Testing and finite element analysis of reinforced concrete column footings failing by punching shear

The new damage assessment criteria of reinforced concrete column was analyzed and defined in the paper. RC column finite element analysis model was established, then damage patterns of the explosion impact on RC column are obtained by means of numerical simulation. The P-I curve of RC column is ascertained. Based on damage criteria and finite element analysis result, we put forward a simplified numerical method to ascertain RC column P-I curve. By contrast, the applicability and validity of simplified numerical method is satisfactory.

Rc Column

Slender reinforced concrete column may fail in material failure or instability failure. Instability failure is a common problem which cannot be analyzed with first-order analysis. So, second-order analysis is required to analyze instability failure of slender RC column. The main objective of this study was to construct uniaxial interaction diagram for slender reinforced concrete column based on nonlinear finite element analysis (FEA) software. The key parameters which were studied in this study were eccentricity, slenderness ratio, steel ratio, and shape of the column. Concrete damage plasticity (CDP) was utilized in modeling the concrete. Material nonlinearity, geometric nonlinearity, effect of cracking, and tension stiffening effect were included in the modeling. The results reveal that, as slenderness ratio increases, the balanced moment also increases, but the corresponding axial load was decreased. However, increasing the amount of steel reinforcement to the column increases the stability of the column and reduces the effect of slenderness ratio. Also, the capacity of square slender RC column is larger than rectangular slender RC column with equivalent cross section. However, the result is close to each other as slenderness ratio increased. Finally, validation was conducted by taking a benchmark experiment, and it shows that FEA result agrees with the experimental by 85.581%.

Steel Reinforced Concrete

Nonlinear finite element analysis of abnormal exterior joints consist of Steel Reinforced Concrete column and Reinforced Concrete beam was performed using ABAQUS computation program, the joints failure mode and the skeleton curve were calculated. Comparison with experimental results to prove the reliability of finite element analysis. Then, the paper analyzed different parameters which affect the joints loading capacity, the results indicate that to a certain extent, the eccentricity of the upper and lower column sections and steel ratio both have important effects on the stiffness and ultimate loading capacity of the joints; with the increment of the ratio of axial compression, the joints ductility will be reduced.
