Special Issue Information

Dear Colleagues,

The capacity of new constructions to resist earthquakes represents a necessity for the protection of human life. In the same way, the improvement of the seismic response of the existing and historical buildings—especially if located in areas only nowadays classified as seismic zones—represents a challenge, both in terms of safeguarding human life and preserving heritage. Therefore, this Special Issue addresses either the aspects related to the seismic analysis, such as the different implementation’s ways and the different analysis methodologies (non-linear static or non-linear dynamic analyses), or the structural solutions able to improve the seismic response of new and existing buildings. For these reasons, this Special Issue is focused on the construction of new civil structures characterized by innovative materials (as graphene concrete, composites, etc.), viaducts (new and existent ones, especially if afflicted by structural degradation), and underground constructions (located in very strong seismic sites). However, we also wish to develop discussions about the masonry of historical buildings, for which seismic improvement is a mandatory requirement. We welcome manuscripts reflecting original work on topics including, but not limited to:

  • characterization of structural damage limit states;
  • Surveys and monitoring to determine the existing structures conservation’s state;
  • advanced experimental methods for seismic performance evaluation;
  • numerical models for materials and structural elements;
  • improvements in seismic response;
  • relevant construction techniques for seismic improvement.

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 semimonthly journal published by MDPI.

The assessment of the seismic performance of transportation infrastructures is of primary importance for the management of the aftermath of an earthquake. To perform such an assessment, various modeling approaches characterized by different levels of accuracy are available and modern seismic design codes provide recommendations about their use. Non-linear time-history analysis (NLTHA) is acknowledged as the most reliable method, but is difficult to implement and is computationally expensive. This paper aims to investigate the viability of less complex methods, but with low computational cost, for the assessment of straight, multi-span bridges and compare their performance against the results of NLTHA in order to quantify the expected accuracy. The study is developed considering three bridge archetypes with either simply-supported or continuous-deck layouts, representative of typical features of the Italian bridge stock. The bridges are analyzed first through nonlinear dynamic analyses, to define the benchmark solution; then linear dynamic analyses, such as Linear Time-History and Response Spectrum Analysis, nonlinear static analyses, such as MPA (Modal Pushover Analysis), and Equivalent Static Analysis are considered. A comparison among the examined procedures is eventually proposed, highlighting the strengths and weaknesses of each approach. Full article
