The blog post from #MIDAS highlights how differential equations play a crucial role in understanding complex phenomena like column buckling and structural dynamics. 🔗 Read more on https://lnkd.in/gTMTJGCK Dive into this insightful read to appreciate how foundational math concepts are not just academic exercises but essential tools for advancing our engineering practices #CivilEngineering #StructuralDynamics #EngineeringMathematics #Innovation #EngineeringExcellence #CivilEngineering #StructuralEngineering #DifferentialEquations #ColumnBuckling #CAE #EngineeringEducation #InnovativeEngineering #MathInEngineering #BlogPost #MidasBlog #MIDASBridge #midasCivil #MidasIT #MidasIndia

Just completed a comprehensive course "Cities, Climate and Change, Pathways and opportunities " on Coursera from Lund University Sweden, applying theoretical knowledge to practical problems. This experience has not only sharpened my skills but also fueled my passion for development of smart cities and communities and impact of climate changes like flooding, tsunamis, groundwater level, earthquake, landslides, soil erosions etc on civil engineering structures.

Do you have hopes, dreams or goals for your personal life and professional career? Do you know the difference between a hope, a dream and a goal? A goal is a dream with a finish date. I wanted to share a dream that will become a goal in early 2025. After raising three wonderful children for 25 years, we will be empty nesters with all kids graduated and in their own. To add to that family goal, I put my dream of working on my Masters degree in Civil Engineering (structural/geotechnical engineering) on hold and this will now become a goal I 2025 at age 57. Goal #3 - I will be taking the P.E. Exam I. 2025 (1st time) Why? To let you know that age is just a number….goals cause you to stretch yourself, and in doing so, cause you to grow. How long will you hold into your dreams so you can turn them into goals? What are you waiting for? What is holding you back?

🚨 New Research Alert! 🚨 Excited to share my latest paper on the design of reinforced concrete (RC) linings in hydraulic tunnels, addressing key gaps in our understanding of their hydro-mechanical behaviour. While much of the literature has explored RC tunnel linings during filling and steady-state conditions, some crucial aspects remain under-addressed, risking under-dimensioning of these structures. The paper introduces a new analytical framework that provides deeper insights into: • 𝗪𝗮𝘁𝗲𝗿-𝗳𝗶𝗹𝗹𝗲𝗱 𝗴𝗮𝗽 between the lining and rockmass and its significant impact on system behaviour. • The 𝗽𝗿𝗼𝗴𝗿𝗲𝘀𝘀𝗶𝘃𝗲 𝗰𝗿𝗮𝗰𝗸𝗶𝗻𝗴 process of linings, with possible stabilization before reaching a fully-cracked state, resulting in fewer cracks than previously assumed. Understanding this process is vital for accurately setting up initial conditions for transient events, which is critical for the fatigue design of the rapidly growing 𝗣𝘂𝗺𝗽𝗲𝗱 𝗦𝘁𝗼𝗿𝗮𝗴𝗲 𝗦𝗰𝗵𝗲𝗺𝗲𝘀 (𝗣𝗦𝗣𝘀) used for grid stabilization. Looking forward to connecting with fellow researchers and engineers interested in this area! #HydraulicTunnels #CivilEngineering #PumpedStorageSchemes #ReinforcedConcrete

Civil Engineers, meet your Greek alphabet allies! ️ These Greek letters are more than just fraternity symbols: Α (Alpha) - Alpha: Not commonly used in Civil Engineering, but the first letter sets the stage! Β (Beta) - Beta: Can represent an angle (e.g., β = 45°) Γ (Gamma) - Gamma: Used for unit weight of soil (γ) Δ (Delta) - Delta: Represents change (e.g., ΔT = change in temperature) Ε (Epsilon) - Epsilon: Used for strain (ε) Σ (Sigma) - Sigma: A powerhouse! Represents stress (σ), summation (Σ) for forces or moments. Φ (Phi) - Phi: The golden ratio, used for aesthetically pleasing & structurally efficient designs. Π (Pi) - Pi (π): The ratio of a circle's circumference to diameter, crucial for columns, beams, etc. Ω (Omega) - Omega: Represents ultimate (maximum) capacity (e.g., ω = bearing capacity of soil) #CivilEngineering #GreekAlphabet #EngineeringLife

Structural Analysis 2 is a course that typically covers advanced topics in structural analysis, including - Moment Distribution Method - Column Analogy Method - Slope Deflection Method - Kani's Method of Rotation Contribution - Advanced Methods of Analysis like Matrix Method of Structural Analysis - Introduction to Plastic Analysis - Analysis of indeterminate structures - Curved beams and unsymmetrical bending - Influence lines for determinate and indeterminate structures The course is usually taught to undergraduate civil engineering students and is a continuation of Structural Analysis 1. It provides students with a deeper understanding of the theoretical aspects of structural analysis and their application to practical problems.

Orthogonal Matrices: The Rotators of Civil Engineering! 🔄 These special matrices preserve length and angles, making them invaluable for transformations and rotations in civil engineering. From coordinate system changes to structural analysis, orthogonal matrices help us simplify complex problems and achieve accurate results. #civilengineering #matrices #orthogonalmatrix #rotations #transformations

Stats for strong structures! Here are 5 probability & statistics formulas civil engineers use daily: ️ Mean (AVG): What's the 'average' value (e.g., concrete strength across samples)? Standard Deviation (SD): How 'spread out' is our data (e.g., how much concrete strengths vary)? Probability of Failure (PoF): Helps assess the likelihood of a structure failing under load. ️ Material Strength Distribution: Shows the probability of finding a material with a certain strength. ⏱️ Traffic Flow Prediction: Uses probability to predict future traffic volume on a road. #CivilEngineering #Statistics #Probability #BuildingScience
