Special Issue Information

Dear Colleagues,

Many existing reinforced concrete structures located in seismic hazard areas have high seismic vulnerability, as demonstrated in recent earthquakes. The scientific community has been developing strategies and techniques to retrofit reinforced concrete structures, increasing their strength and ductility. Many challenges are currently associated with the development of retrofitting methodologies and solutions that also address sustainability and energy efficiency concerns and requirements. In this line, structural interventions to reduce seismic vulnerability should be combined with the improvement of building energy efficiency, contributing to construction sustainability.

This Special Issue encompasses works related with seismic analyses and retrofitting of existing reinforced concrete structures, including numerical or experimental research works, but also case studies of real interventions. Topics of this SI include but are not limited to the following:

  • Strategies for conservation and renovation;
  • Digital techniques in support to diagnosis;
  • Dynamic identification;
  • Damage detection and prediction;
  • Structural health monitoring;
  • Building information modeling;
  • Statistical analysis;
  • Physical characterization and testing;
  • Mechanical and structural testing;
  • Numerical simulation;
  • Probabilistic assessment;
  • Historic RC constructions;
  • Sustainable retrofitting strategies;
  • Retrofitting techniques and solutions;
  • Seismic assessment and retrofitting;
  • Experimental studies;
  • Codes and standards;
  • Case studies.

This article presents the results of the analysis of the extent of damage to 138 multi-storey buildings with reinforced concrete prefabricated structure, which are located in the mining terrain of the Legnica-Głogów Copper District. These objects are residential and public utility buildings of up to 43 years old, erected in industrialized prefabricated technologies: large-block and large-panel systems. The research was based on the results of technical condition inventory carried out in 2002, 2007 and 2012. As part of the analysis, the damage intensity index wu was established for individual structural and finishing elements of the studied buildings. This index is defined on a six-point scale, which includes a detailed description of the extent of damage that corresponds to the successive degrees of intensity. As part of the research, the databases were significantly expanded and the generalized formulas of the damage intensity index wu for individual groups of buildings were verified. For this purpose, the partial least squares regression (PLSR) method was applied. Thereafter, the analysis of changes of this intensity in time was carried out and the relations between the extent of damage and the impacts of mining exploitation were examined. The approach presented in this paper and obtained research results are characterized by a high degree of utilitarianism and can be applied to increase the efficiency in the optimal maintenance management of buildings, including planning of repairs and retrofits throughout the technical life cycle of the buildings.
