ICC-ES AC349

Full Name

ICC-ES AC349 – Acceptance Criteria for Segmented Precast Concrete Pile Assemblies

Scope

ICC-ES AC349 provides the standards and evaluation methods for precast concrete piles that are assembled from multiple segments. These piles are used to transfer structural loads from a superstructure to the ground, especially in areas with poor soil conditions. The scope of AC349 includes:
  • Material properties: it specifies the requirements for the materials used in segmented precast concrete pile assemblies, including the concrete mix design, reinforcement materials, and connection details between segments.
  • Design and manufacturing: it outlines the design criteria for the pile segments, considering factors such as axial and lateral load capacity, bending moment resistance, and durability. It also addresses the manufacturing process and quality control measures to ensure consistent product quality.
  • Testing: it details the specific tests required to evaluate the structural performance of the pile assemblies, including axial compression tests, lateral load tests, and bending tests.
  • Evaluation and certification: it outlines the process for evaluating and certifying segmented precast concrete pile assemblies to ensure they comply with the acceptance criteria and can be safely used in construction.
By adhering to ICC-ES AC349, manufacturers can demonstrate that their pile assemblies meet the necessary performance and safety standards. It also provides valuable information to engineers, designers, and contractors for selecting and installing suitable pile systems for various projects.
