As part of the second phase of vibrational/earthquake investigations ast the HDR (Heißdampfreaktor) Test Facility high-level shaker tests were performed by using a coastdown shaker to investigate full-scale structural response, soil/structure interaction, and piping and equipment response under strong excitation conditions. The performance of pipe support systems was evaluated in seven different multiple-support pipe hanger configurations, ranging from flexible to stiff systems. The details of the experiment design and test performance have been described previously. Here a brief overview of the tests and highlights of test results are presented as are some preliminary results of the validation of a piping analysis method. Finally, the plans for the upcoming experiments are described.
