“…Because of their importance in the management of the emergency response, medical centers must be designed to achieve high performance levels under severe ground motions. Unfortunately hospitals have proven to be as vulnerable to earthquakes as the population they serve, and in the last decades, moderate or heavy structural damages to medical complexes were reported after ground motions in California, Japan, Iran, India and Italy (USGS -United States Geological Survey, 1996;Achour et al, 2011;Rossetto et al, 2011). Besides, past experience showed that the operation of a healthcare center as a whole depends on the integrity of all its physical components, including not only the structural frame, but also non-structural components (NSCs) and technological content (TC), such as architectural elements and utilities, and medical equipment.…”

The paper illustrates an investigation on the effectiveness of dissipative bracing (DB) systems for seismic retrofit of buildings with sensitive non-structural components (NSCs) and technological content (TC), such as medical centers. The "Giovanni Paolo II" hospital, located in a high seismic prone area in Southern Italy, is chosen as case-study. The retrofit intervention with hysteretic braces is designed according to the Italian Building Code. The seismic response of the hospital building is investigated by means of non-linear history analyses carried out in OpenSees FE code and, in order to verify the full-operation after the earthquake, the integrity of NSCs and TC is checked. The retrofit design, thanks to the stiffening and damping effects introduced by DB system, proves suitable to protect both the structural frame and "drift-sensitive" non-structural components and content even under severe earthquakes (PGA = 0.45 g). Nevertheless, some concerns arise about the suitability of hysteretic braces for the protection of the "acceleration-sensitive" elements of the medical complex. Indeed, during weak earthquakes (PGA = 0.17 g), failures of several of these components are detected which can substantially impair the operation of the hospital in the aftermath of the seismic event.

“…The observation in the field on building materials was implemented based on four categories: namely wood, wood + concrete, traditional brick, reinforced concrete with the brick infill walls, and concrete + steel. The levels of damage to buildings were found principally related to the construction type [37,14,12,15,31,40,41]. In observational studies, it was found that the most resistant structures are made from reinforced concrete and double or single bricks.…”

Establishing factors of building vulnerability towards tsunami hazard

et al. 2019

The objective of this article is to establish the attributes (factors) of building vulnerability towards tsunami hazard, particularly for areas in Padang, Indonesia, as well as those areas with the same characteristics. Within this framework, this study informs the progress towards a more systematic approach to factor development for a Relative Vulnerability Index (RVI) score for assessing the building vulnerability towards tsunami hazard. The RVI score is used to predict tsunami risk zones on building vulnerability. The analysis was conducted to develop the factors that influence the building vulnerability. Developing factors of the building vulnerability to tsunami hazard is a key aspect for assessing the RVI, as their result may misguide local decision-makers to act adequately concerning the local risk if they are based on an inappropriate set of factors. These factors were classified under three distinct groups: 1) internal factors; 2) external factors and 3) water inundation factor. The selection of factors are based on the building and the location characteristics. Therefore, the factors that may influence the risk were listed. Based on the kinds of literature and opinion of practitioners/experts, several imperative factors that affect the risk were identified and studied. The factors were tabulated and were sorted from highest to lowest numbers. Based on the tabulation of these factors, the summary of analysis results for internal factors are: construction material; the number of stories; foundation type; date of the building; preservation condition; ground floor hydrodynamic; shape and orientation of the building. Furthermore, based on the tabulation results for external data factors and tsunami inundation factor, the external factors are: movable object; building row; height of concrete fence; natural barrier; distance from the coastline; distance from the river; obstacle islands and gap between building attributes and water inundation factor is tsunami inundation depth.

“…The earthquakes, which have struck the Emilia Romagna region, can be classified as an inter-regional disaster [10] [11] -that required coordination at the national level -because it involved more than 80,000 people distributed across 40 municipalities (16 in the Province of Modena, 7 in Mantua, 7 in Bologna, 6 in Ferrara, and 4 in Reggio Emilia) and it damaged historic buildings in the largest towns (Ferrara, Mantua, Modena and Bologna). The civil protection of the Emilia-Romagna region is one of the best-equipped and organised in Italy, with a big headquartered in Bologna and huge number of vehicles, manpower, equipment, and supplies.…”
