Experimental investigation of the cyclic response of reinforced precast concrete framed structures

Research on Seismic Performance of Reinforced Concrete Frame with Unequal Span Under Low Cyclic Reversed Loading

“…(9). Even though the equivalent viscous damping factor is slightly overestimated as stated by Brunesi [35], it correctly reflects energy dissipation trend of the structure. The small area of hysteretic loop confirms that the RC frame has poor energy dissipation capacity.…”

Component-based reinforced concrete beam-column joint model

“…It is clear nowadays that a proper assessment of the behavior of cast in situ and precast RC‐framed structures, whose safe behavior can generally be ensured by limiting the P –Δ effects and controlling the displacement demand, requires beam–column joint behavior to be explicitly accounted for. This is widely recognized for dynamic/cyclic loading but it is equally true for quasi‐static lateral loading (e.g., see References ). Recent earthquakes in New Zealand (on September 4, 2010, with M w = 7.1, and on February 22, 2011, with M w = 6.2) and in Italy (on 20 and 29 of May 2012, with M w = 5.9 and 5.8, respectively) have highlighted the fact that the main failure modes, due to the main earthquake and following aftershocks, experienced by reinforced concrete (RC) flexible structures were related to failures in beam–column joints, giving rise to soft story mechanisms (e.g., see References ).…”

Hollow precast segmental prestressed concrete bridge columns with a shear resistant connecting element

“…Each cycle was repeated twice to allow for the observation of strength degradation under repeated loading with the same amplitude. Sometime, three cycles per each drift amplitude might be planned to address degradation (Brunesi et al 2015). …”
