| Abstract |
This study aims at improving the punching shear capacity of reinforced concrete flat slabs by using
post-installed vertical bolts. The focus was made on the case that the compressive strength of concrete
was lower than specified, which could represent poor construction that needs remediation. Three full-scale
specimens were investigated, i.e. control and two strengthened specimens. One was strengthened by
installing vertical bolts in the slab around the column, while the other was strengthened with a greater
number of vertical bolts together with steel plates on the top and bottom of the slab. The specimens were
loaded monotonically until failure. The results showed that the strengthened samples with vertical bolts
had higher punching shear capacity. However, the predicted punching shear capacity considering typical
shear reinforcement given by ACI318-19 was significantly underestimated. The addition of steel plates could
not only improve the strength of the flat slab but also improve the confinement around the column and
thus making it more ductile. |
