TLDR
In this article , the authors performed a fragility analysis of RC buildings subjected to seismic loading and found that the performance of building structures is highly affected due to the setback, and the seismic fragility is more pronounced when setback passes from level 1 to level 4.About:

Comparison of RC girder bridge and building vulnerability considering empirical seismic damage
TL;DR: Wang et al. as discussed by the authors explored the vulnerability of a reinforced concrete girder bridge and reinforced concrete building during an earthquake, and compared the difference in the seismic capacity of the two types of engineering structures, the nonlinear vulnerability numerical and probabilistic model analysis methods were combined.

Development of a low cost system for modal parameters identification under ambient vibration: A low rise building as a case study
TL;DR: In this article , a low-cost acquisition and processing system which is more appropriate to low-rise buildings was developed. But this system can measure the response of this kind of structure under ambient solicitations and extract its modal parameters with high precision.

Vulnerability assessment of RC buildings with irregularities using probabilistic analysis
TL;DR: In this article , the performance of multistorey reinforced concrete buildings with different irregularities under seismic excitations, using pushover analysis, was investigated using the software ETABS, and the capacity curves generated using pushingover analysis were transformed into bilinear curves and the roof displacement at the yield and ultimate levels were obtained.

Parametric analysis on seismic performance of reinforced concrete frame‐shear wall structures with different setback configurations
TL;DR: In this paper , an extensive parametric study on the seismic performance of reinforced concrete (RC) frame-shear wall structures with different setback configurations was presented, and the overall conclusion is that setbacks caused more than 50% reduction of floor area or positioned at the middle and lower height should be avoided.

Seismic damage evaluation in urban areas using the capacity spectrum method: Application to Barcelona
TL;DR: The vulnerability of the buildings is significant in Barcelona and, therefore, in spite of the low-to-moderate seismic hazard in the region, the expected seismic risk is considerable.

Seismic fragility analysis of low-rise unreinforced masonry structures
TL;DR: In this article, a structural modeling method is proposed such that it can be effectively used for fragility analysis without significant increase in computational time, and maintains an acceptable level of accuracy in representing the nonlinear behavior of the structures.

Vertical geometric irregularity in stepped building frames
TL;DR: In this paper, the authors proposed a regularity index to assess the degree of irregularities in a stepped building frame, and also proposed a modification of the code specified empirical formula for estimating fundamental period for regular frames, to estimate the fundamental time period of the stepped building.

Two frugal options to assess class fragility and seismic safety for low-rise reinforced concrete school buildings in Southern Italy
TL;DR: A study is presented on the seismic fragility of a sample of 15 reinforced-concrete school buildings built between 1960 and 1980s in the province of Foggia, Southern Italy, for which near-perfect information is provided on geometrical and mechanical parameters.
