It is showed that reinforced concrete using inter-locking spiral can not only reduce the artificial error of hoops, but also reduce using the amount of hoops. It is also demonstrated the reinforced concrete using inter-locking spiral can provide more confinement. The present research of reinforced concrete using inter-locking spiral, is mostly aimed at the squared cross-section. However, the rectangular cross-section and the oval cross-section are used to public construction, is still lacked the data to prove the efficacy. The research compares the confinement of reinforced concrete, which have rectangular and oval cross- section, using inter-locking spiral and traditional hoops in the same design code. By the three tests, compression test, recyclic tests and eccentric tests, it can be discussed the feasibility of inter-locking spiral on two different cross-sections. According to the results of experiments, the performance of reinforced concrete which uses inter-locking spiral is better than the one uses traditional hoops. It is showed that inter-locking spiral use on rectangular cross-section and oval cross-section can provide more confinement effect and be used in the public construction.26953825 bytesapplication/pdfen-US多螺箍螺箍筋圍束軸壓試驗反覆載重撓曲試驗反覆載重剪力試驗偏心試驗inter-locking spiralconfinementscompression testrecyclic testeccentric testthesishttp://ntur.lib.ntu.edu.tw/bitstream/246246/255593/1/ntu-100-R98521224-1.pdf
