In contrast, due to the difference in the applied (strain-controlled tests) and the induced (stress-controlled tests) strains, the liquefaction resistance curves of T xSS are higher than those of CTX under cyclic strain-controlled test.Īndersen KH (1975) Research project summary repeated loading on clay and interpretation of test results. As anticipated, the outcomes of the cyclic stress-controlled CTX testing results in the form of liquefaction potential curves are usually higher than that of the T xSS testing results. The T xSS numerical results are successfully compared with those obtained experimentally from (1) alternative stress-controlled T xSS, (2) available liquefaction potential curves (CSR- N liq) in the literature, and (3) stress-controlled DSS testing results.
The cyclic T xSS stress-controlled tests are numerically simulated by adopting a coupled energy-based pore water pressure model using the computer code, FLAC. In the current study, a series of CTX testing results performed on reconstituted samples of Baie-Saint-Paul, Ottawa C-109, and Quebec CF6B sands are compared to the corresponding T xSS and DSS results under both stress- and strain-controlled conditions. Therefore, the CTX results should be properly correlated to simulate field conditions. While cyclic triaxial (CTX) tests are widely used in liquefaction studies due to their simplicity, direct simple shear (DSS) tests and their ilk (e.g., the combined triaxial simple shear, T xSS) are more representative of stress conditions produced during an earthquake.
