Modelling structural performance and risk for enhanced building resilience and reliability

Risk-Informed Performance-Based Metrics for Evaluating the Structural Safety and Serviceability of Constructed Assets against Natural Disasters

“…These needs include, in a general and definitive way, the essential interests and expectations of society in general (reflected in technical regulations) and others related to individual expectations. End-user needs can be formulated in the following ways [1,5]: (i) in the form of a generic statement that can include the fundamental aspects valued by the end-users (society in general and stakeholders, including individuals) or (ii) in a way that characterizes the performance of the building required to be considered by the user as satisfactory, namely through the naming of qualitative attributes.…”

“…In relation to the first basic requirement laid down by the Regulation (EU) No 305/2011 of the European Parliament and of the Council, i.e., mechanical resistance and stability, the needs of end-users can be formulated by generic statements containing relevant aspects valued by end-users in terms of structural performance or by using qualitative attributes to be met by building structures. These statements can be formulated, for example, as follows [1,14]: (i) safety of structures, protection of people and goods, trustworthiness in commercial transactions [49]; (ii) protection of human lives, limitation of economic losses and maintenance of important civil protection facilities (Eurocode 8); (iii) safety of the occupants of the house [50]; (iv) acceptance, by part of the occupants, of the functioning and appearance of the dwelling and its components, of the activities of the other occupants, of the functioning of the equipment in the dwelling, the comfort provided and the real state value of the dwelling [51]; (v) acceptance, by part of the occupants, of the level of safety and structural serviceability of the dwelling throughout the agreed life span [52]; (vi) protecting the lives of the occupants, preventing injuries to occupants, safeguarding property and property [40]; (vii) protection of human life, safeguarding property, maintaining functionalities and other objectives expected from the building [53].…”

“…These parameters express in a quantitative manner both the agents that act on and/or qualitatively affect the technical behavior of the building (parameters describing technical performance) and the uncertainty associated with achieving performance and/or behavior (parameters describing inherent technical risk). A complete list of parameters that can be used to describe the structural performance and a detailed explanation of the underlying principles for their choice is presented elsewhere [1].…”

“…It is a challenge to ensure resilience and reliability concerns under the ever-increasing performance requirements of the multiple stakeholders involved in the life cycle of building projects [1,2]. In this context, large amounts of technical and non-technical information need to be appropriately managed and communicated [3].…”

“…In the first decade of the 21st century, three major conceptual approaches in the building sector began to merge [12]: quality, performance, and risk. New applications derived from these three interrelated approaches reconcile and integrate conventional management philosophies and enable innovation in the building sector [1,13]. In this context, it is worth mentioning the efforts to organize risk-informed performance-based metrics for construction projects.…”
