allwable limit,acceptable limit

The value of the allowable ultimate tensile strain,prestress level,and prestress loss of RC beam externally strengthened with prestressed CFRP sheets are proposed based on the domestic and abroad researches.

通过试验及对国内试验数据分析,提出了预应力碳纤维加固混凝土梁碳纤维的允许极限拉应变的上限、施加的预应力水平、预应力损失的取值,为工程结构加固提供了一定的参考依据。
