TLDR
In this paper, a software tool for computer-aided displacement-spectrum-compatible real ground motion record selection was developed for the selection of displacement spectrum compatible real ground motions, with special reference to Italy.Abstract:
The increasing interest in performance-based earthquake engineering has promoted research on the improvement of hazard-consistent seismic input definition and on advanced criteria for strong motion record selection to perform nonlinear time history analyses. Within the ongoing research activities to improve the representation of seismic actions and to develop tools as a support for engineering practice, this study addresses the selection of displacement-spectrum-compatible real ground motions, with special reference to Italy. This involved (1) the definition of specific target displacement spectra for Italian sites, constrained—both at long and short periods—by results of probabilistic seismic hazard analyses; (2) the compilation of a high-quality strong ground motion database; and (3) the development of a software tool for computer-aided displacement-based record selection. Application examples show that sets of unscaled, or lightly scaled, accelerograms with limited record-to-record spectral variability can also easily be obtained when a broadband spectral compatibility is required.

PERPETUATE guidelines for seismic performance-based assessment of cultural heritage masonry structures
TL;DR: In this article, a displacement-based approach is adopted, because these structures crack even for low intensity earthquakes and can survive severe ones only if they have a sufficient displacement capacity, which is the main cause of damage for ancient masonry structures and is necessary to have accurate models for the seismic analysis, able to simulate the nonlinear behavior of masonry, and a well defined performance-based assessment procedure, aimed to guarantee the acceptable level of risk for the occupants and for the conservation of the monument itself.

Seismic assessment of rocking masonry structures
TL;DR: A displacement-based approach based on an incremental limit analysis of rigid blocks is proposed for the performance-based assessment of rocking masonry structures, such as: rocky structures (archeological remains, obelisks, columns, trilithons), arch-piers systems (e.g. triumphal arches, belfries), out-of-plane mechanisms of walls (standing out walls, facades in buildings or churches etc.) or artistic assets prone to overturn.

From rapid visual survey to multi-hazard risk prioritisation and numerical fragility of school buildings
TL;DR: The effectiveness of the INSPIRE data collection form and proposed index is demonstrated in providing a rational method to derive seismic risk prioritisation schemes and in allowing the definition of archetype buildings for more detailed evaluations/analyses.

TL;DR: In this article, a new approach for the derivation of fragility curves, named FRAgility through Capacity spectrum ASsessment (FRACAS), is presented, which adapts the capacity spectrum assessment method and uses inelastic response spectra derived from earthquake ground motion accelerograms to construct fragility curve.

Displacement-based seismic design of structures
TL;DR: The concept of performance-based design of structural systems was first introduced in New Zealand in 1993 as mentioned in this paper, with the goal of designing structures to achieve a specified performance limit state defined by strain or drift limits.

Conditional Mean Spectrum: Tool for Ground-Motion Selection
TL;DR: In this paper, the authors proposed the use of the conditional mean spectrum (CMS) as the appropriate target response spectrum for ground motion selection in dynamic structural analysis, which is a useful tool for selecting ground motions as input to dynamic analysis.
