Since nowadays technology is more than ever stretching materials properties towards their limits, nanotechnology has proved as one way forward towards a radically new materials era. Nanotechnology enables additional abilities in composites delivering multi-purpose products. The civil engineering sector has more hesitantly started exploring the benefits of nanotechnology to develop structures with improved performance and secondary features such as self-diagnosing.<span>  </span></span></p> <p><span lang="EN-US">Even though there are several advantages of using composites, let alone nanocomposites, in different applications, there are still drawbacks that need to be addressed with regards to sustainability. The talk will focus on the different benefits of composites and advanced composites and also include ideas on sustainability measures.<br /></span></p> <p><span lang="EN-US">Short biography:</span><span lang="EN-US"></span><span lang="EN-US"><br />Sotirios Grammatikos is a Materials Science Engineer with a MSc in Chemistry &amp; Technology of Materials (2008-2010) and a PhD in Aerospace Materials Engineering (2009-2013).

Public health and economic development rely on access to and the quality of drinking water. Human activities, aging infrastructure, climate change and societal development are, however, examples that pose risks to water supplies – risks that need to be managed. Hence, risk assessments are essential to support decisions on how to improve and protect water supplies. In this lecture, I will show how models have been developed and applied to analyse complex drinking water systems in Sweden and Botswana, how the effects of mitigation measures can be estimated, uncertainties modelled, and how the results combined with additional information can provide decision support. The need of a proper toolbox when assessing risks is illustrated as well as how the ongoing research provides necessary input.</div></div> <div>​<br /></div> <div>Department of Architecture and Civil Engineering, Division of Water Environment Technology<br /></div> <div><br /></div></div> ​ Sundell, Architecture and Civil Engineering<p>SB-H3, lecture hall,</p><p>​​​Risk Assessment of Groundwater Drawdown in Subsidence Sensitive Areas​​</p><div><br /></div> ​​​​Jonas is a PhD student at the Division of Geology and Geotechnics<div><br /></div> <div>Examinator: Ass. Prof. Jenny Norrman, Chalmers</div> <div>Main supervisor: Prof. Lars Rosén, Chalmers</div> <div>Faculty Opponent: Prof. Jens Christian Refsgaard, Geological Survey of Denmark and Greenland</div> <div><br /></div> <div>Abstract:</div> <div>Groundwater leakage into sub-surface constructions can result in drawdown, subsidence in compressible materials, and costly damage to buildings and installations. When planning for sub-surface constructions where there is a risk for land subsidence due to groundwater drawdown, the need for safety measures must be carefully evaluated and managed. Since the sub-surface consists of heterogeneous and anisotropic materials, which cannot be fully investigated in all aspects, decisions regarding safety measures must be taken under uncertainty. In this thesis, a generic framework is presented on how to assess the risk of groundwater drawdown-induced subsidence (Paper I). As specific tools for modelling uncertainties in the groundwater drawdown – subsidence – damage chain, a method for probabilistic modelling of bedrock levels and soil stratification (Paper II) and a method for probabilistic modelling of ground subsidence to a large spatial extent (Paper III) are presented. These are combined with a probabilistic groundwater model and cost functions to calculate the economic risks of subsidence damage between different design alternatives (Paper IV). Finally, a novel method for economic valuation of hydrogeological information is presented in Paper V. The methods presented can distinguish between low and high-risk areas, identify the alternative with the highest net benefit compared to a reference alternative, and estimate the expected benefit of additional information. The methods have been demonstrated to provide useful support for decision-making and communication tools when assessing the risk of large-scale groundwater drawdown-induced subsidence in different infrastructure projects in Sweden. <br /></div> ​​ Pettersson<p>SB-S393, 3rd floor, SB Building, Sven Hultins gata 6</p><p>​Modeling stormwater transport through unsaturated green roof substrates</p><div>​</div> <div>Kaj Pettersson is a doctoral student at the <span><span>Division of Building Technology<span style="display:inline-block">.<br /></span></span></span></div> <div> </div> <div><span><span><span style="display:inline-block"><br /></span></span></span></div> <div> </div> <div>Abstract:</div> <div> </div> <div><div>In recent decades there has been an increase in research regarding green roofs and similar technologies. This increased interest is driven by the requirements of urban development and its effects both on humans and the environment. Additionally, the predicted increase in weather severity in the future is raising concerns on the capabilities of urban environments and their stormwater management systems to cope with the increase.