ACIP and DD
Committee Initiatives
Contents
Completed Committee Project Fund Awards
ACIP Pile Installation, Installation Monitoring, Full-scale Load Testing, and Extraction Program
Instrumented and monitored full scale compression, tension and lateral load tests on ACIP Piles.
$30,000
Assessing International building code load test criteria
Independent review and analysis of available pile design information, load testing results, and associated pile construction costs to quantify the level of over-conservatism that results from inappropriate acceptance criteria commonly included in building codes.
$17,000
Investigation of Development of Lateral Stresses During Installation of Drilled Displacement Piling
Monitoring installation of small scale DD piles to assess radial effect and extent of lateral stresses and displacements.
$26,100
Low Headroom ACIP Installation
Supplement to DFI ACIP Piles Manual
Stability of Large Diameter ACIP Piles
Completed Research Projects
- Review and analysis of available pile design information, load testing results and associated pile construction costs to assess validity of acceptance criteria in the building codes
- Instrumented and monitored full scale compression, tension, and lateral load tests on ACIP Piles
- Axial Load Capacity Predictions of Drilled Displacement Piles With SPT- and CPT-based Direct Methods
Ongoing Research
Lateral Stresses During DD Pile Installation
Monitoring installation of small-scale drilled displacement piles to assess radial effect and extent of lateral stresses and displacements.
Evaluation of In Situ ACIP Pile Volume
Conducting thermal integrity profiling on ACIP test piles and analyze to assess in place diameter.
Seismic Performance of Rigid Inclusions
Numerical simulation study of rigid inclusions installed in liquefiable soils to show the effect of various design parameters and demonstrate how coupled use of typical site response and lateral loading analyses that practitioners perform on a daily basis can sufficiently capture the critical aspects of our research findings.
