For frame structures subject to seismic design requirements, the strength of their longitudinal load-bearing steel bars must meet the design specifications; when no specific requirements are given in the design, for seismic resistance grades 1 and 2, the actual measured strength values shall comply with the following regulations.   A. The ratio of the measured tensile strength to the measured yield strength of the rebar should not be less than 1.25. B. The ratio of the measured tensile strength to the measured yield strength of the rebar should not be less than 1.3. C. The ratio of the measured yield strength to the standard tensile strength of the rebar should not be less than 1.3. D. The ratio of the measured yield strength to the standard tensile strength of the rebar should not be less than 1.25
