摘要:
分析外贴纤维布加固砼梁截面的弯矩 -轴力 -曲率关系,计算梁的屈服、极限弯矩和曲率,以及延性系数 .计算结果表明,随着配筋率和纤维配置率的增加,纤维加固效应、极限应力和梁的延性降低 .在较高的配筋率和纤维配置率情况下,实验的破坏特征与计算的不一致 .
Abstract:
In relation to the concrete beam with fibre sheet sticking on externally for its reinforcement,the relationship between bending moment-axial force-curvature of its section is analysed; and its yield and ultimate bending moment and curvature and also the coefficienf of its ductility are calculated.As indicated by results of calculation, along with the increase of steel ratio and fibre collocation,effect of fibre reinforcement and utlimate stress of fiber sheet and ductility of beam will decrease. Under the conition of a higher steel ratio and fibre collocation, the characteristic of experimental type of failure is inconsistent with that of calculating type.
