In order to study the mechanics properties to of concrete columns with embedded steel, analysis models of SRC columns are established by using finite element software ABAQUS. Firstly, in order to validate the rationality of the analytical model, the test specimens are modeled, the results obtained from the finite element and experimental analyses are compared to each other, it is found that the finite element behavior indicates a good agreement with the experimental behavior. Furthermore, the ductility and ultimate capacity of SRC columns are studied with the changes of steel bone ratio and the axial compressive ratio. Analytical results demonstrate that embedded steel improves the ductility of SRC columns with large axial compressive ratio and steel bone ratios have obvious effect on ductility and ultimate capacity of SRC columns. The study results have some value on the design and application of the SRC columns.

Finite element analysis could be used as a supplementary means to investigate mechanical behavior. ABAQUS software is conducted to analyze steel reinforced concrete (SRC) columns. Firstly, in order to validate the rationality of the analytical model, finite element models of test specimens are established to simulate the test process. By comparing the analytical results with experimental ones, it is found that the results from finite element analysis coincide well with that from test. So ABAQUS software could be used as a supplementary means to simulate SRC column mechanical behavior . Further the ductility and ultimate capacity of SRC columns are studied with the changes of steel bone ratio and the axial compressive ratio.

Damage Constitutive Model

To analyze the mechanical properties of steel tube filled with steel-reinforced concrete(STSRC), the mechanical models and some related problems of STSRC under different loading ways are proposed for the analysis on the base of finite element software: the concrete plastic damage constitutive model, the contact between steel and the treatment of boundary condition, etc. There are three types of specimen for analysis: short column, long column and pure bending beam. The results indicate that the mechanical models and the relevant technical analysis of STSRC are reasonable, and are beneficial to convergence. The discussed methods can provide a reference for the scholars to study on other composite steel-concrete structures.

Hysteresis Characteristics

In order to study the mechanics properties to of concrete columns with embedded steel, two groups contrasting analysis models referring to SRC column and RC column are established by using finite element software ABAQUS. Both Static and cycle force are conducted. Analytical results show that bearing capacity and deformation ability of steel embedded reinforced concrete columns (SRC) under static loading are obviously higher than those of the reinforced concrete column (RC). Under the cycle force, the hysteresis circles of the SRC columns are fuller than RC column. The capability of energy consumption of the SRC columns is almost 1.4 times more than the RC columns. Further axial pressure coefficient and stirrup ratio are considered as parameters to study hysteresis characteristics, energy dissipation and the influence of the skeleton curve of SRC columns. The analytical results demonstrate that the hysteresis characteristics and energy dissipationare different with the changes of axial pressure coefficient. Meanwhile, the stirrup ratio of SRC column has little effect on energy dissipation. The study results have some value on the design and application of the SRC columns.

The numerical analysis results are compared with the data of the experimental research. The advantages and shortcoming of the finite element model are given. A better numerical simulation method and a use for reference to the similar case are expected to be afforded.

Strength And Ductility

Non-linear finite element model of prestressed steel reinforced concrete(PSRC) beams were carried out by using software ABAQUS. The effects of the parameters of non-prestressed reinforcement ratio, prestressed reinforcement ratio, effective prestressed force and non-prestressed tendons yield strength on the ultimate strength and ductility of PSRC beam were investigated. It is found that increase of the tension reinforcement ratio has little impact on the ultimate deflection but can improve the ultimate capacity of PSRC beam. Increase of the prestressed steel ratio can significantly improve the cracking load, stiffness and ultimate capacity of PSRC beam. The effective prestressed force can improve the bearing capacity of PSRC beam.

This paper studies the working mechanism, ductility, and ultimate load bearing capacity of the composite columns through axial load bearing capacity experiments on eight steel skeleton-steel pipes reinforced composite concrete columns. The results show that the collaborative work between the steel pipe, steel skeleton and concrete can effectively improve the bearing capacity of the column, delay or inhibit the spread of shear diagonal cracks in the concrete and improve the ductility of the column. In addition, the finite element software ANSYS is used to digitally simulate the whole process of axial pressure test, and the resulting load-displacement curves and experimental curves agree fairly well.

Before And After

A quasi static finite element method for assessing cyclic bearing capacity of semi-circular guiding dike on natural or reinforced soft clay foundation is developed by combining the concept of cyclic shear strength with D-P yield criterion. Then the proposed method is numerically implemented in the framework of the large universal finite element software. Combining with a practical engineering, the stability of semi-circular guiding dike before and after foundation reinforcement is analyzed. The results showed that the foundation bearing capacity decreases obviously when cyclic weakening effect of soft foundation was considered, so cyclic weakening effect of soft foundation under cyclic wave load should be considered in practical design. Moreover, foundation reinforcement has an obvious effect to increase foundation bearing capacity.

The ultimate load-bearing capacities of axially-loaded steel tube composite column filled with steel reinforced concrete under three-dimensional stress based on the unified strength theory are analyzed in this paper. The influence of thickness-length ratio and scale effect are considered by introducing the reduction factor of equivalent constraints and concrete strength reduction factor, respectively. The nonlinear three-dimensional finite element analysis of the steel tube composite column filled with steel reinforced concrete is performed by the finite element software ANSYS. The numerical and the analytical results are compared with experimental results and good agreement can be observed. A series of numerical simulation technologies is studied and described in detail, such as selecting element type, defining material model of steel and concrete, establishing global finite element model with discrete reinforced bars elements, applying loads to the specimens, and setting solution controls option. The results indicate that ANSYS finite element software may well simulate the behavior of the steel tube composite column filled with steel reinforced concrete under axial compression through reasonably selecting parameters.
