“…In addition to strength increases of the raw materials, an increase in the bond strength between deformed reinforcing bars and concrete has been reported by a number of researchers. [28][29][30] Further understanding regarding the effects of dynamic loading rates is required to determine whether it is necessary to consider rate effects when designing or assessing the seismic performance of structures. In particular, further research at the component level and system level is needed to complement existing material-level knowledge.…”

Summary Understanding the impact of prior earthquake damage on residual capacity is important for postearthquake damage assessment of buildings; however, interpretation of such impact is challenging when based on tests using traditional reversed‐cyclic loading protocols. A new loading protocol, consisting of a dynamic earthquake displacement history followed by quasi‐static reversed‐cyclic loading to failure, is presented as an alternative to traditional simulated seismic loading protocols. Data are analyzed from a set of 12 nominally identical ductile reinforced concrete beams that were tested by using variations of this protocol and traditional reversed‐cyclic and monotonic protocols. Differences in the cycle content of the earthquake displacement histories applied to the test specimens allowed for the effects of load history variation below 2.2% drift to be isolated. It is found that such variation had no effect on the beam deformation capacities. The effects of dynamic loading rates are also analyzed and compared against control quasi‐static specimens. Relative strength increases due to dynamic loading are found to be more significant at yield than at ultimate. Dynamic loading rates led to modest reductions in the beam deformation capacities, but the presence of causality between these variables remains uncertain.

“…Yan and Chen [21] obtained similar conclusions and found that the overall shape of the bond stress-slip curve almost keeps unchanged. In most previous studies [14,15,22,23], the minimum loading time to failure ranges from 0.2 to 10 ms. It was shown that the loading rate increases the strength of concrete around the bond region.…”

“…For deformed bars, the loading rate influences the bond behavior in a positive way [20][21][22][23]. Eligehausen and Popoc [20] chose a pull-out loading rate of 2.83 mm/s to simulate seismic conditions.…”

“…have demonstrated that bond strength under dynamic loads is higher than under static loads (Hansen and Liepens 1962, Shah 1963, Vos and Reinhardt 1982, Yan and Mindess 1991, Weathersby 2003, Solomos and Berra 2010. Although all tests show that bond stress increases with loading rate, a number o f factors were identified to affect the rate o f bond stress increase.…”
