Dataset from flexural, impact, and hydraulic pressure tests on driven energy piles

Area of Science:

• Civil Engineering
• Geotechnical Engineering
• Materials Science

Background:

• Energy piles are increasingly used in sustainable building designs.
• Comprehensive performance data for precast concrete driven energy piles is scarce.
• Existing research often lacks detailed, accessible datasets for validation.

Purpose of the Study:

• To present a publicly accessible dataset from comprehensive tests on precast concrete driven energy piles.
• To detail the structure and processing methods of the collected data.
• To highlight the dataset's value for future research and practical applications in foundation design.

Main Methods:

• Flexural, impact, and hydraulic pressure tests were conducted on seven precast concrete driven energy piles.
• Data acquisition included material properties, pile driving analyzer (PDA) outputs, hydraulic pressure measurements, and bending test results.
• Digital Image Correlation (DIC) was employed for detailed analysis of structural performance.

Main Results:

• A comprehensive dataset covering material properties, impact, hydraulic, and flexural tests is now publicly available via DataverseNO.
• Raw and processed data, including sensor readings and DIC images, are provided for detailed analysis.
• The data captures the structural performance of pile joints under various loading conditions.

Conclusions:

• The dataset serves as a crucial benchmark for the design and validation of structural joints in precast concrete driven energy pile foundations.
• It offers valuable insights for numerical modeling and performance assessment of energy pile systems.
• The open-access nature of the data promotes further research and innovation in geotechnical engineering.
