Sensing-based Seismic Assessments
by Ardalan Sabamehr, P.Eng., Ph.D.

Key terms 
Seismic Damage, HAZUS, FEMA-P58

Seismic damage predictions can be an important key parameter for asset managers and engineers to increase the general life safety of a given building. One of the most useful and unique features of the Sensequake approach is the ability to directly predict damage levels of structures from sensing tests....

Seismic Performance of Highway Bridges
by Rania Bedair, Ph.D. P.Eng.

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...

Key terms 
Green, Adaptive Reuse, Retrofit

Environmental consciousness is playing an ever-growing role in all professional fields. As support increases, public policies encouraging the implementation of green initiatives to lower global carbon emissions become implemented worldwide. ...

Bridge Seismic Assessment
by Ardalan Sabamehr, Ph.D.

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...

Fragility Curves
by Ardalan Sabamehr, Ph.D.

Key terms 
Fragility Curves, Damage Prediction, Risk Assessment

The type and extent of damage that a component will experience are 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...
