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.

In this paper, the dynamic response of concrete wall and steel fiber reinforced high strength concrete (SFRHSC) wall under blast load is simulated with the explicit dynamic finite element method. The J-H-C model is used for SFRHSC and the material parameters are determined based on the test results. The damage and strain rate effects are considered in above material model. The influences of scaled distance on the dynamic responses of walls are investigated and discussed.

In order to verify the feasibility of ABAQUS, finite element simulation analysis is used to a castellated steel reinforced high strength concrete beam (CSRHSC beam) firstly. Then we consider the strength of steel, strength grade of concrete and thickness of steel protective layer as parameters to study the mechanical properties of the beam by ABAQUS. The results show that: The bearing capacity of beam increases when the steel strength improves, but the magnitude of increase will gradually reduce with the increase of steel strength. Along with the strength grade of concrete increase, the yield strength and ultimate strength basically tend to linear increasing, the ductility tend to decreasing. With the increase of thickness of concrete cover, the ductility of the beam improves but the ultimate strength decreases.
