What is dynamic pile load test?
Dynamic load testing (or dynamic loading) is a method to assess a pile’s bearing capacity by applying a dynamic load to the pile head (a falling mass) while recording acceleration and strain on the pile head. The procedure is standardized by ASTM D4945-00 Standard Test Method for High Strain Dynamic Testing of Piles.
What is static load and dynamic load?
Static loading refers to the load on an actuator when it is in a fixed or stationary condition. Dynamic load is the load the actuator sees when it is powered and extending or retracting. The dynamic load capacity of an actuator refers to how much the actuator can push or pull.
What is pile dynamic analysis?
Pile dynamic analysis involves attaching sensors directly to the pile. These sensors are read and recorded during the driving and this data is used to ensure the integrity of the pile by monitoring the stresses to which the pile is subjected.
Why dynamic capacity of pile is generally higher than the static capacity?
For the two piles in- cluded in this figure, strain readings in the pile were obtained during the static test using strain gages. The base resistance obtained from the dynamic test is higher than predicted by the static test because of the large temporary compression of the rock during the dynamic test.
What is static pile load test?
Static Load Tests measure the response of a pile under an applied load and are the most accurate method for determining pile capacities. The purpose of such tests is to verify that the load capacity in the constructed pile is greater than the nominal resistance (Compression, Tension, Lateral, etc.) used in the design.
What is meant by dynamic testing?
Dynamic testing (or dynamic analysis) is a term used in software engineering to describe the testing of the dynamic behavior of code. That is, dynamic analysis refers to the examination of the physical response from the system to variables that are not constant and change with time.
What is the difference in static and dynamic?
In general, dynamic means energetic, capable of action and/or change, or forceful, while static means stationary or fixed. In computer terminology, dynamic usually means capable of action and/or change, while static means fixed.
What is dynamic and static load testing?
Static load testing is an in situ type of load testing used in geotechnical investigation to determine the bearing capacity of deep foundations prior to the construction of a building. It differs from the statnamic load test and dynamic load testing in that the pressure applied to the pile is slower.
What is static load test on pile?
Static Load Tests measure the response of a pile under an applied load and are the most accurate method for determining pile capacities. They can determine the ultimate failure load of a foundation pile and determine its capacity to support the load without excessive or continuous displacement.
What is the difference between static and dynamic testing?
Static Testing involves checklist for testing process. Dynamic Testing involves test cases for testing process. It includes walkthroughs, code review, inspection etc. It involves functional and nonfunctional testing.
What is static & dynamic testing?
Static testing is a system of White Box testing where developers verify or check code to find fault. This type of testing is completed without executing the applications that are currently developed. Dynamic Testing is completed by walking the real application with valid entries to verify the expected results.
Is there a comparison between static and dynamic load testing?
In this study a comparison between the static and dynamic load tests results was made to evaluate the ability of the High Strain Dynamic Pile Testing (HSDPT) using SIMBAT method to estimate the static capacity of bored concrete piles. Four case studies conducted in Red Sea state were taken. The two test results are consistent to a good extent.
How many anchor piles are used in static load testing?
A five-pile test group (four anchor piles and one test pile) is used for all static load tests in compression and for most tension tests (Figure 8-1).
How is a pile driving analyzer used in a load test?
Information retrieved by the Pile Driving Analyzer is also used to predict a pile’s static load capacity. The dynamic analysis is performed on production piles as specified in the special provisions and on the test and/or anchor piles used for a Static Load Test if applicable.
How is PDA used in static load testing?
In lieu of doing a static load test, PDA can be used to establish criteria for pile acceptance and to verify design assumptions. It can determine soil resistance, hammer efficiency/performance, and stresses in the pile during driving.
