The ratio of residual to ultimate bond stress is mainly related to the ratio of cover depth to bar diameter. It was also found that the lightweight aggregate type has little influence on the bond behaviour of deformed bars. Based on the experimental results, empirical formulae for the ...
Dashed line is the deformed midline and the solid line is the ideal midline weight decreased linearly as the distance increased. The final formula is Si,j = (Pi+k,j - Pi-k,j )2 * (48 - k) / 48), k=1 to 47 Where Pi,j is the intensity at point (i,j) of the image, and...
Scale bar, 100 μm. To determine whether the increase in autoreceptor levels in Deaf-1-deficient animals altered serotonergic function, immunofluorescence was done using anti-5-HT antibody to detect serotonin in the DRN (Fig. 7A). As observed for TPH+ cells, there was no change in the ...

where C is the cover to the center of the rebar, u is the average bond stress acting on the surface of the GFRP rebar, db is the diameter of the reinforcing bar, fc’ is the specified compressive strength of the concrete and le is the embedded length of the reinforcing bar. 8. Exper...
Study on calculating formula of mid-span deformation of concrete continuous beams strengthened with GFRP bars GFRP筋混凝土连续梁跨中挠度计算方法研究 2. The high tensile strength,light weight,anti-corrosion and nonmagnetics of GFRP bars makes them a good structure material. GFRP筋的高强、轻质、耐...
