Rapid Load Testing: A Useful Alternative for Foundation Testing

Presented by Marcel Bielefeld on February 1st, 2024. Of all the foundation load test methods, Static Load Tests are considered the most reliable, but it is a long process, both for the construction of the reaction system and for the test itself. This means that static load tests have a high cost, and in addition the mobilization of the reaction elements often interferes with the site logistics. In the 1960s an alternative to static load tests was developed: the High Strain Dynamic Test, commonly referred to as a Dynamic Load Test. While this test method has advantages in terms of cost and test duration, these advantages are offset by a reduction in the accuracy of the results. In addition, the impact energy that must be applied to mobilize the test load can damage the foundation being tested. In the mid 1980s another alternative load test was developed, right here in Canada: the Rapid Load Test, whereby a load is applied to the foundation under quasi-static conditions. The first application was the so-called StatNamic test, which uses solid fuel to generate a downward force on the foundation. Given environmental and safety regulations in many countries around the world, the (transport of the) fuel for a StatNamic test can be problematic. As a result, alternate rapid load testing devices were developed that do not involve combustion, such as the StatRapid. In this presentation, Marcel Bielefeld will compare these foundation testing methods in more detail and demonstrate that Rapid Load Testing is not only a useful alternative for foundation testing but that, especially for larger foundation elements, this testing method deserves to be considered first.
