Bridge Seismic Assessment

by Ardalan Sabamehr, Ph.D.

 

08/28/19

Key terms 

Modelling, Seismic Retrofit, Seismic Demands

Bridges are assets that are subject to not only varying loads on a daily basis but are also highly susceptible to seismic loading in the event of an earthquake. Additionally, bridges tend to be post-disaster structures and need to be operational at all times...

Bridge Seismic Assessment

Fragility Curves Social Media.png

The type and extent of damage that a component will experience is uncertain. Component fragility functions are statistical distributions that indicate the conditional probability of incurring damage at a given value of demand. Fragility functions are assumed to be lognormal distributions...

Seismic Performance of Highway Bridges

by Rania Bedair, Ph.D. P.Eng.

 

11/15/18

Key terms 

Seismic Performance, Infrastructure, Structural Health Monitoring

Bridges are considered one of the most critical components of highway transportation networks, as the closure of a bridge due to partial damage or collapse can disrupt the entire transportation system. A bridge with slight or moderate seismic damage could decrease its serviceability and ability to transport vehicles...

Mode Shape Curvature

by Ardalan Sabamehr, Ph.D.

 

10/30/18

Key terms 

Structural Modelling, Mode Shape Curvature, Damage Detection

The mode shape curvature is an efficient technique in identifying damage by using the mode shapes of the structure. The curvature is related to the flexural stiffness of the beam’s cross section.  If a crack or other damage is introduced in a structure, it reduces its flexural stiffness (EI) at its cracked section. ...
