I’m thrilled to announce that our research article titled "Large-Scale Direct Shear Testing for Assessing Interfacial Parameters of Natural and Recycled Sand with Geosynthetic Reinforcements" has been published in @ Construction and Building Materials, Elsevier (IF - 7.4). 🌍 In response to the growing scarcity of natural sand (NS) due to urbanisation, our study explores the use of recycled sand (RS) as a sustainable alternative in transportation geotechnical applications. Large-Scale Direct Shear Testing (LSDST) apparatus was designed and fabricated with dimensions of 500 mm x 500 mm x 300 mm at the Civil Engineering Department Mahindra University, Mahindra University, to rigorously test the interfacial parameters between RS, NS, and various geosynthetic reinforcements. 💡 The results from our testing reveal that RS exhibits comparable shear strength to natural sand, making it a viable and environmentally-friendly option for future construction endeavours.

🚨New Paper🚨 w/ Katerina Ziotopoulou, and Bruce Kutter on “Insights from the Numerical Analysis of Axially Loaded Piles in Liquefiable Soils” and its consequences on geotechnical design. 👉https://lnkd.in/dRtvbQ3y 👈. This paper compares the results of the TzQzLiq analysis (accounting for ue generation and dissipation and its effect on pile’s shaft and tip resistance) validated with the hypergravity model tests with the results from the conventional neutral plane method also referred as TzQz analysis (ignoring the effect of ue on pile capacity). Major outcomes include 1) TzQzLiq analysis accurately models the response of axially loaded piles in liquefiable soils accounting for all the key mechanisms observed during a shaking event. 2) Most of the pile settlement is co-seismic due to the loss of shaft friction and tip capacity from the increased excess pore pressure in the soil surrounding the pile. 3) While soil settlement from reconsolidation develops large drag loads, the resultant downdrag settlement is minimal, typically less than 2% of the pile diameter. 4) While the neutral plane method (which ignores the effect of excess pore pressures) predicts a downdrag settlement comparable to that of the TzQzLiq analysis, it overpredicts drag load and cannot predict co-seismic settlement. 5) A displacement-based approach using TzQzLiq analysis evaluating the performance of the pile (i.e., the pile settlement and the maximum load) should be used for designing piles.

Performance of Structurally Deficient Blended RC Beams with Fly Ash 🧱⚙️ 📚 Aliker Elizah, Utkrista Pokharel, and P Poluraju have explored the flexural behavior of structurally deficient Reinforced Concrete (RC) beams using fly ash as a partial cement replacement. This research provides crucial insights into improving the durability and strength of RC beams, especially those weakened due to old age or material deterioration. 🔧🌍 🔬 Key Findings: - Structural Deficiencies & Fly Ash: The study focused on RC beams with different steel reinforcement percentages (100%, 70%, and 50%) and varying fly ash content (0%, 20%, and 30%). The research revealed that **incorporating fly ash** significantly enhances the flexural performance of structurally deficient beams. 🏗️💪 - Improved Flexural Performance: Beams with 20% fly ash showed the best performance, demonstrating better crack resistance and higher load-bearing capacities. 💡💥 - Crack Resistance & Load-Bearing: By adding fly ash, even beams with reduced steel reinforcement showed improved performance, mitigating some negative effects of structural deficiencies. 📊⚙️ - Sustainability in Construction: This research emphasizes the potential benefits of using sustainable materials like fly ash to strengthen RC beams, offering a practical approach to enhancing infrastructure durability. 🌱🔨 🔗 Read the full article to learn more about optimizing RC beam designs for improved performance and sustainability: https://lnkd.in/dUsgiTuk 🌟 Stay informed about innovative construction methods and engineering solutions!

🌍 Excited to share my recent research presentation at the International Conference on Materials, Structures and Environment (ICMSE 2024), organized by NSS College of Engineering, Palakkad in association with ISTE Palakkad Chapter and IE(I) Civil Students Chapter 🎉 In this study, I explored the impact of seismic forces on structures with post-tensioned slabs, particularly in challenging sloping terrains. The optimum tendon layout of post-tensioned (PT) slabs was determined, and the seismic performance of a building with a post-tensioned slab was compared to that of a conventional two-way slab on sloping ground using ETABS. The findings highlight innovative approaches to enhance structural resilience in earthquake-prone areas. A big thank you to everyone who attended and engaged in insightful discussions! Let's continue to push the boundaries of engineering for safer, more resilient structures. 💪✨ #ICMSE2024 #NSSCollegeofEngineering #SeismicEngineering #StructuralResilience #PostTensionedSlabs #Research #Innovationinconstruction
