SUMMARY:Online Workshop on Deep Foundations – Lateral Analysis and Considerations for Induced Ground Deformations: Day 2 of 2
DESCRIPTION:Deep foundations are designed to transfer load through unsuitable subsurface layers to suitable bearing strata. One of the key advantages of deep foundations is their ability to withstand significant lateral loads. When deep foundations are installed through a soil deposit undergoing consolidation\, the resulting relative downward movement of the soil around piles induces “downdrag” forces on the piles. If embankments are placed adjacent to deep foundations\, as in the case of bridge abutments\, “lateral squeeze” effects can induce significant unbalanced lateral forces on deep foundations. In the case of loose collapse-susceptible soils\, the moisture-induced soil collapse can have a significant lateral effect on deep foundations. Seismic events can generate lateral spread and liquefaction related ground deformations. Adjacent excavations can induce differential lateral forces on deep foundations. This workshop presents the lateral analysis of deep foundations and methods to evaluate various induced ground deformations in deep foundation designs. The presentation will be based on latest (2020) version of the Bridge Design Specifications (BDS) based on the Load and Resistance Factor Design (LRFD) platform of the American Association of State Highway and Transportation Officials which is a key component of Federal Highway Administration (FHWA) guidelines for deep foundations. Information from AASHTO’s latest (2020) guide specification for Service life design will also be presented. \nUsing a collaborative and interactive learning approach\, this virtual workshop will help you understand: (a) principles of lateral analysis of deep foundations\, and (b) the types and effects of induced ground deformations on deep foundations. The workshop will help you assimilate the crucial considerations regarding these topics 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 various design procedures for deep foundations which would 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. \nDAY 1 – Thursday\,  November 17\, 2022 \n\nLoads and limit states\nSoil-structure interaction model\nStructural and geotechnical elements\nExample problem\nEquivalent cantilever model\nSteps for lateral load analysis\nExtreme Events\nSpecial considerations\nReview of Day 1\nInteractive Question and Answer (Q&A) session\nAssignment of homework\nAdjourn\n\nDAY 2 – Monday\,  November 21\, 2022 \n\nRoadmap for Day 2\nReview of homework\nGeneral concepts and terminology for induced ground deformations\nDowndrag and drag load\nMoisture-induced collapse of soils\nLateral squeeze\nLateral spread\nExcavation-induced effects\nSummary and comments\nClosure and references\nReview of Day 2 and full workshop\nInteractive Question and Answer (Q&A) session\nAdjourn

SUMMARY:Online Workshop on Drilled Shafts in Soils – Design and Construction: Day 2 of 2
DESCRIPTION:Drilled shaft foundations in soils are often a technically sound and cost-effective foundation choice where a deep foundation solution is appropriate based on-site conditions\, applied loads and project schedule and performance requirements. To avoid adverse performance issues\, design of drilled shafts must be performed based on consideration of site-specific geologic conditions and construction methods. To help comprehend these crucial considerations for successful implementation of drilled shafts in soils\, the thrust of the discussions in this workshop is to establish a good understanding of the design procedures for drilled shafts and how construction procedures can affect the design of drilled shafts. Various design considerations and methods will be discussed. Different construction methods such as dry\, cased\, and wet will be discussed. The evaluation of structural integrity of constructed shafts using methods such as cross-hole sonic logging (CSL)\, gamma-gamma logging (GGL) and thermal integrity profiling (TIP) will also be presented. The presentation will be based on latest (2020) version of the Bridge Design Specifications (BDS) based on the Load and Resistance Factor Design (LRFD) platform of the American Association of State Highway and Transportation Officials which is a key component of Federal Highway Administration (FHWA) guidelines for drilled shafts.

