SUMMARY:Online Workshop: Soil Nail Walls - Design and Construction
DESCRIPTION:Soil nailing technology is versatile and has been widely used worldwide over the last 3 decades for temporary and permanent excavation support. The design and performance of soil nail walls are intricately linked with their construction procedures.  To avoid adverse performance issues\, design and construction processes for a soil nail wall must be tailored to specific geometry and the environment (conditions) expected over its specified lifetime. This workshop will help gain a better understanding of the design and construction procedures using concepts of limit states that will be indexed to the latest guidelines based on the Load and Resistance Factor Design (LRFD) methodology of the American Association of State Highway Officials (AASHTO) and Federal Highway Administration (FHWA). The contrast between LRFD and the Allowable stress design (ASD) methodologies will also be included. Design and construction (including field testing) aspects of Solid Bar Soil Nails (SBSNs) and Hollow Bar Soil Nails (HBSNs) will be discussed. \nUsing a collaborative and interactive learning approach\, this virtual workshop will help you understand soil nail walls’ design and construction aspects. You will learn newer design approaches based on the LRFD platform\, which is the basis for guidelines for soil nail walls by the American Association of State Highway and Transportation Officials (AASHTO) and the Federal Highway Administration (FHWA). The workshop will help you assimilate the design and construction aspects through active participation by frequent interactions throughout the workshop and real-time expert feedback. The interactions will facilitate a better understanding of the nuances of the newer design principles\, which will help you avoid costly design errors in real-world projects. In between the two live sessions\, attendees will independently work on an application (e.g.\, exercises) or a reflection (e.g.\, reading) assignment. \nSession 1 of 2 \n\nIntroductions\nTerminology\, construction steps\, applications\, and explorations\nLimit states\, load factors\, and resistance factors\nService limit state (wall movements)\nStrength and Extreme Event limit states\nLimit Equilibrium (LE) analysis software tools\nCorrosion Considerations\nFacing (shotcrete)\nReview of Session 1\nInteractive Question and Answer (Q&A) session\nAssignment of classwork\nAdjourn for classwork and break\n\nSession 2 of 2 \n\nRoadmap for Session 2\nReview of classwork assignments\nInformation for plans and specifications\nNail types and construction processes\nGrout and grouting\nNail testing and nail acceptance criteria\nClosure and References\nReview of Session 2 and full workshop\nInteractive Question and Answer (Q&A) session
