This webinar offering concentrates on lateral analysis of deep foundations. Deep foundations are often used for structures which experience large lateral loads for which shallow foundations are not feasible due to large overturning moments and resultant load eccentricities. The LRFD platform offers a rational framework for performing lateral analysis of deep foundations. The webinar will be primarily based on the 5th Edition(2010) of LRFD Bridge Design Specifications Developed by the American Transportation...read more
This webinar includes discussion on the terminology and construction of drilled shafts, identification of limit states and resistance factors, development and use of axial resistance charts, concept of mobilized resistance, group efficiency factors for evaluation of axial resistance of shafts in groups, p-multipliers for evaluation of lateral resistance of shafts in groups, redundancy, evaluation of settlement ....read more
This webinar presents fundamentals of LRFD. It presents an overview of civil engineering design platforms (ASD, LFD and LRFD) including benefits and limitations and discussed the concept of safety using deterministic and probabilistic concepts. The contrast of reliability index with safety factor...read more
This example problem presents a detailed solution for a typical cast-in-place (CIP) wall used by the Arizona Department of Transportation (ADOT). A sloping backfill configuration is assumed. The solution uses ADOT policies to demonstrate the application of LRFD principles in analyzing the external stability limit states that include...read more
This example problem presents a detailed solution for a typical cast-in-place (CIP) wall used by the Arizona Department of Transportation (ADOT). A level backfill configuration with a traffic barrier and live load surcharge is assumed. The solution uses ADOT policies to demonstrate the application...read more
