Lateral Load Resistance of Glass Pane According to EN 16612

In this video, Martina Eliášová introduces the European standard EN 16612 for determining the lateral load resistance of glass panes used as infill panels in windows and facades. The standard provides design procedures for monolithic, laminated, or insulated glass that is simply supported around its edges and subjected to uniform loads like wind or thermal stress. The design follows the limit state method, which includes checking the Ultimate Limit State (to prevent collapse by ensuring design tensile stress is less than the design glass strength) and the Serviceability Limit State (to control deformation). A key aspect is the use of partial safety factors, where design loads are increased and material strengths are reduced. The design bending strength of glass is significantly influenced by the load duration (through the Kmod factor), the edge condition (Ke factor), and the glass surface profile (Ksp factor), with specific characteristic strength values and adjustment factors provided for different glass types like annealed and pre-stressed glass. The video was produced by the Open GLASSroom project. Special thanks to Martina Eliášová for contributing to the Open GLASSroom OER collection.

Comparative Analysis of the Glass Plate Design

In this video, Ivana Rakić presents a comparative analysis of the economic impact of designing glass elements according to different standards, focusing on the new European draft standard FprEN 19100-1(2,3):2023, the existing EN 16612:2019, and the American ASTM E1300-16. The study examines common double-glazed insulating units under wind load, using the minimal required glass thickness for loadbearing resistance as the key comparison criterion. The results indicate that for annealed glass, all three standards yield similar economic outcomes. However, for heat-treated glass like heat-strengthened and thermally toughened glass, the new FprEN 19100 standard leads to a lower capacity utilisation factor, making it the most economical design choice, while the ASTM standard is the least economical. The analysis concludes that the choice of standard significantly influences design economy and highlights the need for further research incorporating factors like safety and long-term performance for a more comprehensive understanding.

Fracture Mechanics Fundamentals

In this video, Daniel Trias Mansilla explains the core principles of fracture mechanics, which provides an alternative to traditional stress analysis by accounting for the inherent cracks and defects in real materials. The field introduces two main criteria for predicting failure. The first is an energy-based approach, using the energy release rate (G), which measures the energy available to propagate a crack. The second is a stress-based approach, using the stress intensity factor (K), which characterizes the intense stress field near a crack tip. Fracture occurs when either of these values reaches a critical threshold (Gc or Kc), which are material properties known as fracture toughness. These concepts allow engineers to predict failure in flawed components more accurately than traditional methods. The video was produced by the Open GLASSroom project.

Thermo-optical Properties

In this video, Francesco Fiorito, from the Polytechnic University of Bari, explains how glass interacts with solar radiation. When sunlight hits a window, some energy is transmitted inside, some is reflected, and some is absorbed. Two key values define a glass's performance: the Solar Factor (or g-value), which measures total heat gain, and the Visible Light Transmittance (VLT), which measures how much light passes through. While clear glass has high values for both, it can cause overheating. Tinted glass reduces heat gain but also makes interiors darker. Selective glass uses special coatings to block heat (a low g-value) while still allowing plenty of light (a high VLT). Other coatings, like low-emissivity (low-e), help with thermal insulation. The video concludes that selecting the right glass is essential for energy efficiency and comfort in buildings. The video was produced by the Open GLASSroom project.

Math anxiety with Sanne van der Ven | In a Nutshell

Why are we afraid of math? Can you make peace with the school subjects you hate? And how important are feelings and attitudes towards a subject when it comes to doing well? (Spoiler alert: very.) Everyone has that one subject in school (or at university) they don’t like – and in today’s episode, Antonia is tackling precisely that: the subjects we dislike and the disciplines we are bad in. Or, at least, feel like we are. Together with guest Sanne van der Ven, Antonia explores the interplay of cognition, emotions and school performance. And, more importantly, how to (at least somewhat) overcome it. Sanne van der Ven is an assistant professor at the Behavioural Science Institute (BSI). She explores children’s differences in subjects like mathematics, reading and spelling and how cognition and emotions can factor into school performance. Would you like to learn more about math anxiety and the science behind it? Then follow Sanne’s advise and have a take at the YouTube documentary about dyscalculia (in Dutch).

