Youssef's research used a unique database of dynamic loading tests of driven piles installed in the Puget Sound Lowlands. It included over 237 piles from 40 projects and construction sites throughout Puget Sound Lowlands, Seattle and Tacoma. Of these piles, CAPWAP was performed on a subset of over 180 piles. CAPWAP signal matching was performed by independent, specialized professional engineers with experience in dynamic testing in the Puget Sound Lowlands. All dynamic tests were performed by either GRL, Inc. (42 %) or RMDT, Inc. (58 %). All piles were steel closed, open pipe, or H-steel piles, concrete octagonal fully closed piles or concrete cylindrical open piles. For 95 piles, measurements of penetration resistance were recorded for end of driving (EOD) and beginning of restrike (BOR) conditions. The goal of the study was to improve the reliability of axial performance. First, the unit shaft resistances developed from stress wave signal matching to dynamic records of pile installation were used to develop an effective stress-based shaft resistance model. New, statistically unbiased unit shaft resistance models (Beta-coefficients) were proposed for piles driven at End-of-Drive (EOD) and Beginning-of-Restrike (BOR) and for a range of specific soil types and relative densities and consistencies. The accuracy and uncertainty of each model was then quantified and compared. Then, the observed unit shaft resistances and proposed design models were used to characterize the magnitude of time-dependent capacity gain (i.e., setup or relaxation). The study concluded with the quantification of accuracy and uncertainty in dynamic wave equation-based and existing static analysis procedures and calibration of resistance factors for use with load and resistance factor design (LRFD) using Monte Carlo simulations. These resistance factors indicate, in some cases, dramatic improvement in the useable pile capacity at a given reliability owing to the use of a database from a specific region. The results from this work may be immediately applied in practice in the Puget Sound Lowlands.

In addition to specializing in geotechnical engineering, Youssef has a strong background in mathematics and statistics. He studied applied mathematics, topology, numbers theory, numerical analyses, and advanced real and complex analyses. He used programming languages R and C to perform data analyses using Monte Carlo simulations and other statistical computations.
