It is typically used when describing something that has been damaged or compromised and is an appropriate way to start a sentence or clause. For example, "The inspector observed damage on the roof of the building."
However, the observed damage on the columns (diagonal shear cracks) during historical seismic events such as the 1994 Northridge earthquake and the 1995 Kobe earthquake was partly attributed to the effect of vertical motions (Broderick et al. 1994; Elnashai et al. 1995).
The study showed that it is possible with numerical models to back-calculate the observed damage based on recorded ground motion in the area.
In any case, the best test for such an approach would be to check its results for cities with significant site amplification having already been hit by damaging earthquakes, and where effects of such spectral coincidence could be checked on actually observed damage (e.g., Mexico City 1985; Kathmandu, Nepal 2015; Puerto Viejo and other coastal cities, Ecuador 2016).
In this study, a new framework is proposed for establishing empirical fragility models for groups of structures based on observed damage distribution.
This discussion qualitatively interprets our field and remotely derived observations (Qualitative trends in observed damage section).
The results of the damage localisation on the specimens were compared to the visually observed damage (delaminating, cracks…) and were corrected on the basis of the amplitude correction.
The developed fatigue damage model, which is based on quantified parameters of observed damage mechanisms, predicts with a high degree of precision the response of the material for all applied stresses and at both temperatures considered.
However, the observed damage was not uniform in that similar buildings located on other caliche sites were only slightly damaged.
The results compared with the observed damage distribution show that significant amplification does not occur on most of the caliche deposits for frequencies up to 10 Hz.
Human or construction error could be one of the contributing factors for the observed damage.
Judging from the observed damage, the design of the joints in precast piers should focus on the first joint between the foundation and the pier segment, for crack control.
