Special Issue Information

Dear Colleagues,

The significant increase of devastating seismic events has made the technical-scientific and political communities aware of the seismic vulnerability of buildings located in highly exposed urban areas. In historical centers, the conspicuous construction heterogeneity, in conjunction with the intrinsic typological-structural deficiencies of the buildings, negatively affects their global behavior towards earthquakes. Existing buildings represent the weakest part of the urban heritage and are potentially at risk due to uncertain behavior that is very difficult to predict. The priority is to implement programmatic risk-mitigation measures for the redevelopment of historic centers.

However, a step forward has been made for the protection of assets exposed to risk through appropriate research and development concerning the use of unconventional and sustainable materials aimed at generating safe and sustainable urban spaces. In this case, the assessment of seismic vulnerability, integrated with sustainability and innovation, is a useful strategy for planning and mitigating any systemic urban crises.

Based on the previous premises, this Special Issue aims to encourage the dissemination of ideas and knowledge concerning the assessment and reduction of the seismic vulnerability of existing buildings, favoring interdisciplinary approaches between sustainable architectural and engineering issues. Towards this aim, original contributions containing fundamental and applied research, case studies, or discussions on the state-of-the-art of the following topics are welcome:

Seismic vulnerability: evolution; conceptual understanding, historical analysis, and future multidisciplinary perspectives; failure detection and diagnosis systems; inventories and intelligent digitized structures.

Vulnerability assessment methods and tools: empirical approaches; mechanical analytical methods; advanced numerical simulation; large-scale evaluation methods; analysis of systemic fragility; GIS approaches.

Seismic consolidation and retrofit techniques, sustainable materials, architectural-functional conservation: traditional and innovative strategies; building materials; sustainable buildings; cost–benefit analysis; experimental tests; development and validation; analytical and numerical simulation; application cases; post-earthquake surveys; conservation, protection, and prevention; architectural and functional redevelopment; life-cycle assessment.

In the last few years, several mainshock–aftershock sequences have demonstrated their effects on structures; especially after the occurrence of an earthquake with high magnitude, the number of aftershocks tends to increase. For this reason, several studies have been oriented to estimate the influence of aftershocks on the structural response, most of them in terms of peak or residual displacement; however, energy plays an important role for long-duration earthquakes. In this paper, several bilinear SDOF systems with different post-yielding stiffness are subjected to long-duration seismic sequences, considering different levels of intensity of the aftershocks with the aim to compute constant-ductility spectra for input energy (EI), hysteretic energy (EH) and the ratio between them (EH/EI). The results suggest that although the energy demands tend to increase as the intensity of the aftershock increases, it is observed that the ratio of input and hysteretic energy is very similar for the selected aftershock intensity levels; hence, analytical equations to predict this ratio are proposed. The equations can be used toward earthquake-resistant energy-based design of buildings. Full article
