Special Issue Information

Dear Colleagues,

If we are to address the urgent issue of sustainability in the construction sector, we cannot disregard actions aimed at limiting soil consumption and promoting the reuse of existing structures.

This, however, presents us with the need to find effective and compatible intervention solutions, technically and economically optimized to comply with the current needs in terms of safety, functionality and comfort.

The Special Issue is focused, in particular, on structural intervention strategies for the maintenance, repair and rehabilitation of buildings, with special attention paid to innovative and less invasive solutions, as well as to the use of sustainable materials.

This Special Issue invites researchers to contribute works that advance the state of the art of the relevant topics. These include, but are not limited to, the following fields:

  • Laboratory and in situ experimental tests proving the effectiveness of the interventions (e.g. monotonic tests, cyclic tests, dynamic tests, both on full scale or scaled samples);
  • Discussions on the applicability, compatibility and durability of the interventions and periodic maintenance;
  • Methods to assess the proper installation;
  • Numerical simulations to predict the interventions effectiveness (ranging to simplified approaches to advanced computational models)
  • Analytical strategies for design and performance prediction;
  • Actual applicative experiences and simulated case studies;
  • Original literature reviews and discussions on the topic.

Over the last two decades, the UAE’s construction sector has grown significantly with the development of tall buildings, but the region faces seismic risks. Similar concerns in China led to earthquake simulation research on a city scale. The objectives include developing programming for parallel computing and creating simplified models for estimating losses. The challenges include computational complexity and uncertainties in various modules. In 1995, the structural engineering community adopted performance-based engineering principles, shifting to a probabilistic design process. The Computational Modeling and Simulation Center (SimCenter) implemented this into a generic software platform, with the 2010 release of Regional Resilience Determination (R2D) automating the methodology. A research plan aims to advance realistic seismic simulation in the UAE, integrating studies and custom developments. The goal is to create an end-to-end seismic risk assessment framework aligned with digital trends, such as BIM and GIS. The investigation focuses on a virtual dataset for tall buildings, considering variations in location, material properties, height, and seismic activity. For the studied archetypes, the average expected losses include a 3.6% collapse probability, a 14% repair cost, 22 days repair time per asset, and almost 1.5% total population injuries, ranging from 1% for the lowest severity to 0.15% for the highest.

Buildings with load-bearing structures made of hollow clay blocks with horizontal holes and cement-based mortar are quite common in Italy, yet the current design standards do not consider specific modeling issues to be addressed by practicing engineers. In the absence of peculiar specifications, the prescriptions given for ordinary masonry walls are thus commonly adopted. However, experimental tests proved that walls built with hollow brick masonry performed quite differently from ordinary masonry walls. Considering the in-plane flexural behavior under horizontal loads, unlike ordinary masonry walls that exhibit some ductility, this construction typology performs quite poorly, showing very little deformation capacity and ductility. In recent experimental campaigns, a brittle collapse mechanism was observed due to the toe crush, which entailed the inability of the wall to further withstand the vertical loads. In this paper, the effects of incorrect modeling choices on the characterization of the in-plane behavior of this construction typology and the consequences related to overestimating ductility are discussed; the effects of the reduced ductility on the reliability of the assessment of an existing building as well as on the conceptual design of possible structural retrofit measures are investigated. From the critical discussion, the need emerged to accurately model the in-plane flexural behavior and to update the code provisions to explicitly consider masonry walls with hollow clay bricks with horizontal holes.
