Pseudo-Dynamic Test of a Full-Scale CFT/BRB Frame
作者 蔡克銓陳垂欣蕭博謙賴俊雄翁元滔林敏郎
英文摘要
A full-scale concrete filled tube(CFT) column with buckling strained braced(BRB) frame was tested n in October of 2003 to study the seismic performance of such system. This paper focuses on the design and experimental responses of the specimen. Three different types of moment connections, namely through beam, external diaphragm and bolted types, varying from floor to floor have been designed and constructed for the exterior beam-to-column joints. Furthermore, three brace types, including the single-cored, double-cored and all-metal BRBs were installed in the three different stories. The test frame will be loaded using pseudo-dynamic procedures to simulate the responses under ground motions corresponding to earthquake hazards for a high-seismicity site with 50%, 10%, and 2% chance of exceedance in 50 years. Nonlinear dynamic analyses illustrate that the peak story drift is likely to reach 0.025 radian after applying the 2/50 design earthquake on the frame specimen. Further, the experimental responses of the specimen also demonstrate great agreement with the predictions. In addition to the experimental investigations, an internet testing platform entitled Internet-based Simulations for Earthquake Engineering(ISEE), launched in the National Center for Research on Earthquake Engineering as a prototype of Internet-based cooperative structural experimental environment is described. Preliminary experimental results illustrate that CFT/BRBF performed extremely well after the application of design earthquake load effects.
