static pile load test
a failure load from which the engineer may determine the ultimate axial static tensile load capacity of the pile(s). Tests that achieve a failure load may help the designer improve the efficiency of the foundation by reducing the piling length, quantity, or size. 4.3 If deemed impractical to apply axial test loads to an
ASTM D-1143, Standard Test Method for Piles Under Static Axial Compressive Load, latest revision, should be used. This method is applicable to all types of deep foundations that function in a manner similar to piles regardless of their method of installation. It does
1.2 This standard provides minimum requirements for testing deep foundations under bi-directional static axial compressive load. Plans, specifications, and/or provisions prepared by a qualified engineer may provide additional requirements and procedures as needed to satisfy the objectives of a particular test program. 4.3 The engineer and other interested parties may analyze the results of a bi-directional axial compressive load test to estimate the load versus movement behavior and the pile capacity that would be measured during axial static compressive or tensile loading applied at the pile top (see Notes 1-3).Factors that may affect the pile response to axial static loading .test load. The jack reacts against the beam above, which loads the test pile in compression and the reaction piles in tension. The load is being measured using a load cell (note data cable) and the settlement is being measured using linear displacement transducers and reference beams. Traditionally, engineers measured theASTM D1143 Full Name. ASTM D1143 – Standard Test Methods for Deep Foundation Elements Under Static Axial Compressive Load. Scope. ASTM D1143 outlines procedures for determining the axial compressive load-carrying capacity of deep foundation elements, such as piles and caissons. This standard is crucial for evaluating the performance and suitability of these .
5.2 If feasible and without exceeding the safe structural load on the element or element cap (hereinafter unless otherwise indicated, “element” and “element group” are interchangeable as appropriate), the maximum load applied should reach a failure load from which the foundation engineer may determine the axial static tensile load capacity of the . The static axial compressive load test was performed according to the American Standard Test Method, ASTM D1143/ D1143-07 [], in which the dead load weight (Kentledge) system was applied using a hydraulic jack acting against a reaction beam.A schematic of the test is shown in Fig. 2a. The maintained vertical compression load test is .and the pile design to be modified. Three types of loading procedures for a static load test are: 1. The Quick Load Test, 2. The Incremental Static Load Test, and . 3. The Constant Rate of Penetration Test. The Contractor must engage the services of aProfessional Engineer licensed and registered in New York State, experienced in all aspects of . 3.2.3 bi-directional axial compressive load test, n an axial compressive load test performed on a deep foundation element by pressurizing an embedded jack assembly (see deÞnition below), so that the foundation section above the jack assembly moves upwards and the foundation section below the jack
Static Pile Load Testing exceeds the standards Procedure A: Quick Test, for static load testing in compression, and ASTM D3689 for static load testing in tension. Both the compression and tension load tests each take approximately 4 to 8 hours to complete. The Foundation Testing Branch has four static axial pile load test systems of varying
The arrangement for an axial compression test is generally done using either a dead load platform, or a hydraulic jack with reaction (or anchor) piles. The hydraulic jack with . Under Static Axial Compressive Load (Dl 143),” Annual Book of . 1.1 The test methods described in this standard measure the axial deflection of a vertical or inclined deep foundation when loaded in static axial compression. These methods apply to all deep foundations, referred to herein as piles, that function in a manner similar to driven piles or cast-in-place piles, regardless of their method of installation, and may be used for . 3 Static Axial Compression Load Test. 3.1 General. Static axial load test conducted under ASTM D1143-07 re-approved 2013. The main purpose of the test is to check pile performance (capacity and settlement) under axial compression load test. The test can be done by two method, first is kentledge method where the dead load arranges above the .
It is performed using a reaction method. The test procedure involves applying an axial load to the top of the test pile with one or more hydraulic jacks. The reaction force is transferred to the anchor piles that go into tension in the case .
