Ultimate load bearing capacity enhancement ratio increases as the longitudinal CFRP layers increase for members with the same steel tube outer diameter.
对于同一系列的试件，承载力提高率随着纵向CF RP层数的增大而增大。
2
The steelratio on the bottom of the large beam ought to be limited to ensure the safety of the joint area under longitudinal orthogonal beam.
对于直交梁以下区域剪切破坏应采用限制大梁底部纵向钢筋的方法予以避免。
