Constructability-based LRFD for Geotechnical Engineering Features – Deep Foundations – Drilled Shafts

Posted by on Jan 30, 2014 in Webinars | 2 comments

Since January 2009, ASCE has offered a webinar series that addresses practical implementation of Load and Resistance Factor Design (LRFD) for geotechnical features. That series, developed by Jerry A. DiMaggio and Naresh C. Samtani, includes 13 webinars that address various geotechnical features such as driven piles, drilled shafts, micropiles, shallow foundations, and a variety of fill and cut walls. The primary goal of the 13-part webinar series was to address design...

Deep Foundations – Lateral Analysis

Posted by on May 3, 2012 in Webinars | 4 comments

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...

LRFD for Retaining Walls – Fill Walls

Posted by on Sep 12, 2011 in Webinars | 0 comments

This webinar includes discussion on the terminology and types of fill walls, lateral earth pressure theories for fill walls, permanent and transient surcharge loads, applicable load factors, use of minimum and maximum load factors for permanent loads, identification of limit states and resistance factors, pressure surfaces for geotechnical and structural analysis, and consideration of extreme event limit states such as seismic events. This part of the webinar series...
