碩士 === 國立成功大學 === 建築學系 === 107 === The objectives of this research are to understand the seismic performance of hollow concrete brick panels attached to steel frames and to review the current construction methods. To accomplish these, two specimens with and without a central opening were subjected to in-plane reversed cyclic displacements and constant vertical loading. The results shown that the panel endured lateral forces at a small drift ratio, contributing strength to the specimen. After diagonal cracks were formed, brick spalling started to occur and the interfaces between columns and the panel completely cracked open. When the steel frame started to detach from the panel, it began to developed its strength and ductility. Moreover, the upper and lower halves of the cavity still caused the yielding place of the columns to transfer from ends to the body. Because of the close connection between the columns and the panel, both panels failed at a small drift ratio 0.2%, which does not meets the nonstructural performance criterion in ASCE 41-13.
