...-reinforced concrete. The variation in bond performance for the different reinforcements was investigated. Fatigue tests were then performed, followed by further pull-out tests to determine the bond stress–slip curves between concrete and reinforcements, and the influence of fatigue action on the bond stress...

..., which delays any delamination failure. Thus, fatigue losses in the elastomer layers are used to characterise the damage induced in the UFREI due to multiple hazards throughout the timeline. Maximum principal strain in elastomer layers at various displacement amplitudes is calculated using finite-element...

... had adequate shear capacity but made little contribution to flexural stiffness and capacity. Semi-deep beam specimens were fabricated and tested under cyclic loading. The results showed that the beam connections with SWs and HTWs had 30% and 20% less fatigue damage respectively than those with TWs...
