Applicability of the PTVA-4 model to evaluate the structural vulnerability of hospitals in Sri Lanka against tsunami

Abstract: Purpose This paper aims to identify the specific parameters in developing a framework to assess the structural vulnerability of hospital buildings in Sri Lanka against tsunami. Along with that, the adaptability and suitability of the existing global frameworks in the Sri Lankan context are to be assessed. Design/methodology/approach In this study, Papathoma tsunami vulnerability assessment (PTVA)-4 model was used as the base in developing the abovementioned framework. Its adaptability and suitability in asse… Show more

“…37 A study of six Sri Lankan hospitals using the Papathoma Tsunami Vulnerability Assessment (PTVA)-4 model identified two of the hospitals with the highest tsunami risk and specified the vulnerability score of each hospital, identifying their critical points. 38 The fact that no association was found between the hospitals' HSI category and the characteristics studied, such as degree of specialization of the hospital; availability of plans in case of earthquakes, tsunamis, volcanoes, and landslides; plans in case of agents with epidemic potential; occupancy rate; years of age; and beds per person of the assigned population, demonstrates that hospitals in Lima are deficient regardless of these characteristics. In other words, this is not a particular problem but a generalized situation, which implies greater risk.…”

“…Surr components overwhelm the number of natural barriers (nb), rows of surrounding buildings (br), the presence of seawalls (sw), surrounding building walls (n), and the risk of moving objects (mo) (Table 2) (equation 4) [25]: 𝑆𝑢𝑟𝑟 = 1/356 (100(𝑏𝑟) + 84(𝑠𝑤) + 72(𝑛𝑏) + 58(𝑚𝑜) + 42(𝑤)) (4) The water depth determines the exposure value against the building. The score is based on the water depth above the terrain level (Wd) with the maximum water depth (Wdmax) (equation 5) [26]. One of the building resilience factors can be determined by water contact with the floor when an intrusion occurs.…”

“…The concept of hospital resilience has gained popularity due to the high number of health crises caused by natural and non-natural disasters in the past decade [ 1 – 5 ]. Hospital resilience reflects organizational capacity to deal with sudden changes or shocks by absorbing, adapting, or transforming their systems to remain functioning [ 6 ]. Conventionally, the hospital resilience concept was developed from traditional safety management concepts and resilience engineering [ 7 ].…”
