Quantifying The Onset Of Damage For Light Frame Wood Buildings In Induced Earthquakes, Bridger William Baird Jan 2019

Quantifying The Onset Of Damage For Light Frame Wood Buildings In Induced Earthquakes, Bridger William Baird

Civil Engineering Graduate Theses & Dissertations

Since 2009, the frequency of (moment) magnitude (M) 3.0 earthquakes and larger in the Central United States, and especially Oklahoma, has risen from an average of 2 per year, to 200-700 per year. This increase in seismicity is a result of the deep injection of large quantities of wastewater from oil and gas activities underground.

In this study, damage to built infrastructure from induced earthquakes is investigated through nonlinear dynamic analysis and probabilistic damage assessment for light-frame wood structures common in Oklahoma. Specifically, we focus here on investigating the smallest magnitude of injection-induced earthquake that may cause damage to ...


Seismic Performance Of Underground Reservoir Structures, Ashkaan Hushmand Jan 2016

Seismic Performance Of Underground Reservoir Structures, Ashkaan Hushmand

Civil Engineering Graduate Theses & Dissertations

The majority of stiff-unyielding underground structures have performed well in recent earthquakes. The few cases of failure are mainly related to construction in poor ground conditions (e.g., soft fill, liquefiable soils, sloping ground) and inadequate or no seismic design. Currently there is disagreement among engineering professionals and design methodologies on seismic forces and deformations experienced by these structures, sometimes resulting in inaccurate design that maybe un-conservative or over-conservative. The current procedures used to evaluate seismic loading and deformations of these structures rely on over-simplified analytical methods or advance numerical tools that have not been validated against physical model tests ...


Probabilistic Assessment Of Building Response To Simulated And Recorded Ground Motions, Kristen Leigh Rowe Jan 2011

Probabilistic Assessment Of Building Response To Simulated And Recorded Ground Motions, Kristen Leigh Rowe

Civil Engineering Graduate Theses & Dissertations

This study examines the response of reinforced concrete (RC) frame buildings to both, physics-based ground motion simulations and recorded ground motions time histories. Nonlinear dynamic analysis is used to evaluate the response of six archetypical RC frame buildings to a set of three simulated and three recorded earthquakes. Using probabilistic analysis, building response is examined and statistically compared to determine whether the broadband ground motion simulations and the recorded ground motion time histories yield similar distributions for building response. Important aspects of the ground motion time histories which may cause differences in building response are then examined to attempt and ...
