A probabilistic assessment of seismic damage in ductile structures

Earthquake Engineering & Structural Dynamics, 1995
AbstractThe current practices in ductility‐based earthquake design ignore the damage caused by the repeated random inelastic excursions. A ductile structure may however suffer different degrees of damage depending on the number and amplitudes of these inelastic excursions.

Global damage indexes for the seismic performance assessement of RC structures

Earthquake Engineering & Structural Dynamics, 2009
AbstractWhen performing the seismic risk assessment of new or existing buildings, the definition of compact indexes able to measure the damaging and safety level of structures is essential, also in view of the economic considerations on buildings rehabilitation. This paper proposes two series of indexes, named, respectively, Global Damage Indexes (GDIs)

Techniques for seismic damages assessment by using remotely sensed images

IEEE International IEEE International IEEE International Geoscience and Remote Sensing Symposium, 2004. IGARSS '04. Proceedings. 2004, 2004
This paper discusses the methods of seismic damages assessment by utilizing remotely sensed data. Classical Change Detection (CD) algorithms are effective when the author can acquire both pre and post-event images in a very short period of time. For images those have large temporal difference, edge detection and neighborhood operations and occurrence ...

DAMAGE DISAGGREGATION FOR SEISMIC RESILIENCE ASSESSMENT OF AGING BRIDGE NETWORKS

2020
Risk assessment of bridge networks is generally investigated considering damage and disruption caused by sudden extreme events, such as earthquakes. Nonetheless, the structural capacity of aging bridges can be progressively impaired in time due to deterioration caused by environmental stressors, which can have harmful impact on functionality and ...

Graph matching in 3D space for structural seismic damage assessment

2011 IEEE International Conference on Computer Vision Workshops (ICCV Workshops), 2011
One common objective in computer vision and photogrammetry is to infer higher level object structure which is not directly observable in images or other sensing data. A practical problem field for such research is seismic building damage assessment. It is possible to observe objects such as facades, roofs, or rubble piles in oblique airborne images ...

Cultural Heritage and Seismic Disasters: Assessment Methods and Damage Types

2020
The identification of adequate evaluation methodologies of earthquake damages to Cultural Heritage is a highly topical subject, considering the frequency and intensity of the seismic phenomenon, in recent times, in Italy. The subject is related to the broader theme of the attribution of a “monetized” economic value to the cultural assets, widely ...

Seismic Damage Assessment using wavelet analysis

2014
This paper presents a procedure for seismic damage assessment using wavelet analysis. The Morlet wavelet was employed in this approach as a mother wavelet and the continuous wavelet transform is conducted to decompose an acceleration signal at a discrete location in the structure into its wavelet components.

Seismic Damage and Collapse Assessment of Composite Moment Frames

Journal of Structural Engineering, 2001
Damage and stability assessment techniques are developed for evaluating the seismic performance of composite steel-concrete moment frames. The approach features a new seismic damage index based on cumulative member ductility that employs the concept of primary and follower load cycles to distinguish loading history effects.

MODIFICATIONS ON SEISMIC DAMAGE ASSESSMENT SYSTEM OF TCIP BASED ON REPARABILITY

Evaluating the damage state of buildings has always been one of the major challenges that both engineers and authorities face after catastrophic earthquakes in seismic regions. After such events, considering the number of buildings in need of inspection and the insufficient number of qualified inspectors, the availability of a thorough but rapidly ...
