Study on the Effect of Design Coefficients on Load-bearing Capacity of Circular RCFT Columns

摘要：

　　Based on the Japan recommendations,the formula of yield strength for RCFT (reinforced concrete filled steel tube) columns was proposed,the effect of experimental coefficient such as concrete strength,diameter-thickness ratio of steel robe,number of steel bars on yield strength of RCFT was analyzed,and strength evaluation formula for RCFT column is tested by experimental results.As a result,the proposed evaluation formula can evaluate yield strength of RCFT column properly.
