By studying the two high-strength concrete frame joints by means of experimental investigate and finite element analysis with the low cycle reversed loading method, it discussed the influence of the steel fiber on the seismic behavior of the high-strength frame joints. The result shows that, mixed with steel fiber can enhance the constraint of the concrete at the joint core area, improve the seismic behavior. Amount of steel fiber can replace part of the stirrup.

Four test pieces with different steel plate center-to-center distances and reinforcement ratios are subjected to low-cycle repeat quasistatic loading to optimize properties as failure mode, hysteretic curve, skeleton curve, energy dissipation parameters, strength parameters, and seismic performance of high-strength concrete low-rise shear walls. The embedded steel plates are shown to effectively restrict wall crack propagation, enhance the overall steel ratio, and improve the failure mode of the wall while reducing the degree of brittle failure. Under the same conditions, increasing the spacing between the steel plates in the steel plate concrete shear wall can effectively preserve the horizontal bearing capacity of the shear wall under an ultimate load. The embedded steel plates perform better than concealed bracing in delaying stiffness degeneration in the low-rise shear walls, thus safeguarding their long-term bearing capacity. The results presented here may provide a workable basis for shear wall design optimization.
