“…Dealing with the renovation of multiple buildings is a relevant matter for municipalities and housing associations, requiring to decide which facilities to renovate and in which order (Nielsen, Jensen, Larsen, & Nissen, 2016;Pannier et al, 2021). To ask this question, it should be borne in mind that, on the one hand, improper functioning of different types of social infrastructure may have a different impact on SUD, which makes it necessary to evaluate the relative contribution to SUD for portfolio management purposes (Fathi-Fazl, Lounis, & Cai, 2021).…”

The prioritisation of public facilities' maintenance is a necessary but complex task due to the need of considering both physical and socio-economic criteria. This study addresses this problem by quantifying the improvement in the delivery of social benefits that the corrective maintenance of an urban area's public facilities could yield. Based on this, a decision framework is proposed to design and schedule corrective maintenance plans at a municipal scale. The methodology integrates multi-criteria assessment with an analytical method for evaluating the contribution of an area's public facilities to its sustainable urban development based on their type of social infrastructure and their maintenance condition. The decision framework is implemented as a software to facilitate its application to a case study, consisting in building urban regeneration strategies aligned with governmental guidelines. The results revealed that decision-making is more efficient when considering the facilities' type of social infrastructure. In addition, a cost-efficient prioritisation of corrective measures yields better results than neglecting the economy.

“…Specifically, the very low and low seismic categories correspond to MMI V (no real building damage) and MMI VI (none to slight damage to non-structural components). Existing buildings in very low and low seismic categories are therefore eligible to be exempt from further seismic risk assessment as their 475-year return period shaking is considered too low to cause appreciable damage depending on the consequences of their failure (Fathi-Fazl and Lounis, 2017;Fathi-Fazl et al 2020e). The seismic categorization system in the NRC SRSTs (Fathi-Fazl et al 2018) 2007; Worden et al 2012;Caprio et al 2015;Halchuk, 2017).…”

An update on the seismic categorization for seismic risk assessment of existing Canadian buildings

et al. 2023

An investigation has been done to update key input parameters in the recent seismic risk screening tools developed by the National Research Council Canada for the six seismic categories. In this study, the seismic categorization system in the recent seismic risk screening tools of the National Research Council Canada is extended to include Canadian buildings abroad by including threshold peak ground acceleration values, a more global set of modified Mercalli intensity, peak ground acceleration, and spectral response acceleration and peak ground acceleration relationships. The relationships between spectral response acceleration, peak ground acceleration, and peak ground velocity values have been derived using least-square regression analyses to obtain the threshold values of both peak values associated with various modified Mercalli intensity values for each seismic category. Based on the updated relationships, the seismic categorization system is applied to 679 locations in Canada and 226 locations outside Canada.

Development of a preliminary seismic risk screening tool for existing buildings in Canada

et al. 2018

This paper presents a preliminary seismic risk screening tool to identify buildings whose superior structural and non-structural seismic performance in regions of low seismicity can be assessed based on several key attributes. The tool is designed to exempt buildings from detailed seismic risk assessment if key exemption criteria are met. The exemption criteria are based on: a seismic categorization system linked to anticipated building damage and seismicity; whether or not the building was designed using modern seismic design provisions; and the remaining time that the building will be occupied. The tool also provides a second list of criteria, which if satisfied, will automatically trigger further detailed seismic risk assessment. The decisions rendered by the tool regarding the expected seismic performance of a building are evaluated against the next level of seismic risk screening tool to ensure the consistency. A flowchart is presented to facilitate adoption of the tool by practicing engineers and other end-users.
