Cfrp Wrapping

The composite structural element under study is a carbon fiber wrapped, steel I section reinforced concrete column. The wrapped CFRP is under tension and reinforced concrete under radial compression. The aim of the research is to determine the behavior of the composite structural element under axial loads. The Stress-strain characteristics and load bearing capacity of control and CFRP wrapped tubular columns were determined experimentally. Further, Finite element analysis of steel, reinforced concrete and CFRP wrapped concrete columns sections, was conducted using ANSYS Workbench 15.0 software. The experimental and analytical results were compared.

This study presents a design method for hybrid fiber-reinforced-polymer-steel-reinforced concrete beams by an optimized analysis of the cross section. First, the relationships among the energy consumption, the bearing capacity, and the reinforcement ratio are analyzed; then, the parameters of the cross section are determined. Comparisons between the available theoretical and experimental results show that the designed hybrid fiber-reinforced-polymer-steel-reinforced concrete beams with a low area ratio between the fiber-reinforced polymer and the steel reinforcement could meet the required carrying capacity and exhibited high ductility.

Curvature Ductility

Compared with reinforced concrete shaped columns, bearing capacity and ductility of steel reinforced concrete shaped columns are significantly improved, so it is with theoretical significance and practical application of value to research. Based on the plain cross section presume, with material cross-section boundary calculation unit, 15 steel reinforced concrete cross-shaped columns(SRCCSC) have made nonlinear full-rang numerical analysis. It demonstrates that the most adverse curvature ductility load angle of SRCCRSC is 45°.Loading angle (), axial compression ratio (n), and the ratio of spacing and diameter of longitudinal reinforcements (s/d) are the principal factors in curvature ductility of SRCCSC subjected to biaxial eccentric compression. Under the most unfavorable loading angle, through a regression analysis of curvature ductility computer data of 150 cross-shaped columns with 8mm stirrups diameter and 150 columns with 10mm stirrups diameter, it can be obtained with the relationship betweenand axial compression ration,s/d, of SRCCSC subjected to biaxial eccentric compression.

In order to exert the force performance of steel tubular columns filled with steel-reinforced concrete, the focus of the paper is about the influence of load condition on flexural mechanical properties and the shear mechanical properties of the composite columns. The two types of loading conditions are: 1.Steel pipe, steel placed in the steel tube and concrete subject to compressive load simultaneously; 2.Compressive load acts on steel and concrete. The results show that the calculated results based on ADINA and the experimental ones are in agreement well. The calculated results also show that the load condition has no influence on flexural mechanical properties, but has a great influence on shear mechanical properties of the composite columns.
