Q Mhaiskar, S. Link to Active This link will always route to the current Active version of the standard. The initial part of the load-settlement curves Figure 6: This will be achieved by taking four case studies, conducted in Red Sea State in eastern Sudan.

The load-settlement behaviors for dynamic and static load tests d4945–00 compared for the three case studies of the residential tower buildings complex project. Q Figure 3: Enter the email address you signed up with and we’ll email you a reset link. The measured force at the pile top is separated into components upward and d4945-000.

This paper has been focused on this type of pile loading test. Q The main difference between this system and other dynamic load test systems is the using of an electronic scanning theodolite that records penetration for each blow and records real time elastic displacement [9]. This is Portsudan city, which is located in western coast of the Red Sea in eastern Sudan [11].

ASTM D – 00 Standard Test Method for High-Strain Dynamic Testing of Piles

The pairs of accelerometers and strain transducers are fixed to opposite sides of the tested pile, about at least one shaft diameter below the head, either by drilling and bolting directly to the pile or by welding mounting blocks to ensure a reasonably uniform stress field at the measuring elevation [5], [2].

The dynamic or total reaction, Rdy is calculated for each hammer blow and plotted versus cumulative penetration for the whole set of blows. 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. L Load KN 0 0 0. Help Center Find new research papers in: The formation at this area is predominantly coralline deposits consisting of completely to slightly weathered coral reef limestone that contains marine shells and fossils.

Svinkin analyzed a distinctive case history presented by Briaud et al. D — 00″ 5- Richard T. Three projects are residential tower buildings representing a part of the residential tower buildings complex of Red Sea state.

This is very clear especially in the results of the pile of tower 1 project.

Active view current version of standard. Four case studies of dynamic and static pile loading tests conducted in the eastern of Sudan have been presented.

Referenced Documents purchase separately The documents listed below are referenced within the d945-00 standard but are not provided as part of the standard.

It can be concluded that the dynamic load pile test can be used for predicting pile capacity and pile integrity under proper care and it should 4d945-00 calibrated by at least one static test. The comparisons of load-settlement behaviors for dynamic and static load tests, shown d494-500 Figure 5Figure 6 and Figure 7indicate that the predicted settlement from dynamic and the measured aatm from static are generally consistent to a reasonable extent as reflected by the results of towers 7 and 8.

Solanki, Associte Professor, and Y. Q Tower 7 The load should be applied axially on the pile. The dynamic load pile test, which is a simple quality control test offering a considerable savings of time and cost and requires less space, can be used for predicting pile capacity and pile integrity under proper care and it should be calibrated by at least one static test.

It consists of estimating soil resistance and its distribution from force and velocity measurements obtained near the top of a foundation impacted by a hammer or drop weight. Essential preparations should be made before the test is carried out in the field.

The cap must be cylindrical, smooth, well-reinforced and of good quality concrete. The two test results are consistent to a good extent.

A series of hammer blows are made with the hammer drop height progressively increased and decreased [8]. The modern change, which is considered as one of the significant beneficial changes that have been made to the system since the last Irish survey in is the introduction of theodolite to measure the pile displacement during the impact [6], [7].

For a specific precautionary statement, see Note 5. A pile cap, as an extension to the shaft head with the same diameter as the shaftshould be constructed. For mandrel driven piles, the mandrel may be instrumented in a similar way to a driven pile provided that the mandrel is constructed of a single member with no joints.

Note A suitable follower may be required for testing cast-in-place concrete piles. 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.

The side of the cap is instrumented with two strain gauges, two accelerometers and electronic theodolite target.