Reclaiming Our Humanity in Times of AI | Radboud Reflects Lecture by Philosopher Shannon Vallor

Artificial Intelligence is in many ways a reflection of ourselves, for better or for worse. When we feed AI-algorithms with imperfect or biased data, they inevitably feed our faults back to us. But can AI also be used to boost humanity’s greatest strengths? Come listen to philosopher Shannon Vallor and see AI in a new light. Reclaiming Our Humanity in Times of AI | Lecture and conversation with philosopher Shannon Vallor Monday 30 September 2024 | 20.00 – 21.30 hrs | LUX, Nijmegen Radboud Reflects, Radboud Centre Social Sciences, SIAC, School of Artificial Intelligence and Workgroup The Human Factor in New Technologies

Radboud Science Snacks | Populisme

Populisme bestaat al zo lang politiek bestaat, maar is niet verbonden aan een politieke richting. Zowel links als rechts kan populistisch zijn. De grootste verbindende factor, weet politicoloog Maurits Meijers van de Radboud Universiteit: het volk vs. de elite. In de ultrakorte podcast Radboud Science Snacks vertellen wetenschappers van de Radboud Universiteit over een klein onderdeel van hun vakgebied, in de tijd dat het jou kost om een bak popcorn leeg te eten. De onderwerpen zijn zaken waar je op de middelbare school over hebt geleerd, maar waarvan je nu weer vergeten bent hoe het precies zit: denk aan neutronensterren, Artikel 1, schimmels, stress, anarchie en nog veel meer. In 5-10 minuten praat een onderzoeker je helemaal bij. Radboud Science Snacks, snack je vol met kennis!

Who Nose? A workshop on smell and 21st Century Learning

Smell has long been part of education. Doctors for example would learn how to smell urine samples and diagnose based on the smell, sight and (yes) taste of the urine. A wine taster needs to learn how to tell the differences between types of wine and to describe the bouquet of the wine, and a perfume maker needs to train their ‘nose’ too. Histories of smell show the importance of odour in understanding issues of class, hygiene and sanitation. Smell has however been a more neglected sense in education and research more broadly, despite its strong links to emotion and memory. In these workshops, you will train your sense of smell and consider how sensing in a different way might help you to address the issues of your challenge owner and the challenge they pose. How might a sensitivity to smell help you address the challenge? How might you use smell to inform your investigation, and maybe even make it part of the intervention? How smell as a research tool and could inform investigation, specifically to think about how smell might be important: During the research phase (as a tool to take other people’s perspective, to come up with new questions for the Challenge Owner and other stakeholders involved); For analytical purposes to think through their challenges more conceptually; And also as a potential factor for the interventions that they will come up with further along their trajectory. Activities: Tutorial 1 Part I Introductions – in pairs, discuss a strong smell memory from “home” (whatever that means to you), and share this with the group Smell kit exercise – a commercial smell kit is passed around and we will describe the smells Anna will introduce some different research on smell, from interdisciplinary perspective, including her own research in medicine education as well as examples from other fields (e.g. marketing), as a way to lead discussion Part II We will then brainstorm what it might mean to make a smell kit relevant to your challenge owner and challenge. Each presents their challenge, while this student presents, the others jot down questions and smell impression on post-its and share afterwards. Encourage students to identify areas that they would appreciate feedback on. Then as a group they brainstorm together using the following questions as prompts: – What might attention to smell open up? – How might smell open up questions about the material things that they challenges are made of? – What kinds of smells would elicit some of these questions/solutions? – How might you go beyond discussion of how smell features in their projects to thinking critically about this together? – What are the histories of some of the smells (we can use tools in class such as the Odeuropa Smell Explorer to explore this: https://explorer.odeuropa.eu/) – How smell is relevant at different times in their project, or for different people? Between tutorials collect materials to bring to the next class to make a smell kit. These may be literal or representative connections to the challenge. Students are encouraged not only think about smell in a literal sense but how it connects to theory. Tutorial 2 – Making a smell kit* Part I We head out to the FASoS garden (weather permitting) and see if there are any more materials to collect. We walk in pairs, reflecting with each other on the materials we’ve brought to the session. We form as a group and share what we would put into our kits and why. Questions for each other. Anna will introduce some different interventions using smell, public health to museums, as a way to lead discussion on the possibilities of how smell might be used with their challenge owners. Part II Everyone assembles their kits. Make a small explanatory text accompanying the kit (form open to your creativity), explaining why the smells were chosen and how to use the kit. Group discussion on how the kit/smells may be brought into your group’s challenge. *students may also want to make a smell map instead, see https://sensorymaps.com/
