| 摘 要： | 为获得普通/预应力混凝土构件收缩量的简化计算方法,在素混凝土收缩量的基础上,考虑钢筋及预应力筋的影响,推导出普通/预应力钢筋混凝土构件收缩值的计算公式。对比分析表明,所建议公式的计算结果合理。为便于工程应用,给出了素混凝土早期收缩的建议值。 |

| Abstract: | For acquiring the simplified computational method of the normal/prestressed concrete structural shrinkage quantity,in the present paper,computational formula of the common/prestressed concrete structural shrinkage are derived on the base of the plain concrete shrinkage theory and the consideration of steel bar and prestressed bar influences.Comparative analyze indicates that the result of the formula proposed in this paper is reasonable.For the sake of convenient application,the paper offers recommended val... |
