It is beyond the scope of this standard to consider significant digits used in analysis methods for engineering design. Please first verify your email before subscribing to alerts. Reporting of test results in units other than SI shall not be regarded as nonconformance with this test method.
Additional transducers embedded near the pile toe may also help improve tension capacity estimates. Static capacity may also decrease or increase over time after the pile installation, and both static and dynamic tests represent the capacity at the time of the respective test. 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.
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. Imperative sentences indicate mandatory provisions.

For mandrel driven piles, the mandrel may be instrumented in a similar c4945 to a driven pile aztm that the mandrel is constructed of a single member with no joints.
Factors that may affect the axial static capacity estimated from dynamic tests include, but are not limited to the:. As the voice of the U. We have no amendments or corrections for this standard. Although interpretation of the dynamic test analysis may provide an estimate of the pile’s tension uplift capacity, users of this standard are cautioned to interpret conservatively the side resistance estimated from analysis of a single dynamic adtm location, and to avoid tension capacity estimates altogether for piles with less than 10 m embedded length.
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 the capacity. 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 d4495 program.

ASTM D – 00 Standard Test Method for High-Strain Dynamic Testing of Piles
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 v4945 used in the constructed foundation.
Need more than one copy? Force and velocity are typically derived from measured strain and acceleration.
In addition, they are representative of the significant digits that should generally be retained. 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.

Proceed to Checkout Continue Shopping. This standard is also available to be included in Standards Subscriptions. 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. Dd4945 other units of measurement are included in this standard.
Users of this test method are cautioned that compliance with Practice D does not in itself assure reliable results. 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.
