The flexural behavior of non-holomorphic circular pile and cylindrical pile is respectively evaluated based on the results of finite element analysis with ABAQUS. It is presented that the ultimate bearing capacities of non-holomorphic circular pile and cylindrical pile have little difference. The displacement ductility ratio of non-holomorphic circular pile lies between 3.38 and 3.64, indicating that the NHC pile has better ductility.

In order to study the performance of concrete frame columns that reinforcedby assembleinclined web steel truss, with the same reciprocatinghorizontal displacement and different axialcompression.It canbe calculate the mechanical behavior of concrete frame columns and reinforced columns by using the finite element analysis software ABAQUS. Simulation analysis shows that the bearing capacity ofreinforced columnshas greatly increased andpresented a full hysteresis curve. The result shows that the reinforcement method of assemble inclined web steel truss can greatly improve the bearing capacity and ductility of the concrete frame column, and the axial compression is larger, the better the reinforcement effect.

The nonlinear finite element analysis for the flexural behavior of the concrete beams reinforced with CFRP-PCPs Composite Rebars,which was a new structural form, has been studied in ANSYS. The effects of material nonlinearities of concrete £¬steel rebar £¬CFRP rebar were considered in the analytic model. Load-displacement curves were received through calculation in this paper. Compared the present result with the experimental results has proved that the model provided is correct and convenient for the analysis of the beams.

Modeling Process

In this paper, in order to understand fully the development of failure mechanism, bearing capacity and seismic performance of the steel H-beams and composite concrete filled steel tubular (CFST) column joints strengthened by outside strengthening ring, in the space zone the effects of changing the axial compression ratio is investigated. A 3D joint finite element model is built up by finite element software ABAQUS, the elastic-plastic finite element analysis is carried through numerical modeling process. The analysis results showed that low axial compression ratio has a little influence on the bearing capacity; with the increase of axial pressure the bearing capacity will decrease in a high axial compression ratio, moreover the failure pattern of joint changes from beam end to column end. The ductility of the specimens is decreased by raising axial compression ratio.
