This presentation focuses on the mechanical behavior of soft clays investigated through a multi-directional direct simple shear (DSS) apparatus. By simulating relevant offshore loading paths, including variations in principal shear direction and asymmetric cyclic loading, the study systematically analyzes the evolution of strain, stiffness degradation, and structural breakdown in soft clay under complex shear conditions. The test results highlight the potential governing role of loading path in controlling strain accumulation rates and stiffness loss patterns, providing experimental evidence to support the modelling of loading history and directional effects in geotechnical design. Building on this, the presentation briefly introduces supplementary centrifuge model tests conducted to further evaluate the influence of multi-directional loading on shared suction anchor performance. The experiments, carried out in reconstituted kaolin clay using multi-point loading configurations and embedded sensing techniques, aim to explore anchor–soil interaction mechanisms under non-coplanar cyclic loading. Although data analysis is still ongoing, preliminary observations already indicate that loading direction plays a role in determining failure modes.
