| مستخلص: | Nonlinear finite element analysis (FEA) for the torsion behavior of reinforced concrete '+'-shaped columns with various axial load ratios was carried out by the general software ANSYS. Then a comparison between the FEA calculations and the test results is made. The numerical examples show that: (1) the cracking torque and ultimate torque of reinforced concrete '+'-shaped columns under the combined actions of axial force and torque can be predicted with a reasonable accuracy. (2) the axial ratio has significant effects on the torsion behavior '+'-shaped columns. The cracking torque and ultimate torque of '+'-shaped columns increase with an increase of axial load ratio. Comparing with reinforced concrete '+'-shaped column with an axial load ratio of 0.063, the cracking torque and ultimate torque of reinforced concrete '+'-shaped columns with axial load ratios of 0.189 and 0.314 were increased by 28.3% and 71.9%, 79.4% and 96.0%, respectively. |
