Fiber-reinforced polymer tube–confined steel fiber–reinforced concrete column is a novel composite column proposed recently, which consists of a traditional steel-reinforced concrete column and an external glass fiber–reinforced plastic tube for lateral confinement. In order to investigate the axial compression behavior of steel fiber–reinforced concrete columns, a total of 16 square specimens were fabricated and tested under axial monotonic and cyclic compressive loading. Three different configurations of inner shaped steels, including cross-shaped, box-shaped with wielding, and box-shaped without wielding were considered. Two thicknesses of glass fiber–reinforced concrete tubes were also considered as the main experimental parameters. On the basis of test results, a thorough analysis of the failure process based on strain analysis was discussed. The test results showed that steel fiber–reinforced concrete columns exhibited higher ductility and load capacity compared with fiber-reinforced plastic–confined plain concrete columns. Two quantitative indexes were proposed to measure the confinement of steel fiber–reinforced concretes. The axial cyclic mechanical behaviors were discussed through comparative analysis with monotonic behaviors. The remnant strains and modulus of the cyclic behaviors were also discussed.

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.

Abaqus Software

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.

In this paper, the finite element analysis software ABAQUS is used to study the seismic performance of the joints of rectangular steel tubular columns filled with steel-reinforced concrete and H-shaped steel beam in different beam strengths, which are under the same axial compression ratio of 0.2. By the finite element simulation, we can get the load-displacement curves and skeleton curves from the end of H-shaped steel beam. According to the curves and dates, the seismic performance of the joints is analyzed. The shape of each restoring force curves presents for full square spindle, reflecting that the beam-column structure can effectively absorb the seismic energy; with the enhancement of H-shaped steel beam’s strength, the ultimate bearing capacity of the structure is gradually increasing, however, the stiffness and overall stability of the components become worse by degrees; the change of ductility property about the joints is not obvious, showing good seismic performance.
