A Proposal of Equation for Bond Splitting Strength of Reinforced Concrete Members Including High Strength Concrete Level

Based on the reversed cyclic loading test of three 1:4 high-strength concrete flat columns, the computer program ABAQUS was used to simulate behaviors of the specimens. Concrete in the column was modeled using the damage plasticity material model, and a uniaxial steel model with combined isotropic and kinematic hardening properties was used to simulate the behavior of the reinforcement. The establishment of the finite element model, definition of the material parameters and the influence of diagonal reinforcement were discussed at length. The results show that the concrete damage plasticity model can be well used for hysteretic analysis of reinforced concrete members if the relevant parameters are reasonably defined. Diagonal reinforcements can not significantly improve ductility of the specimens, but can improve their shear capacities. This paper can provide reference for the performance simulation of reinforced concrete members under cyclic loading.

For expedite the development of high titanium heavy slag concrete, eight high titanium heavy slag high strength reinforced concrete (HTHS-HSRC) scale model column are studied. The eight HTHS-HSRC model columns are tested under reversed horizontal force. Primary experimental parameters include axial load ratio varying from 0.3 to 0.5, volumetric ratios of transverse reinforcement ranging from 1.38% to 1.56%, strength of high titanium heavy slag high strength concrete varying from 55.9 to 61.6 N/mm2 and configurations of transverse reinforcement. It is found from the test result that HTHS-HSRC model columns provides comparable seismic performance to those usually used reinforced concrete column in terms of member ductility, hysteretic and energy dissipation capacity. Primary Factors of Displacement Ductility of Model Columns are also discussed.

The mechanical properties of high-strength concrete was studied in the laboratory, and obtained a high strength concrete uniaxial compressive strength changes with curing period, found that low temperature curing C100 Poisson's ratio of concrete is 0.24, and elastic modulus reached about 52.5GPa. The test results are applied to the numerical calculation, established a separate type reinforced concrete wall, and the multiaxial loading the stress state is simulated, the research shows that it is applied to C100 reinforced concrete shaft lining under its own gravity and the surrounding soil earth pressure, the maximum effective stress are respectively 25MPa , and effective strain is 4E-4mm, structure of shaft wall failure caused by shear wall structure. Under the three state of compression, the strength of concrete is improved.
