The near-fault effect on buildings and infrastructures is a significant issue for the safety of human life and property in Taiwan, because there are numerous active faults in the island. It is well known that near-fault earthquakes possess special characteristics of large displacement and high velocity. However, it is difficult to reproduce such near-fault earthquake records using the existing test facilities of the National Centre for Research on Earthquake Engineering (NCREE), thus limiting experimental studies on the near-fault effect. Furthermore, many buildings were severely damaged in the Meinong earthquake in 2016. Among them, some mid-to-high-rise buildings were severely damaged or collapsed and resulted in numerous casualties. In recent years, an increasing number of residential or commercial buildings have been constructed. Thus, the casualty risk caused by the collapse of mid-to-high-rise buildings should not be underestimated, and developing methods of seismic assessment for mid-to-high-rise buildings to identify those with high collapse risk is a critical issue. The NCREE established at the Tainan Laboratory a highperformance six-degree-of-freedom seismic simulation testing system that can simulate near-fault motions. Since the completion of this facility, the NCREE has been providing improved seismic experimental services to government agencies, academia, and industries, which is beneficial to improving public safety during earthquake disasters. This study focuses on the experimental results of collapse tests conducted on the new shaking table at the Tainan Laboratory. The test results are compared with the results of the proposed seismic assessment method. This study can offer abundant information on reinforced concrete (RC) frame collapse behavior and help researchers upgrade existing analytical models to improve the prediction of seismic behavior of RC buildings, as well as enhance economic improvement. |
