Seismic Risk Evaluation by Fragility Curves using Metamodel Methods [PDF]

, 2021
This study proposed an efficient and reliable fragility estimation by metamodel methods. To evaluate seismic risk, it is important to account for ground motions and structural parameter uncertainties.

Seismic Fragility Analysis of Buildings Based on Double-Parameter Damage Models considering Soil-Structure Interaction

Advances in Materials Science and Engineering, 2019
Most conventional seismic fragility analyses of RC buildings usually ignore or greatly simplify the soil-structure interaction (SSI), and the maximum interstory drift ratio (MIDR) is often adopted to establish seismic fragility curves.

Multidimensional seismic fragility analysis of subway station structures using the adaptive bandwidth kernel density estimation and Copula function

Underground Space
Structural damages during an earthquake are typically controlled by seismic demands, which are represented by the combination of amplitude of ground motion and cyclic load effects.

Development of the seismic fragility assessment methodology for seismic isolated NPP structures [PDF]

, 2019
As demonstrated by the 2011 East Japan Great Earthquake, earthquakes are a major risk contributor to nuclear power plants (NPPs). Seismic isolation is one of the most effective alternatives for enhancing the seismic safety of NPPs.

Kriging Metamodel-Based Seismic Fragility Analysis of Single-Bent Reinforced Concrete Highway Bridges

Buildings, 2021
Uncertainty quantification is an important issue in the seismic fragility analysis of bridge type structures. However, the influence of different sources of uncertainty on the seismic fragility of the system is commonly overlooked due to the costly re ...
