TSUNAMI DRAG FORCE CALCULATOR

Calculate the tsunami drag forces generated on a structure for various site, building and tsunami parameters. Drag forces can be calculated based on the Foster et al, 2017 or the ASCE 7-16 formulations. The application will generate timeseries which can be used in Finite Element software either for structural time-history or variable depth pushover (VDPO) analysis. The net forces can be discretized into a set number of application points and can be adjusted for variable tributary widths.

TSUNAMI RELATIVE HOSPITAL RISK INDEX

The tsunami relative risk index (TRRI) for hospitals quantifies the impacts of tsunami on critical units (e.g. Intensive Care Unit, Maternity Ward, etc), as well as the impact on service provision across a network of hospitals. The TRRI is evaluated for three potential tsunami inundation events and is shown to be able to identify issues with both the buildings and functional aspects of hospital critical units.
TRRI can be used by decision makers to simply explore the effectiveness of individual and combined interventions in improving the tsunami resilience of healthcare provision across the hospital system.

HOSPITAL STRUCTURAL ROBUSTNESS ASSESSMENT TOOL

The Hospital Structural Robustness Assessment tool defines a hospital Structural Robustness index (SRI) which can be used to highlight the relative weaknesses of the hospital in relation to tsunami. Hospital robustness attributes and assessment criteria are assigned relative importance of each attribute is obtained through expert opinion surveys, using a pair-wise comparison method following the Analytical Hierarchy Process (AHP). The well-established Papathoma Tsunami Vulnerability Assessment (PTVA) used to define a Structural Robustness Index (SRI).
