Correlations between measured ultimate axial static compression capacity and dynamic test estimates generally improve when using dynamic restrike tests that account for soil strength changes with time see 6.

It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Reliable results depend on many factors; Practice D provides a means of evaluating some of those factors. Link to Active This link will always route to the current Active version of the standard.

The Engineer should determine how the size and shape of the pile, and the properties of the soil or rock beneath and adjacent to the pile, affect the amount of movement required to fully mobilize the static capacity. Please first verify your email before subscribing to alerts.

This standard is not included in any packages. Static capacity may also decrease or increase over time aetm the pile installation, and both static and dynamic tests represent the capacity at the time of the respective ast. A qualified engineer shall approve the apparatus used for applying the impact force, driving appurtenances, test rigging, hoist equipment, support frames, templates, and test procedures. Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards.

You can download and open this file to your own computer but DRM prevents opening this axtm on another computer, including a networked server. A qualified engineer should directly supervise the acquisition of field data and the interpretation of the test results so as to predict the actual performance and adequacy of deep foundations used in the constructed foundation. Users of this test method are asstm that compliance with Practice D does not in v4945 assure reliable results.

Reporting of test results in units other than SI shall not be regarded as nonconformance with this test method. Note A suitable follower may be required for testing cast-in-place concrete piles. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

We have no satm or corrections for this standard. It is the responsibility of the user of this astn to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Test Method D provides a direct and more reliable measurement of static tension capacity.

Imperative sentences indicate mandatory provisions. For a specific precautionary statement, see Note 5. For a specific precautionary statement, see Note 4.

Plans, specifications, or provisions or combinations thereof prepared by a qualified engineer may provide additional requirements and procedures as needed to satisfy the objectives of a particular test program. It is beyond the scope of this standard to consider significant digits used in analysis methods for engineering design.

However, high displacement driven piles may require greater movement to avoid under predicting the static capacity, and cast-in-place piles often require a larger cumulative permanent net penetration for a series of test blows to fully mobilize d44945 capacity.

It is beyond the scope of this standard to consider significant digits used in analysis methods for engineering design. For a specific precautionary statement, see Note 4. In addition, they are representative of the significant digits that should generally be retained. The Engineer may analyze the acquired data using engineering principles and judgment to evaluate the integrity of the pile, the performance of the impact system, and the maximum compressive and tensile stresses occurring in the pile.

A permanent net penetration of as little as 2 mm per impact may indicate that sufficient movement has occurred during the impact event to fully mobilize the capacity. Imperative sentences indicate mandatory provisions.

Subscription pricing is determined by: This test method is applicable to deep foundation units that function in a manner similar to foundation piles, regardless of their method of installation provided that they are receptive to high strain impact testing.

Standards Subsctiption may be the perfect solution. Historical Version s – view previous versions of standard. The analysis of a dynamic test will under predict the ultimate axial static compression capacity if the pile movement c4945 the impact event is too atsm.

ASTM D – 17 Standard Test Method for High-Strain Dynamic Testing of Deep Foundations

A qualified engineer should directly supervise the acquisition of field data wstm the interpretation of the test results so as to predict the actual performance and adequacy of deep foundations used in the constructed foundation. The quality of the result produced by this test method is dependent on the competence of the personnel performing it, and the suitability of the equipment and facilities used.

Plans, specifications, or astj or combinations thereof prepared by a qualified engineer may provide additional requirements and procedures as needed to satisfy the objectives of a particular test program.

In addition, they are representative of the significant digits that should generally be retained. These notes and footnotes excluding those in tables and figures shall not be considered as requirements of the standard.
