| Outline of Final Research Achievements |
In this study, the proposed Modified Park-Wen Model is verified by quasi-static loading test and Sub-Structure Pseudo-Dynamic Simulations with Kobe Earthquake and scaled High-Damping Rubber (HDR) bearings. Seismic response simulation for highway viaduct bridges were conducted. As its numerical model, a simplified Two-Degree-Of-Freedom model is used in Incremental Dynamic Analysis (IDA) to evaluated the Anti-Catastrophe Performance of this kind of structures under Design-Level-exceeded earthquakes, and to cumulate basic data about structural collapsing pattern and their probabilities. Using the fragility curves from result of IDA, though, the collapse probability is low for design level earthquake, most possible collapsing pattern under design exceeded earthquakes is the broken of rubber bearings.
