Shear Mechanism and Capacity Calculation of Steel Reinforced Concrete Special-Shaped Columns
Abstract eng: Through experiments on 17 steel reinforced concrete (SRC) special-shaped column specimens under low-cyclic reversed loading, loading process and failure patterns of SRC special-shaped columns with different steel reinforcement are observed. From the experiments it is shown that the failure patterns of these columns include shear-diagonal compression failure, shear-bond failure, shear-flexure failure and flexural failure. The failure mechanism and characteristics of SRC special-shaped columns are also analyzed. For different SRC special-shaped columns, based on the failure characteristics and mechanism observed from the test, formulas for calculating ultimate shear capacity in shear-diagonal compression failure and shear-bond failure under horizontal axis and oblique loading are derived. The calculated results show very good agreement with the actual experimental measurement. Both the theoretical analysis and the experimental results show that, shear capacity of T、L shaped columns under oblique loading are larger than that under horizontal axis loading, whereas the shear capacity of ┼-shaped columns under oblique loading are less than that under horizontal axis loading.
