Special Issue Information

Dear Colleagues,

Structural repairs and renovations are problems faced by most civil engineers, but they are addressed to a much lesser extent in the literature and national regulations compared to new constructions. The main challenges faced by civil engineers when repairing or renovating a structure are which repair technique to use and in what way to prove the mechanical resistance and stability of the renovated structure. These problems have become more and more pronounced in recent times, taking into account the development of new materials, new rehabilitation techniques, and new numerical methods for structural analyses.

The aim of this Special Issue, entitled “Challenges in Structural Repairs and Renovations”, is to gather knowledge related to new techniques, materials, experimental research, and theoretical calculation methods related to structural repairs and renovations.

We invite authors to submit original research, theoretical and experimental work, case studies, and comprehensive review papers for possible publication. The topics relevant to this Special Issue include, but are not limited to, the following subjects:

  • New techniques used in structural repairs and renovations;
  • New materials used in structural repairs and renovations;
  • Experimental research related to structural repairs and renovations;
  • New calculation techniques for proving the mechanical resistance and stability of structural repairs and renovations;
  • Parametric numerical analyses related to structural repairs and renovations.

Historic masonry towers represent a significant part of the cultural heritage, which is often subject to retrofitting for preservation purposes. Due to the poor quality of the mortar, if present at all, the connection of existing towers to the foundation is generally such that it cannot ensure their monolithic behaviour under seismic action. When choosing a retrofitting technique, engineers often find themselves in a dilemma, whether to strengthen the connection between the tower and the foundation in order to enable the transfer of bending moments from the tower to the foundation due to seismic action, or to leave the towers freely rested on the foundation in order to enable the rocking motion mechanism. The aim of this paper was to investigate how the connection between the tower and the foundation affects the seismic resistance of masonry towers. For this purpose, a series of numerical analyses were performed on 2D numerical models that were created based on the geometry of five towers from the Italian region. In these numerical analyses, each of the towers is subjected to an incremental dynamic analysis in time for the case that it is freely supported on the base and for the case that it is freely rested base. The numerical analyses showed that: (i) unretrofitted towers have relatively low seismic resistance and rocking mechanisms cannot be realised to a significant extent; (ii) retrofitted masonry towers resting freely on the base have a significantly higher seismic resistance compared to the same towers connected to the base due to the rocking motion mechanism. The conclusions drawn on the basis of the conducted studies can serve engineers when choosing a technique for strengthening masonry towers. Full article