<span> </span><br /><br />Green roofs can be used as a space-conscious solution for improving stormwater management in urban areas as well as contributing to, for example, building protection and pollution and noise reduction. In order to fully utilize them effectively for stormwater runoff reduction it is necessary to quantify their effect and optimize their performance in a given climate. This optimization can take the form of placement on structures or by design within the green roof construction itself.<span> </span><br /><br />This work focuses on optimization of design by applying computational fluid dynamics and lattice Boltzmann theory to the soil growth substrate. Computational fluid dynamics is used for modeling the flow through the green roof growth substrate (soil layer) at the macrososcopic scale while a lattice Boltzmann model is applied to the mesoscopic (soil particle) scale. Using these methods, the efficacy at water retention and drainage of given soil particles and full-sized green roofs can be determined. This work covers the framework covering both scales however the methodology is applied only to the mesoscopic scale.<span> </span><br /><br />The focus within the mesoscopic scale is primarily on the hydrophilicity of the particles in the soil and its impact on liquid imbibition. Also included is an exploration on the liquid-air interfacial area and liquid penetration depth to aid in the analysis of the results. The findings of the study suggest particle hydrophilicity plays an important role in the imbibition process, particularly under light to medium rainfall conditions. In addition a pore blocking phenomenon is identified which requires further analysis. Finally, plans for future work and the closure of the two-framework methodology proposed in this work is discussed.</div></div> <div> </div> <div><div> </div> <h6 class="chalmersElement-H6">Examiner: Carl-Eric Hagentoft, <span><span>Division of Building Technology<span>,</span></span></span> Chalmers</h6></div> <h6 class="chalmersElement-H6"> </h6><h6 class="chalmersElement-H6">Supervisor: Angela Sasic Kalagasidis, <span>Division of Building Technology,</span> Chalmers</h6><h6 class="chalmersElement-H6"> </h6><h6 class="chalmersElement-H6"> Discussion leader: Tone M.

Furthermore, it describes the key mechanisms for water leakage in defects in the outermost layer of external walls. A new algorithm has been developed and validated based on the empirical measurements of water leakage. In order to produce accurate calculations for water leakage, the geometry and dimensions of the defects need to be precisely defined. Extensive data is presented in this thesis that facilitates relatively reasonable assumptions of the water leakage flow, even though the geometry and dimensions of the defects are unknown.</span></p> <p><span lang="EN-US">The aim is to improve knowledge, generate more data and developing a calculation algorithm for water leakage flow. This would increase the ability to produce more accurate two or three-dimensional moisture calculations and reliable probabilistic risk moisture analyses.</span></p> <p><span lang="EN-US">The research is mainly based upon laboratory testing and experiments, and field measurements. </span></p> <p><span lang="EN-US">The results point out that water leakages are almost always expected in small concealed or invisible defects in façades with façade details such as window-wall interfaces, etc., regardless of the façade type and façade systems such as unventilated, ventilated and pressure-equalized façades.</span></p> <p><span lang="EN-US">Four of the greatest importance for the water leakage flow in experimental trials were; façade material, the size of the hole, the size of the dam and hydrostatic pressure derived from the building. Additional two factors are pressure difference across the façade layer and water flow on the façade due to driving rain which derives mainly from the prevailing weather conditions. </span></p> <p><span lang="EN-US">In order to use the algorithm, the important factors, as mentioned above, need to be considered together with a table that has been prepared with the constituent constants. </span></p> <p><span lang="EN-US">Based on an assessment of all the results and assuming carefully completed assembly, it is reasonable to assume that the water leakage flow through each point leakage corresponds to 0.5-2% of the vertical water flow cross a unit width of the façade at the given height. The lower proportion within the range only refers to holes/slits, while the higher proportion refers to holes/slits with dams.</span></p> <p><span lang="EN-US"> </span></p> <p><span lang="EN-US">Key words: driving rain, water leakage, rain resistance, hole, obstacle, dam, protrusion, deficiency, water flow, catch area, leakage flow, façade details, window-wall interface, fenestration, EN 12865</span></p> </div> Thodelius, Architecture and Civil Engineering<p>Scaniasalen, lecture room,</p><p>​Rethinking Injury Events.
