“…The values of functionality measures must be evaluated as recovery processes are performed. During recovery phases, the states of components in hospitals could be obtained through surveyed data 43 or the results of recovery path analysis 79 . Besides, FEMA P‐58 88,89 provided a method to estimate repair periods with parallel and serial repair strategies.…”

“…The damage states of nonstructural components and equipment were estimated following the methods provided by FEMA P-58. 88,89 Another unique assessment method proposed by Shang et al 79 adopted a circuit-like definition of hospital functionality from an engineering perspective as the ratio of the number of successful paths N(t) to provide medical services to patients to the number of total possible paths N total of emergency functionality in hospitals (Equations 8 and 9). The number of treatment paths was determined according to the state tree model (ST) 90,91 developed from FTs.…”

Hospitals play essential roles in modern communities in the lives of people. During and after earthquakes, they are supposed to be resilient and provide continued medical and social services. Resilience assessment methods are essential for determining hospitals' resilience levels, and the results will provide a direct basis and foundation for the design of new hospitals and retrofit optimization of existing hospitals. This paper reviews the resilience assessment methods and performance measures for hospitals subjected to earthquakes. Current assessment methods are divided into indicator‐ and functionality‐based categories, and the performance measures for quantifying the functionality of hospitals are classified into availability, productivity, quality, and hybrid. This study will assist stakeholders and managers in understanding available assessment methods.

“…The aforementioned models and approaches for modeling overall healthcare system functionality can be classified based on the methodology they utilize in conceptual frameworks [164] : empirical methods based on surveys [15] , fault-tree-based models [16,122,133] , state tree-based methods [165] , discrete event simulation models [66] , Leontief based models [166] , and dynamic models [151] . These methods have been used to investigate the impact of different disasters on hospitals and healthcare systems, including seismic events, wildfires [50,167] , climate events [168][169][170][171][172][173][174][175][176] , and other disasters [72,[177][178][179][180][181][182][183][184][185] .…”

Social institutions such as hospitals and schools are among the main pillars of community stability. A drop in the functionality of hospitals and schools is likely to have short-term and long-term effects on a community, including a reduction in medical interventions, an increase in unschooled children, and population outmigration in search of essential social services. However, comprehensive community resilience models that consider the role played by social institutions in community stability following natural disasters are scarce at the present time. This paper provides a literature review and critical appraisal of previous studies on the resilience of hospital and school systems and their impact on community well-being. The review encompasses existing resilience models for single hospitals and schools, their role when connected with other hospitals and schools in a network, their reliance on each other as interdependent systems, and their role in community resilience and stability. Different mitigation strategies and policies to enhance hospital and school systems’ resilience after extreme natural hazards are also summarized. The paper concludes with a series of recommendations to improve current models for social institutions, enhance the connection between existing hospital and school resilience models and community resilience frameworks, and develop social stability indices that policymakers can use in preparing and mitigating future extreme events.

“…The linear recovery function is generally used when there is no information regarding the preparedness, resources available, and societal response. These simplified recovery functions are widely adopted in the recovery assessment of RC frame structures, [23] school buildings, [24] hospital buildings, [26] and hospital network. [47] To ensure structural integrity and safety, the damaged structural components should be repaired before the nonstructural components.…”

“…[20] Besides, there are some other definitions. For example, Shang et al [26] defined the functionality of the emergency department as the percentage of remaining work lines, and Terzic and Villanueva [27] defined the functionality as the ratio of inaccessible functional area within a building.…”

Structural Design Tall Build

Tall buildings are an important part of a city, and their earthquake-induced damage or collapse will lead to heavy losses, extended repair time, and casualties. Therefore, it is essential to quantify and improve the resilience of tall buildings. To this end, this paper develops a component damage-based metric to characterize tall buildings' functionality loss and then proposes a general quantitative evaluation process to evaluate tall buildings' resilience. Next, the evaluation process is applied to a 42-story reinforced concrete frame shear wall building to demonstrate its applicability. Finally, retrofit strategies on nonstructural components are discussed to enhance the building's resilience. It can be concluded that the proposed metric can be effectively used to evaluate tall buildings' functionality loss. The building being studied has great seismic resilience, with resilience values of 99.95%, 98.68%, and 88.69% at service level earthquake (SLE), design level earthquake (DBE), and maximum considered earthquake (MCE), respectively. The influence of nonstructural components on seismic resilience is greater than that of structural components at SLE and DBE levels. It is an effective alternative to enhance the seismic resilience of tall buildings under SLE and DBE by improving the performance of partition walls, ceilings, and equipment.
