The experimental test with earthquake simulator to prove the integrity of structures and equipments such as reactor components against earthquake loading has been often performed. In this paper, the reliability theory is applied to such a test and a reasonable method is proposed on how to plan the test for proving structural reliability. In this method the excitation level is the function of expected reliability given by the test, and the most suitable level is chosen so as to give the maximum expected reliability. The most suitable level is derived for the Weibull and the log-normal as well as the normal distribution of earthquake strength, respectively. It is found that the confidence coefficient should be lowered in such a seismic test. And in planning a seismic proof test, each excitation level should be chosen so as to be able to confirm the design, to prove the structural reliability and to evaluate the structural behavior under the extreme condition.
