It's been a pleasure to work with Dr Akshay Baheti (PhD) and with Professor Dr Vasant Matsagar for the past few years on Akshay's PhD within the UQ IIT Delhi Academy of Research. This article is one of a series of articles that Akshay has written which all together articulate the importance of how we describe fire intensity for structural fire engineering (and the benefits of doing it right!). Well done Akshay! #Fire #Engineering UQ-IITD UQIDAR

📝 𝗡𝘂𝗺𝗲𝗿𝗶𝗰𝗮𝗹 𝗺𝗼𝗱𝗲𝗹𝗶𝗻𝗴 𝗮𝗽𝗽𝗿𝗼𝗮𝗰𝗵𝗲𝘀 𝗳𝗼𝗿 𝘀𝗶𝗺𝘂𝗹𝗮𝘁𝗶𝗼𝗻 𝗼𝗳 𝘀𝗲𝗹𝗳-𝗰𝗲𝗻𝘁𝗲𝗿𝗶𝗻𝗴 𝗿𝗼𝗰𝗸𝗶𝗻𝗴 𝗺𝗲𝗺𝗯𝗲𝗿𝘀 There are several approaches in numerical modeling of self-centering rocking members; (i) 𝐬𝐩𝐫𝐢𝐧𝐠 𝐦𝐨𝐝𝐞𝐥 and (ii) 𝐟𝐢𝐛𝐞𝐫 𝐦𝐨𝐝𝐞𝐥. In the spring model, the rocking joint is modeled with a number of springs. The number of springs determines the distribution of stiffness in the rocking interface. The second approach employs zeroLengthSection elements to model the rocking joint. A fiber section is allocated to the element that can capture the nonlinear behavior and confinement effect of concrete in the rocking region. The spring model is 𝐜𝐨𝐦𝐩𝐮𝐭𝐚𝐭𝐢𝐨𝐧𝐚𝐥𝐥𝐲 𝐞𝐟𝐟𝐞𝐜𝐭𝐢𝐯𝐞 but the fiber model can capture the 𝐧𝐨𝐧𝐥𝐢𝐧𝐞𝐚𝐫 𝐛𝐞𝐡𝐚𝐯𝐢𝐨𝐫 of the rocking region with a better precision. This is a part of our research in which the effect of these two approaches are compared through 𝐪𝐮𝐚𝐬𝐢-𝐬𝐭𝐚𝐭𝐢𝐜 and 𝐝𝐲𝐧𝐚𝐦𝐢𝐜 analyses. The figures of these modeling approaches are also available in this post.

Masonry Walls’ Failure Masonry is one of the oldest construction materials, yet its mechanical behavior remains complex due to inherent uncertainties. Despite considerable efforts using various experimental setups to assess performance, discrepancies arise from different approaches in characterizing in-plane (IP) and out-of-plane (OOP) behaviors. This inconsistency is partly due to the lack of standardized testing machines across laboratories, resulting from cost, time, and capacity limitations, leading to bespoke testing methods. In this context, digital technologies and computational tools offer efficient alternatives to full-scale testing. As such, Dr Jamiu's ongoing project, Digital Advancements in Masonry Testing (DAMT), aims to understand traditional testing methods and develop digital assessment techniques for characterizing IP and OOP failures in masonry walls. In the first phase, Jamiu and his collaborators have published a comprehensive systematic review of experimental assessments of failure mechanisms in masonry walls. This review offers profound insights that will aid in refining design guidelines and standards, thereby advancing the fields of masonry structure engineering, engineering failure analysis, and structural integrity. The study underscores the importance of incorporating real-world scenarios in testing, aligning with the core principles of our research at Construction Informatics and Digital Enterprise Lab (CIDEL), School of Built Environment, Engineering and Computing @ Leeds Beckett University to deliver applied solutions to real-world problems.

🚀⚛️ Impressive physics and the concept of equilibrium taken to the limit! 🔥 In physics, equilibrium refers to a state where the total forces acting on an object are balanced, leading to zero net force and zero acceleration. 👨🏻🏫 There are static and dynamic equilibrium. Static equilibrium occurs when an object is at rest, with all forces and torques balanced, with no movement nor rotations. Dynamic equilibrium implies objects at constant velocity, where balanced forces result in zero acceleration despite the motion. 📍Equilibrium is crucial in civil engineering, and critical for analyzing and designing stable structures and systems in engineering, from machines to architectural buildings. #science #engineering #technology #art #creativity #innovation #STEM ⏩ Felipe Ochoa Cornejo 👨🏻🏫🇨🇱 for more science, engineering, geology, and technology 🎥 Please DM for credit

Excited to share our latest publication! I'm honored to be the first author of this new paper published in Coastal Engineering Journal. (https://lnkd.in/eVEYXR_4)  This work wouldn’t have been possible without the invaluable contributions and collaboration of co-authors (Jeremy Bricker, Stefan Felder, Ries Plescher, EIT, Julien Malherbe, Sirawit Shimpalee). Special thanks to Jeremy and Stefan for guiding the research direction and providing crucial feedback. < Abstract > We investigated air-water flow dynamics and forces on a broad-crested weir with both ventilated and non-ventilated cavity conditions. Key findings show that upstream water depth significantly affects forces in supercritical flow, while downstream depth stabilizes forces in subcritical flow by increasing cavity water depth. Pressure estimates reveal that traditional hydrostatic assumptions fail to capture forces accurately under non-ventilated conditions, highlighting the need to consider dynamic factors in hydraulic design.
