Abstract_English:\r\rA \rt\rension leg platform (TLP) is prone to progressively capsize under tendon damage. To evaluate the structural capability to resist progressive failure, that is, robustness, approaches for robustness evaluation of the TLP under tendon damage, as well as the response and structural performance of the TLP, were investigated. The response and structural performance of TLP under tendon damage is analyzed through the model built in the hydrodynamic calculation software AQWA. Quantitative robustness evaluation indices are proposed based on three categories, namely, structural attribute, structural behavior, and motion performance. A system of deterministic robustness index is established using the entropy method to weigh each index. In addition, a reasonable robustness evaluation process is set up according to the system proposed. The robustness of the TLP under different tendon damage positions in regular wave is also evaluated to verify the usability and reliability of the approaches proposed. Results show that damaged tendons under one column are worst, damaged tendons under diagonal columns are relatively optimal, and damaged tendons under one pontoon are similar. Meanwhile, the down-wave pontoon is slightly worse and the side-wave pontoon is slightly better.\r\r
