Reliability Analysis of the HEC-18 Scour Equation and AASHTO Deep Foundation Design Codes
… project studied the reliability of driven pile foundations subjected to scour, gravity loads including dead loads and live loads, and their combinations. The design of the foundation followed the procedures of the AASHTO LRFD Bridge Design Specification. The design methods were the HEC-18 pier …

Evaluating soil pressures on a deep foundation element due to liquefaction-induced lateral spreading
The behavior of bridge foundations during earthquakes includes the inertial response of the foundation and superstructure system, and the kinematic forces induced by the lateral spreading ground. Both must be analyzed in practice to design a bridge foundation, or other foundation type, subject to …

Flexural Behavior of Carbon/Epoxy IsoTruss Reinforced-Concrete Beam-Columns
… concrete beam-columns for use in deep foundation pile applications. Four-point bending tests were performed in the laboratory on two instrumented carbon/epoxy IsoTruss® reinforced concrete piles (IRC piles) and two instrumented steel reinforced concrete piles (SRC piles). The piles …

A House For A River Rat
… prevent damage when the river floods, and has a deep foundation to achieve stability on the loose floodplain soil. It has three levels, the first containing the main living areas, the second, a lofted space containing the bed and bath, and the third, a roof terrace. It is for two people, and so …

ANALYSIS OF THE EFFECTS OF HEAVILY LOADED MAT FOUNDATION ON ADJACENT DRILLED SHAFT FOUNDATION
Construction of heavily loaded shallow foundations adjacent to deep foundation is generally avoided in common geotechnical engineering practice to minimize additional loads on deep foundations. However, with the growing trend of urbanization leading to a demand of new construction, it is not always …

Performance of foundations in a rising groundwater environment
… such an increase in pore pressure would have on foundations in overconsolidated clay was investigated. The performance of foundations in stiff clay during a rising ground water event was investigated by means of centrifuge model tests. The model tests included comparisons of the behaviour of …

Dynamic Pile-Soil Interaction in Laterally Spreading Slopes
… is known to be one cause of severe damage to deep foundation systems. However, the dynamic soil-structure interaction between liquefied soil and piles is extremely complex and further work is required to define the appropriate design pressures and to understand the mechanisms at work. This …

Axial load transfer in large scale physical model drilled shaft foundations
Drilled shaft foundations are a widely implemented type of deep foundation used to support heavy loads from superstructures such as buildings and bridges. Uncertainties exist in the axial load transfer behavior of drilled shafts subject to loading and unloading cycles. A better understanding of the …

Novel Application of Nondestructive Testing to Evaluate Anomalous Conditions in Drilled Shafts and the Geologic Materials Underlying Their Excavations
Drilled shafts are deep foundation elements created by excavating cylindrical shafts into the ground and filling them with concrete. Given the types of structures they support, failure to meet their performance criteria can jeopardize public safety and cause severe financial losses. Consequently, …

Thermo-Mechanical Behavior of Energy Piles: Full-Scale Field Testing and Numerical Modeling
Energy piles are deep foundation elements designed to utilize near-surface geothermal energy, while at the same time serve as foundations for buildings. The use of energy piles for geothermal heat exchange has been steadily increasing during the last decade, yet there are still pending questions on …

Dynamic soil modeling in site response and soil-large pile interaction analysis
… the effects of lateral spreading on large pile foundations. Two new soil damping formulations are implemented in non-linear one-dimensional site response analysis for small and large strains. The first formulation introduces an approach to construct a frequency-independent viscous damping matrix …

Seismic Analysis and Response of Highway Bridges with Hybrid Isolation
… demand on critical members such as columns and foundations, but hybrid isolation also reduces superstructure displacements and the corresponding size of abutment movement joints. A key factor, however, to the success of hybrid isolation (where isolators are placed only at the abutments) is the …

Evaluation of Scale Effects in Load-Displacement Response of Drilled Shafts Based on Field Load Tests
… tests are widely accepted practices that provide foundation designers with site-specific information about the nominal resistance of drilled shaft foundations. The application of load testing in drilled shaft foundations provides insight into the load-displacement behavior which can be used to …

Full-Scale Lateral Load Test of a 3x5 Pile Group in Sand
Although it is well established that spacing of piles within a pile group influences the lateral load resistance of that group, additional research is needed to better understand trends for large pile groups (greater than three rows) and for groups in sand. A 15-pile group in a 3x5 configuration …
