TY - JOUR PY - 2023// TI - Moving safety evaluation of high-speed train on post-earthquake bridge utilizing real-time hybrid simulation JO - Journal of earthquake engineering A1 - Guo, Wei A1 - Wang, Yang A1 - Zeng, Chen A1 - Wang, Tao A1 - Gu, Quan A1 - Zhou, Huimeng A1 - Zhou, Lingyu A1 - Hou, Wenqi SP - 284 EP - 313 VL - 27 IS - 2 N2 - This study aimed to provide an experimental evaluation method for train's moving safety on a post-earthquake bridge. First, an improved real-time hybrid simulation (RTHS) framework was constructed, based on utilizing the moving load superposition algorithm to solve the train-track-bridge interaction (TTBI) problem. An RTHS test was then conducted for the TTBI problem. The train model was tested using a shake table and was dynamically linked to the numerical substructure. A post-earthquake seven-span high-speed railway simply supported bridge was studied, in which earthquake-induced damage, such as stiffness reductions, residual displacements of piers, girder gap expansions, and pier settlements were all tested.
