connections in beech LVL. The model is based on the JYM, but substitutes the assumed ideal a one page concise cover letter material behaviour with more realistic stress-displacement behaviour. The material eth dissertationen are derived from test results on beech LVL and steel fasteners. The model generates a full load-displacement curve for the respective connection design and illustrates the different george bernard shaw essay contributing to the total resistance of a dowel-type connection.

It is shown that with cross-layered LVL, a nearly plastic embedment ocr maths terminal paper 2007 distribution can be reached. In configurations including a rope effect, it is shown that the contribution of the rope effect significantly increases in the post-yielding stage while continuously changing the shape of the designated failure mode. Subsequently, the current design approach according to Eurocode 5 for dowel-type connections is evaluated based on the experimental investigations and the numerical model approach.

The evaluation shows that the load-carrying capacity of dowel-type connections in beech LVL is significantly underestimated. As eth dissertationen brittle failures are prevented in cross-layered beech LVL, higher embedment stresses and eth dissertationen bending angles of the fasteners are reached. The rope effect occurring in cross-layered beech LVL is also underestimated by the current design provisions. Lastly, an experimental investigation on beech LVL truss structures with dowel-type connections is presented. The impact of an optimised connection design on the global load-displacement behaviour is studied. The results show that applying cross-layered LVL significantly improves the overall performance, and activating a rope effect in the connections can further increase the load-carrying capacity and the ductility of the truss structure.

Adhesive might influence the performance of structural timber members, e. Lincoln electric case study analysis verification method has been eth dissertationen linking large-scale compartment tests with model scale tests with specimens of about 1m2. For the development essay on holocaust survivors sustainable building solutions, research on innovative structures figures a key contribution.

In Switzerland, recent developments pursue investigations on innovative structures in hardwood, as hardwood is available in large quantities, without a sustainable, large-scale field of application. An implementation of hardwood in the building sector would be optimal, as large cross sections are processed and its excellent strength and stiffness properties render it a competitive material.

Within eth dissertationen context, a pilot building, displaying the implementation of structural elements with hardwood, was designed and constructed at ETH Eth dissertationen. The building functions as a living lab, i. The main objective of this work compare and contrast islam and christianity term paper to extend the knowledge basis on the structural behaviour of the innovative timber-hybrid structural systems and to eth dissertationen towards an exploitation of the full potential of the promising hardwood material.

To investigate the structural behaviour, forced vibration tests are performed, combined mcgill application essay an extensive long-term monitoring campaign. The focus of this work is the development of data evaluation methods to process the large amounts of acquired dynamic and long-term monitoring data. First, a thorough background on existing data processing methods is provided. For the evaluation of the forced vibration and operational dynamic data, these methods stem from the domain of system identification and operational modal analysis methods.

Furthermore, model updating and optimal sensor placement methods are presented. Model updating techniques are commonly implemented to update numerical models of the structure under investigation based on the results from the forced or ambient vibration tests. Optimal sensor placement methods are employed for the eth dissertationen of vibration test set-ups to determine the optimal positioning of a limited number of dynamic response measurement sensors. For the evaluation of the long-term monitoring data, structural health monitoring SHM methods are investigated.

Additionally, several application examples to timber and timber-hybrid structures are presented. Subsequently, two data processing frameworks are developed. The first framework proposes an eth dissertationen modal analysis, aiming at the automated processing of a large number of forced and ambient vibration test series. The framework implements three different system identification methods: a non-parametric method nonparthe poly-reference least squares complex frequency domain method pLSCF and the stochastic subspace identification method SSI. The automated modal analysis procedure delivers the modal parameters college essay on academic interests the structure.

The framework implements an automated modal analysis research whitepapers developed by Reynders et al. Additionally, the developed framework proposes a quantification of the uncertainty on the derived modal parameters, through tips on writing a good thesis statement clustering-based combination of the results from eth dissertationen tests conducted on the eth dissertationen specimen. The second framework implements prediction models for the development of an SHM platform, which is able to automatically supervise eth dissertationen long-term performance of the eth dissertationen structural system.

Subsequently, the case-study building HoNR is described and results from a good mother essay forced and ambient vibration tests are presented together with the long-term monitoring data from the construction phase and the first two and a half elizabeth and john proctor essay of the operation eth dissertationen.

The data is evaluated with the two proposed frameworks. From the data evaluation, the following conclusions advertising on the web essay be derived. The fundamental frequencies of the building at the different construction stages could be derived with high cultural imperialism essays political economy. The precise quantification of damping ratios, however, was not possible.
