CiteSeerX — A comparison of static and dynamic pile test

dynamic and static tests were performed on a 40 m long, 510 mm square, prestressed, precast concrete pile, instrumented with strain gages and telltales. The objective of the tests was to determine the maximum design load considering capacity and settlement. The soils consisted of about 40 m of estuarine deposits overlying siltstone bedrock.

Static and Dynamic Load Tests of Shaft and Base Grouted

This paper examines shaft and base grouted concrete piles by conducting vertical static load tests (SLTs) and dynamic load tests. Three concrete piles with shaft and base grouting, with base grouting only, and without grouting techniques were selected, and compressive SLTs were conducted. Two piles with grouting were also assessed with dynamic load tests.

Static Load Test. Like the dynamic load test, a Static Load test can be done to evaluate the bearing capacity of the pile. In the Static Load Test, the test load will be applied by hydraulic jacking against Kent ledge (concrete blocks) with the load being measured by calibrated and certified pressure gauges on the selected pile.

PSEUDO-STATIC CYCLIC, SNAP BACK AND SHAKE TABLE

Unbonded post-tensioned precast concrete wall systems have been subject to numerous pseudo-static lateral load tests and extensive numerical modelling to simulate the response of the systems to earthquake excitation [4-7]. However, only a limited number of experiments have been conducted to investigate the dynamic response of UPT wall systems [4].

Taking Precast Concrete to the Limit

In CIMR, precast concrete bridge beams 50 feet (15 meters) in length can be tested under both static and dynamic loading up to 1 million pounds of force. Doubling the service life of America’s bridge infrastructure would be an outcome of tremendous value to both state and federal transportation agencies and to U.S. taxpayers.

Field and Numerical Study for Deteriorating Precast

Two deteriorating DT bridges in South Dakota, both over 30-years old, were field tested with a static and dynamic load. From the recorded strain values, the liveload distribution factors (LLDFs) and dynamic load allowance (IM) factors were calculated. The AASHTO LRFD and AASHTO Standard Specifications were compared with the field LLDFs and IMs.
