Outline of Final Research Achievements |
When conducting seismic evaluation of existing buildings it is necessary to clarify the differences in the properties of material and reinforced concrete members obtained from existing buildings and concrete manufactured in the laboratory. In this study, the seismic tests were performed using the actual material and members. The following conclusions can be made. (1) Observed modulus of elasticity of concrete was lower than the estimated values calculated from the present equation. (2) Tensile strength could be predicted by the present equation. (3) The present equation for the strength of shear crack recommended in the standard tends for RC members to significantly underestimate the observed value of the original members.(4) The present equation for shear capacity could predict the observed value considering the reduction factors for the lightweight and low strength concrete. (5) Epoxy resin injection significantly improved the seismic performance of the RC members.
