A robust approach for seismic damage assessment

Computers & Structures, 2007
We present a robust approach based on a convex analysis to take into account uncertainties appearing in evaluations of damage to structures during an earthquake. Two kinds of uncertainties are introduced: on the excitation and on the structure. The results obtained by the convex analysis are compared with a Monte Carlo simulation to evaluate the ...

Seismic Damage Assessment of Steel Frames

Journal of Structural Engineering, 1998
The seismic damage analysis of steel frames based on the use of global evaluation indices is addressed. A general procedure is proposed aimed at estimating the degree of damage induced by severe earthquakes in structures not supplied with monitoring systems. Special reference is made to the Park-Ang, McCabe-Hall, and plastic fatigue indices.

Seismic Damage Assessment of Integral Abutment Bridge

2020
Seismic vulnerability assessment of bridge is an important subject in the domain of bridge engineering. Both for functional bridges and new bridges, possible damages during strong ground shaking need to be assessed properly for their performance evaluation and any requirement of strengthening options.

Seismic damage assessment and basis for damage-limiting design

Probabilistic Engineering Mechanics, 1988
Abstract A seismic damage model is developed for reinforced concrete structures in which the structural damage is expressed as a linear combination of the maximum deformation and the hysteretic energy dissipation. From an extensive damage analysis of various reinforced concrete buildings, an intensity scale is derived to describe the potential ...

Seismic damage assessment using linear models

Soil Dynamics and Earthquake Engineering, 1990
The problem of earthquake damage assessment is defined. The role of the analysis of strong motion records in damage assessment codes based on expert systems is pointed out. The behavior of some damage indices proposed in the literature is studied using numerical simulations.

Seismic Damage Assessment of Bridges with Foundation Exposure

2014
In current practice, the foundation systems of most bridges are strategically designed to remain elastic even under severe seismic demands. The bridge foundation is normally assumed to be equipped with large stiffness and strength, so that inelastic deformation due to earthquake excitation occurs in the column instead of in the foundation.

GIS Application for the Assessment of Seismic Damage to Buildings

2009
Geographical Information Systems (GIS) have been found to be very useful in seismic hazard and risk assessment studies. GIS can be used to integrate vast amounts of data geographically, take the spatial distribution of phenomena into consideration and communicate the results graphically, performing analysis of complex mathematical models.

Seismic Damage Assessment of Reinforced Concrete Grain Silos

International Journal of Structural Stability and Dynamics, 2021
This paper deals with seismic performance and damage assessment of concrete grain silos. An existing large silo is taken as a case study to conduct the numerical analyses. A global damage index based on target displacement is proposed to quantify numerically different damage states of the structure.
