Seismic prone countries have considerably developed seismic design standards for new buildings to resist future earthquakes; however, many existing reinforced concrete (RC) buildings were not designed to appropriately resist the expected seismic effects. This study proposes a retrofit design method for RC buildings using elasto-plastic and viscous...

... DCFs are used to consider the effectiveness of dampers in reducing deformation concentration [24,25]. Figure 10 presents these ratios as a plot on a vertical axis versus the horizontal axis representing the ground motion ID. The DFCs of the retrofitting by both dampers are shown for the 4-story model in Figure 10(b) to (c) for the elasto-plastic damper, and viscous damper while the values for the bare RC frame is shown in Figure 10(a). ...

The results indicate that both dampers could effectively control the DFCs in a similar level to the bare RC frame. ...

Maximum floor accelerations are significant and shown in Figure 11(a) to (c) for the bare RC frame, retrofit by elastoplastic damper, and retrofit by viscous damper, respectively. The maximum floor accelerations were slightly increased by the addition of the elasto-plastic dampers due to the increased stiffness, while viscous dampers tended to slightly reduce the peak floor accelerations. ...

Recent earthquakes demonstrate that prioritizing the retrofitting of buildings should be of the utmost importance for enhancing the seismic resilience and structural integrity of urban structures. To have a realistic results of the pounding effects in modeling process of retrofitting buildings, the present research provides seismic Probability Fact...
Catastrophic earthquakes in the past decades have highlighted the vulnerability of Reinforced Concrete (RC) buildings built in the absence of modern codes. For this reason, a research effort has been dedicated to the development of local as well as global external low-invasive interventions (exoskeletontype) for the seismic retrofit of buildings. I...
A case study of a building in southern Italy, subjected to high degradation by corrosion and waiting to be assessed for retrofit interventions, is presented. The owner required modifications to the building configuration, including a new layout of the floors and retrofitting for a high level of seismic load. A double strategy of an assessment and r...
