Sizing Up Structural Seismic Risk: Latest Technical Performance and Risk Assessment Approaches

Exponent Presents at ICASP14 in Dublin

July 9 - 13, 2023
External Hazard & Risk Assessment: Earthquakes, Floods, Explosions & Earth Movement

While earthquakes are fraught with inherent uncertainties, employing advanced seismic performance and probabilistic risk assessment approaches can provide greater clarity in understanding and mitigating seismic risks to structures and infrastructure.  

As a leader in seismic risk assessment and protective systems, as well as post-earthquake safety and damage assessment, Exponent is at the forefront of cutting-edge techniques and research for evaluating earthquake risks. At the 14th International Conference on Application of Statistics and Probability (ICASP14) in Civil Engineering, Exponent Building & Structures Associate Maha Kenawy, Ph.D., will present on the latest approaches and frameworks for assessing seismic risk to building structures subjected to strong ground shaking and electric power infrastructure subjected to earthquake-induced landslides.

"Probabilistic Risk Assessment of Electric Power Infrastructure Subjected to Earthquake-Induced Landslides"

MONDAY, JULY 10 | 1:30-3:30 IST

Speaker: Maha Kenawy, Ph.D.

Exponent has developed a probabilistic framework to assess the vulnerability of electric power transmission structures to shallow landslides induced by earthquake ground shaking. This presentation will describe the vulnerability of transmission pole structures to differential ground movement during landslide events, as a function of their configuration, material properties, and connectivity to electrical overhead conductors — and more.

"Selection of Near-Fault Physics-Based Simulated Earthquake Ground Motions for Seismic Performance Assessment of Structures"

TUESDAY, JULY 11 | 1:30-3:30 IST

Speaker: Maha Kenawy, Ph.D.

Selecting earthquake records for seismic performance assessment of near-fault structures is challenging. A common approach to represent the near-fault ground motion in engineering analysis is to explicitly consider records with strong directivity pulses (pulse-type records) in ground motion selection. This presentation will examine this approach by using physics-based fault rupture simulations and high-performance computing tools to measure the bias associated with selecting earthquake records for the analysis of near-fault structures.
