| 摘要： | Experimental results provided in the related literature are used in the present study to develop a method for estimating the shear strength of circular concrete-filled steel tubes (CFSTs). This study benefits from using the findings of a significant number of experimental specimens with high diversity in terms of experimental details such as geometric dimensions, material specifications, test setups, as well as axial load. Within this method, the shear strength of the CFST member is considered to be the sum of the shear strength of the steel tube and that of the concrete core. The parameters supposed to affect the shear strength of the concrete include confinement factor, shear span ratio, and axial load ratio. A comparison between the results of the proposed method and other analytical ones also reveals that the proposed equation has a generally higher accuracy, and its estimates are in more agreement with experimental values than the results of other methods. |
