Standard Penetration Test (SPT) is the most commonly used field test in any geotechnical investigation campaign. Although SPT provides quite useful information on the nature and type of the subsurface strata, owing to its inherent operating mechanism, SPT incorporates several limitations. During the dynamic impact of the SPT hammer during the testi...

Steel corrosion is a fundamental parameter to consider in assessing the design life of reinforced concrete structures, and in arid environments, the suppression of steel corrosion factors positiv ely to extend the design life of bridge elements. A thirty nine year old post tensioned reinforced concrete bridge in Riyadh was selected for installation...

Building Codes and best practice require load testing of embedded structural foundation elements to validate design and construction execution quality. This requirement is particularly challenging when associated with ground improvement schemes relying on granular reinforcing/stone columns. Stone columns present an economic solution for improving t...

The introduction of new and more reliable tools for testing shallow and deep foundations has always been intrinsic to the advancement of geotechnical engineering practice. This thesis aims to introduce a novel testing methodology for conducting quasistatic load tests aimed at quantifying the load-displacement response of shallow foundations at a gi...

Stone columns are an economic solution for improving the bearing capacity of shallow foundations on soft soils. A novel impulse load test was developed and used to quantify the load-displacement response of shallow foundations on stone columns at a clay site. The testing methodology used is the rapid plate load tester. Static and dynamic tests were...

Ideas for testing shallow and deep foundations have always been intrinsic to the development of geotechnical engineering practice. This paper aims to introduce a novel testing methodology for conducting quasi-static load tests aimed at quantifying the load-displacement response of shallow foundations at a given site. This testing methodology will b...
