One-Fifth-Scale and One-Half-Scale Two-Dimensional Seismic Tests

摘要

Uni-axial seismic tests were performed on exp 1 / sub 5 -scale and exp 1 / sub 2 -scale two-dimensional models of the HTGR core consisting of 73 graphite elements in a hexagonal array. Core displacement and velocity, boundary support force, and in-core element force were measured. The test rigs were excited in two directions: across-the-flats of an element and across-the-corners. Results from the two models were compared on a normalized scale basis to check the scaling laws. (ERA citation 04:008275)
