Join us today at the opening ceremony of #ASCE Geo-Congress in #vancouver #canada! #geotechnicalengineers know that #slopestability is very important when excavating in slopes. In this real case, a deep excavation with #reinforcedconcrete piles supported with three levels of prestressed ground anchors in our #DeepEX software with a 2D #geotechnical #finiteelementanalysis and a #slopestability analysis in one file. Always consider proper #constructionstaging in your model. Conventional limit-equilibrium analysis was also examined for apparent earth pressures, together with a Winkler based non-linear analysis. The animations show the #structural bending moments of the wall as well as the bending capacity. In other words, a complete #deepexcavation design! Follow Deep Excavation LLC for more!

📮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

𝗔𝗦𝗖𝗘 𝟳: 𝗦𝗲𝗶𝘀𝗺𝗶𝗰 𝗗𝗲𝘀𝗶𝗴𝗻 𝗖𝗮𝘁𝗲𝗴𝗼𝗿𝗶𝗲𝘀 🟩🟨🟥 The seismic design categories (SDCs) according to ASCE 7, which is a standard issued by the American Society of Civil Engineers that provides minimum load requirements for the design of buildings and other structures, are classifications that reflect the likelihood of experiencing earthquake-induced structural damage. The categories range from A to F, with Category A representing structures located in areas with the lowest seismic risk and Category F representing structures in areas with the highest seismic risk. These categories are determined based on factors such as the soil type at the site, the occupancy category of the structure (which reflects the potential risk to human life, health, and welfare should the structure fail), and the seismic design parameters based on the geographic location of the structure. Here's a brief overview of the categories: 🟩 𝗦𝗗𝗖 𝗔: Represents buildings in areas with the least seismic activity. Structures in this category are typically not required to be designed for seismic forces in many cases, as the expected ground motion is very low. 🟨 𝗦𝗗𝗖 𝗕 𝗮𝗻𝗱 𝗖: Represent buildings in areas with low to moderate seismic activity. Buildings in these categories are required to be designed to withstand seismic effects, but the requirements are not as stringent as for the higher categories. There's a differentiation in the level of detailing and design requirements between B and C, with C having more stringent requirements. 🟥 𝗦𝗗𝗖 𝗗, 𝗘, 𝗮𝗻𝗱 𝗙: Represent buildings in areas with moderate to high seismic activity. The design requirements become increasingly stringent from D to F. Buildings in these categories are required to incorporate more detailed seismic design features to ensure life safety in the event of an earthquake. Category D is split into two subcategories, D0 and D1, in some versions of ASCE 7, to address different levels of seismicity within what is broadly considered moderate seismic activity. The categorization into SDCs is crucial for ensuring that buildings are appropriately designed to withstand seismic events based on their geographic location and use. This helps in minimizing the risk of catastrophic failure and maximizes the safety of occupants and assets during an earthquake. #StructuralEngineering #EarthquakeEngineering #Seismic #StructuralDesign #SeismicDesign

Unveiling The benefit of a site survey Site surveys provide accurate, baseline information that becomes the foundation of a project's scope of work and design documentation. Site surveys are inspections of an area where work is proposed, to gather information for a design or an estimate to complete the initial tasks required for an outdoor activity. It can determine a precise location, access, best orientation for the site, and the location of obstacles. Surveyors use their measurements and data to help engineers and architects design structures that are safe and efficient. Accurate land survey data also helps to ensure that construction projects stay within budget and are completed on time. What is included in a survey: (1)Existing buildings (including valuation, measured surveys, structural surveys, structural investigations, condition surveys, and demolition surveys). (2)Geological and geotechnical. (3)Topographical surveys, perhaps including laser scanning, Lidar or photogrammetry. (4) Contamination. So, if you're looking to build a site regardless it is an old home or bear development land, you need a site survey, we can help. Our engineering solutions cater to both residential and commercial construction projects, and we'll make sure that you get the most out of your land. #builder #developers #buyer #seller #land #landowners #propertymanagers #propertyowners #residential #commercial #new #developers #realestate

🗻 Mastering Terrain: The Crucial Role of Topographical Surveys in Construction 🏗️ In the dynamic world of construction, the foundation of every successful project rests upon a comprehensive understanding of the terrain. 🔍 Importance of Topographical Surveys: Topographic surveys are more than just surface observations; they play an important role in risk mitigation and structural resilience. Without thorough surveying, projects risk a multitude of possible challenges: ◾ Reduced risk of design flaws and construction errors. ◾ Precision terrain mapping reduced sensitivity to drainage difficulties. ◾ Minimized environmental impacts like habitat disruption and soil erosion.
