Abstract:
Authors simply analyzed the minimum reinforcement ratio and its determination principles under the non-seismic-resistance and seismic-resistance situations, which were referred to the Chinese concrete design codes in different periods. Meanwhile, the values and determinations of the minimum reinforcement ratio of tensile reinforcement for concrete flexural members under two circumstances were comparative analyzed. Limiting values of the minimum reinforcement ratios in different codes were compared through an example, and the method to determine the minimum reinforcement ratios was suggested. The results show that the concrete design codes of different countries described “the member is not failure immediately after cracking” as the principle to determine the minimum reinforcement ratio. There is a big difference on the minimum reinforcement ratio for non-seismic-resistance member in each code, but for seismic-resistance area, the reinforcement ratio is quite similar in each code, except that the reinforcement ratio in Chinese code is lower than the others.