SUMMARY:Online Workshop on Compaction of Soils and Engineering Properties of Compacted Soils - Day 2 of 2
DESCRIPTION:In the construction of highway embankments\, earth dams\, retaining walls\, structural foundations\, and many other facilities\, loose soils must be compacted to increase their densities.  The principal objectives in compacting soil are normally to create fill of high strength and low compressibility\, and\, in the case of water-retaining fill\, of low permeability. The ultimate goal is to construct safe earth structures that can provide the desired serviceability over their design lifetimes and minimize long-term maintenance. This workshop discusses the conventional (e.g.\, Proctor) methods of compaction and alternative methods of compaction based on soil air voids and shear strength (SAV&S) principles. It evaluates applicability of compaction procedures for various soil landforms (e.g.\, residual vs transported) soils. It also discusses implications of laboratory tests on field compaction specifications and properties of compacted soils such as shear strength\, volume change\, and permeability. It evaluates the concept of cohesion component of shear strength in compacted soils. \nUsing a collaborative and interactive learning approach\, this virtual workshop will help learners understand challenges associated with specification and construction of safe and serviceable compacted soil structures that will also help long-term maintenance needs. Learn new concepts of soil compaction that builds upon your prior knowledge and through active participation you will integrate the new knowledge into your understanding. You will also generate new ideas through brainstorming and discussion and develop a better understanding of the practical methods and processes of soil compaction\, learn about real-world problems that your peers encounter on projects\, and solutions they have implemented\, and receive real-time expert feedback. In between the two live sessions\, attendees will independently work on an application (e.g.\, exercises) or a reflection (e.g.\, reading) assignment. \nDAY 1 (May 19\, 2022) \n\nIntroductions\nTerminology and Basics of Compaction\nEffect of Unit Weight\, Voids\, and Fabric/Structure\nField Compaction Procedures\nRelative Density and Relative Compaction\nPractical Issues and SAV&S Field Control Method\nChoice of Field Compaction Control Method\nReview of Day 1\nInteractive Question and Answer (Q&A) session\nAssignment of homework\nAdjourn\n\nDAY 2 (May 23\, 2022) \n\nReview of homework assignment\nRecap of Day 1\nRoadmap for Day 2\nShear Strength Characteristics of Compacted Soils\nVolume Change Characteristics of Compacted Soils\nPermeability Characteristics of Compacted Soils\nProof-rolling\nReview of Day 2 and full workshop\nInteractive Question and Answer (Q&A) session\n\nAdjourn

SUMMARY:Online Workshop on Mechanically Stabilized Earth (MSE) Walls – Understanding Fill Properties and Good Practices for Details - Day 2 of 2
DESCRIPTION:Mechanically Stabilized Earth (MSE) walls are used extensively for grade-separation fill structures in many applications\, e.g.\, highways\, railways\, marine\, commercial\, etc. To avoid adverse performance issues\, and to ensure safe and serviceable MSE walls\, the fills and component details must be tailored to specific geometry and the environment (conditions) expected over its specified lifetime. To help comprehend these crucial considerations for successful implementation of MSE wall projects\, the thrust of the discussions in this workshop is to: (a) establish a baseline for understanding the design and construction considerations associated with the use of geomaterials for MSE wall fills\, and (b) emphasize attention to details of various components. The presentation will also include information on the new MSE-LASR technology that permits consideration of Local Available Sustainable Resources (LASR)\, i.e.\, non-select or marginal fills. The fill criteria by the National Concrete Masonry Association (NCMA) for segmental retaining walls will also be contrasted with MSE and MSE-LASR fill criteria. \nUsing a collaborative and interactive learning approach\, this virtual workshop will help you understand: (a) the fill properties and the underlying reasons for specification values for fills\, and (b) good practices for details. The workshop will help you assimilate these crucial considerations 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 fill properties and details which would help you avoid costly design and construction errors in real-world projects.

SUMMARY:Soil Nail Walls - Design and Construction: Day 2
DESCRIPTION:Soil nailing technology is very 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 is intricately linked with its 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). 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.

SUMMARY:Soil Nail Walls - Design and Construction: Day 1
DESCRIPTION:Soil nailing technology is very 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 is intricately linked with its 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). 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.

SUMMARY:Mechanically Stabilized Earth (MSE) Walls – Limit State Based Design Principles [Day 2]
DESCRIPTION:Mechanically Stabilized Earth (MSE) walls are used extensively for grade-separation fill structures in many applications\, e.g.\, highways\, railways\, marine\, commercial\, etc. To avoid adverse performance issues\, design processes for an MSE wall must be tailored to specific geometry and the environment (conditions) expected over its specified lifetime. This workshop is geared towards development of a better understanding of design procedures using principles of limit states to ensure safe and serviceable MSE wall structures over specified lifetimes. More specifically\, this workshop is based on the Load and Resistance Factor Design (LRFD) methodology that is a North American version of the broader Limit State Design (LSD) approach. The design principles will be explained using wall geometries with level and sloped backfill configurations. The topic of complex geometries will be introduced. The presentation ends with a brief introduction to the design philosophy for the new MSE-LASR technology that permits consideration of Local Available Sustainable Resources (LASR)\, i.e.\, non-select or marginal fills. \nPolicies and System Requirements for Viewing this Course \nINSTRUCTOR:\nNaresh Samtani\, PH.D.\, P.E.\, D.GE\, F.ASCE \nREGISTER:\nClick here to register for this online event
