Abstract

Four endurance time acceleration curves (ETACs) with duration of 30 s were generated based on South China Sea design response spectra of the International Organization for Standardization (ISO) by using an improved nonlinear least-square method. In addition, the accuracy and reliability of the procedure were discussed. Under the condition of considering seawater, the dynamic response of the platform under strong earthquakes was contrasted and analyzed based on an incremental dynamic method and an endurance time method (ETM). And the rationality of ETM used to evaluate the platform dynamic response was evaluated. The results show that the improved method reduces the iterative times and greatly improves precision of curves. Compared with the incremental dynamic method, ETM greatly reduces the times of time-history analysis. For ETM, the top displacement, the maximum interstory drift ratio and the base shear of the platform structure can be well predicted. Since ETM has the characteristics of high efficiency in calculation, it provides a new and effective method for dynamic response analysis of jacket platforms.
