Special Issue Information

Dear Colleagues,

For seismic risk assessment, it is of utmost importance to characterise cities in their entirety. Since the subsoil is well defined through microzonation studies, the time has come to draw attention to the built environment and its interactions with the soil.

This Special Issue aims at collecting high quality research papers focusing on the characterization of buildings and structures/infrastructures (strategic buildings, bridges, cultural heritage, lifelines, etc.), neighbourhoods, or entire cities in terms of their structural characteristics (e.g., main vibrational periods, modal shapes, equivalent damping factors and their changes due to damage, etc.), geometric features (e.g., shape, height, area, proximity, etc.), and construction typologies through experimental studies using in situ and remote (ground-based, UAVs, airborne and satellite data) geophysical technologies at different scales and resolutions.

Furthermore, we encourage papers on innovative data analysis techniques and methods for structural identification, seismic damage detection, and soil-structure/city interactions. Finally, studies combining data from different sources or sensors, as well as those that promote dissemination of databases using WebGIS technologies for smart cities also fall within the scope of this Special Issue.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Buildings is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

In recent years, the development of quick and streamlined methods for the detection and localization of structural damage has been achieved by analysing key dynamic parameters before and after significant events or as a result of aging. Many Structural Health Monitoring (SHM) systems rely on the relationship between occurred damage and variations in eigenfrequencies. While it is acknowledged that damage can affect eigenfrequencies, the reverse is not necessarily true, particularly for minor frequency variations. Thus, reducing false positives is essential for the effectiveness of SHM systems. The aim of this paper is to identify scenarios where observed changes in eigenfrequencies are not caused by structural damage, but rather by non-stationary combinations of input and system response (e.g., wind effects, traffic vibrations), or by stochastic variations in mass, damping, and stiffness (e.g., environmental variations). To achieve this, statistical variations of thresholds were established to separate linear non-stationary behaviour from nonlinear structural behaviour. The Duffing oscillator was employed in this study to perform various nonlinear analyses via Monte Carlo simulations. Full article

The sequence of collapsing stages of buildings during strong earthquake shaking is still a poorly understood phenomenon. This study aims to use numerical simulations to improve our understanding of the sequence of phenomena that accompany the collapse of buildings during damaging earthquakes. For that purpose, we use a nonlinear shear-beam model of a building that is excited by a sequence of large horizontal and vertical displacement pulses at its base. The propagation of the input pulses through the structure is simulated by a finite difference scheme. We select the properties of our model to be similar to those of a seven-story hotel in San Fernando Valley of the Los Angeles metropolitan area, which was damaged during the 1994 Northridge, California earthquake. We present results of one example of collapsing response of the model to hypothetical but plausible ground motion close to an earthquake fault. We illustrate the response only for a sequence of horizontal and vertical pulses. We show the differences in the nature of the collapsing sequence for vertical upward and downward pulses of ground motion. Rocking input motions will be added in our future work. Improved understanding of the stages of collapse of buildings will be useful for the development of design strategies to prevent it. Full article
