- Abstract:
- Authors intended to summarize the research status on shearing performance of square and rectangular concrete-filled tubes(CFT) conducted by domestic and foreign scholars. Characteristics and shortcomings of current studies were demonstrated, further studies also were pointed out. Shearing performances were affected by many factors, such as shear-span ratio, axial load ratio and constraint effect of steel tubes, etc. Unified criteria on the boundaries of each failure pattern was not accepted by all the researchers. According to some test data, calculated results of various bearing capacity formulae were compared, and the reasons of difference were discussed. On the basis of practice requirements, several proposals on the future work were listed in the present research.
