摘要：

Former investigation on the aseismic test for core-bottom structure in the high temperature engineering test reactor (HTTR) clarified the response of acceleration, strain, impact load etc. Following this investigation the component test of connecting elements between graphite components was carried out to evaluate their fracture load and fracture mode. The stress analysis was also performed to estimate the stress profile by the analytical approach. The seismic design load is also estimated by considering the load concentration factor. In this paper the experimental and analytical results are compared and the structural integrity of these connecting elements is discussed under the severest earthquake condition postulated in the HTTR structural design.
