一、问题的提出钢筋混凝土构件中纵向受力钢筋的最小配筋百分率的规定是一个较复杂的问题。它既涉及结构安全,又涉及经济政策。我国现行规范(TJ10—74)的规定,与其他各国规范相比偏低较多。为防止构件脆性破坏,拟对现行规范表34中第三项作适当调整。二、修改意见现行规范规定,受弯构件、偏心受压及偏心受拉构件受拉钢筋的最小配筋百分率为:
First, the issue of the provisions of the minimum reinforcement ratio of longitudinal reinforcement steel reinforced concrete members is a more complex issue. It involves both structural safety and economic policy. The regulations of China’s current regulations (TJ 10-74) are much lower than those of other countries. In order to prevent brittle fracture of components, it is proposed to make appropriate adjustments to the third item in Table 34 of the current code. Second, the revision of the current specification provides that the minimum percentage of reinforcement for the flexural members, eccentric compression, and the tension members of the eccentric tension members is:
