Attention #geotechnicalengineers, with the #lunareclipse happening in North America today, if you want to repeat the experiment by Eratosthenes, you may need to design and build a circular #deepexcavation. In this case, two #reinforcedconcrete diaphragm wall deep excavations with reinforced concrete rings. The images show the normal wall force and the evolution of the ring forces from a 3D #geotechnical #finiteelementanalysis with DeepEX 2024! This model took me approximately 5 minutes to prepare.

🔔 Model to Download | Masonry Arch Hall Would you like to try out two products using a single example❓ We're excited to introduce a new downloadable model prepared for you by the Dlubal Latam team. This model of a masonry arch hall, serves as an ideal illustration for both Pushover analysis and Masonry design. 🧱 The pushover method is a technique used to assess the stability and behavior of masonry structures, particularly vaulted ones. This method is commonly employed in engineering practice, especially for evaluating older historical buildings, often constructed using masonry. Pushover analysis involves gradually applying horizontal forces to the structure and observing its response, accounting for both elastic and plastic deformation of the material. ℹ Download the model and try out our add-ons in practice. Enhance your projects and boost their stability with Dlubal Software! https://bit.ly/3UVRvce #Dlubal #DlubalSoftware #StructuralAnalysis #MasonryDesign #PushoverAnalysis #MasonryStructures

The more information fed into a takeoff, the more information we get out of it. We identify areas requiring demolition of existing concretes, tarmacs etc from either Topographical survey, our own Drone surveys or even Google Earth to ensure we quantify as much resuable/unusable materials possible. I have seen a number of Earthwork takeoffs also including areas such as woodlands, streams & open spaces all of which do not need to be touched but are mostly always included in volume reports, skewing overall figures. We crop our models to contain only the areas we will effectively be excavating/filling through use of aerial imagery & topographical information. We do not need to strip an area of open space, to then put the exact same amount of topsoil back down with no adjustment in level of the subsoil! Leave it out!

📮I am thrilled to share that my new paper, "Effect of Pile Cap Geometry on Soil Arching Behavior in GRPS Embankments: A Comparative Study," has been published in the Journal of Structural Engineering and Geo-Techniques on June 19, 2024!📮 Link to download the paper : https://lnkd.in/dy7Tv6zn “Geosynthetic-Reinforced Pile-Supported Embankments (GRPS) are widely used in infrastructure projects to improve load distribution and stability over soft ground conditions. They enhance the performance and durability of embankments in road, railway, and bridge construction by integrating geosynthetics and pile foundations. This study investigates the impact of various pile head shapes on the performance of Geosynthetic-Reinforced Pile-Supported Embankments (GRPS), an area not extensively studied previously. Five pile head shapes were analyzed: flat head, partial cone, and semi-spherical shapes of varying sizes. A 3D numerical modeling approach using PLAXIS 3D software was employed, beginning with validation of a case study, followed by examination of the effects of the five pile head shapes on stress reduction ratio, induced vertical stress, and ground surface settlement. Results showed that for circular piles with a flat head, increasing the pile head diameter from 1 meter to 1.5 meters reduced the stress reduction ratio from 0.38 to 0.26, highlighting the role of head size in enhancing soil arching. Additionally, changing the pile head shape from semi-spherical and partial cone to flat decreased the stress reduction ratio from 0.62 and 0.58 to 0.38, underscoring the effectiveness of flat head piles in augmenting soil arching within GRPS systems. Enhanced soil arching also corresponded with reduced ground surface settlement. Therefore, for GRPS projects, piles with larger, flat heads are recommended.” #Geosynthetic #Reinforced_Pile #Supported_Embankments #Soil_arching #geotechnicalengineering #civilinfrastructure #soilmechanics #PLAXIS_3D

💡 Innovation in Geotechnics 💡 We'll share the 3 keys to the mechanical behavior of 3D reinforcement: -Semi-Rigid Mattress -Rigid geocells act as a semi-rigid mattress that distributes vertical forces laterally. -3D Confinement -Lateral movement of soil particles is restricted through hoop tension in cell walls. -Beam Effect -Mattress creates a slab that "bridges" over problematic soil evenly and reduces differential settlements 👉 The result? Vertical stresses on the subgrade are reduced by ~50%. 🤔 But, what sets Neoloy® apart from other geocells? Neoloy® rigid geocells have very high-performance parameters compared to HDPE geocells, thanks to: • High elastic stiffness - to withstand long-term loads over time (> 500 MPa at 60⁰ C) • Greater resistance to permanent deformation - for reliable performance throughout the design lifespan (<2%) • High tensile strength - supports heavy loads (> 19-25 kN/m) 📖 Interested in learning more about how this technology works?

Telescopic Arm Laser Concrete Leveling Machine The telescopic arm laser concrete leveling machine is a cutting-edge device used in construction for achieving perfectly level concrete surfaces. Equipped with a telescopic arm, it can extend to cover larger areas, enhancing efficiency and reducing manual labor. The integrated laser system ensures precise leveling by continuously measuring the surface and guiding the machine to adjust the concrete accordingly. This technology results in smoother, more uniform floors, which are crucial for many industrial and commercial applications. Its use minimizes human error and accelerates the construction process, making it an invaluable tool in modern construction projects where precision and speed are paramount.

💡 There it is: the successful completion of an 8.3 km country road project. Our team conducted feature extraction over the entire length of the road. 🛣 From paint stripes and curbs to road widths and poles, every element was meticulously identified and extracted automatically. Furthermore, we precisely positioned other vertical assets utilizing the client's library, ensuring a seamless integration into the existing infrastructure framework. ℹ The project's crowning achievement was the creation of a detailed Digital Terrain Model (DTM) of the terrain, expertly crafted using Civil 3D. #WeAreArenaCAD #3DLaserScanning #FeatureExtraction #DigitalTerrainModel
