| 摘 要： | 根据《混凝土结构设计规范》（ＧＢＪ１０－８９）对钢筋极限拉应变的限值和平截面假定，推导出受弯构件极限状态下截面受压区最小高度，以此作为新的限定条件将对正截面强度计算方法和结果产生一定的影响。算例表明，在工程设计中考虑这一限定条件是很有必要的。

| Abstract: | According to the ultimate strain of reinforcement in compression specified in the current code 《Design Code of Concrete Structure》(GBJ10-89) and Bernoullis principle, the formulas for the smallest depth of compression zone of flexural RC members at limited state are derived. It will give rise to a certain influence on both the calculation of ultimate strength of such members and the corresponding results to take this as a new confining condition. Numerical examples show that it is really necessary to take this confining condition into consideration |
