How does building age influence the seismic fragility of structures?
4 answers
The age of a building significantly impacts its seismic fragility. As structures age, they are exposed to various environmental stressors like carbonation, freeze-thaw cycles, and corrosion. This exposure leads to a deterioration in the seismic resistance of reinforced concrete (RC) structures, increasing their vulnerability to seismic events over time. Studies show that aging structures in moderate to high seismicity regions face a higher probability of progressive failure due to natural stressors and aftershocks. The time-dependent fragility curves of aging structures are strongly affected by corrosion and deterioration, emphasizing the need to consider the construction date in seismic risk assessments. Therefore, understanding the impact of building age on structural resilience is crucial for designing interventions to mitigate the seismic vulnerability of aging structures.
How does building age influence the seismic fragility of structures?
5 answers
The age of a building significantly impacts its seismic fragility. As structures age, they are exposed to various environmental stressors like freeze-thaw cycles, carbonation, corrosion, and deterioration, which gradually weaken the building materials and reduce structural integrity over time. Studies show that aging structures in high seismicity regions are more vulnerable to progressive damage, especially when subjected to multiple seismic events. Time-dependent fragility curves demonstrate that as buildings age, their seismic performance deteriorates, leading to an increased likelihood of collapse under intense ground motions. Therefore, considering the effects of aging and degradation caused by environmental actions is crucial in assessing the seismic resilience and fragility of structures over time.
