Improved seismic fragility modeling from empirical data
The improved empirical fragility model addresses statistical dependence among observations of seismic performances, which arises from common but unknown factors influencing the observations. The proposed model accounts for this dependence by explicitly including common variables in the formulation of the limit state for individual components. Additionally, the fact that observations of the same...
متن کاملInfluence of Flow Velocity on Tsunami Loss Estimation
Inundation depth is commonly used as an intensity measure in tsunami fragility analysis. However, inundation depth cannot be taken as the sole representation of tsunami impact on structures, especially when structural damage is caused by hydrodynamic and debris impact forces that are mainly determined by flow velocity. To reflect the influence of flow velocity in addition to inundation depth in...
متن کاملDeveloping Fragility Functions for Tsunami Damage Estimation Using Numerical Model and Post-tsunami Data from Banda Aceh, Indonesia
Fragility functions, as new measures for estimating structural damage and casualties due to tsunami attack, are developed by an integrated approach using numerical modeling of tsunami inundation and GIS analysis of post-tsunami survey data of the 2004 Sumatra– Andaman earthquake tsunami disaster, obtained from Banda Aceh, Indonesia. The fragility functions are expressed as the damage probabilit...
متن کاملDeveloping fragility functions for tsunami damage estimation using the numerical model and satellite imagery
Recent development of numerical modeling of tsunami and remote sensing technologies enable us to determine the detailed features of tsunami damage. Numerical model with high-accuracy and high-resolution bathymetry/topography grid predicts the local hydrodynamic features of tsunami, such as inundation depth and current velocity. Also, high-resolution satellite imagery provides detailed informati...
متن کاملPower Laws and Fragility in Flow Networks
What makes economic and ecological networks so unlike other highly skewed networks in their tendency toward turbulence and collapse? Here, we explore the consequences of a defining feature of these networks: their nodes are tied together by flow. We show that flow networks tend to the power law degree distribution (PLDD) due to a self-reinforcing process involving position within the global net...
