Educational shaking table modules for earthquake engineeringInamdar, Nikhil Jayant 17 February 2011 (has links)
The goal of the project is to develop, build, and test a modular steel structure that can be tested on an educational shaking table to demonstrate structural dynamic and earthquake engineering principles. The advantage of the structure is that it can be tested into its non-linear range and yielded parts can easily be replaced for subsequent tests. The steel modular structure represents a multi-story moment resisting frame and is comprised of sheet metal beams and columns bolted to “rigid” steel angles. This structure is tested on a unidirectional shaking table, viz. “Quanser Shake Table II”. The structure is designed to achieve a specific mode of failure through non-linear analysis. A non-linear pushover analysis is carried out to determine stiffness and strength of the structure as well as potential hinge locations. Eigen-value analysis is undertaken to determine all the natural periods and frequencies that will help in understanding its dynamic response. The structure is analyzed and tested for various ground motions to study the effects of an earthquake on a multi-storied frame. Educational modules provide a set of experiments that can be easily performed on the test structure. / text

Human response to earthquake shaking : analysis of video footage of the 2010-2011 Canterbury earthquake sequence.Lambie, Emily Susan January 2014 (has links)
Research on human behaviour during earthquake shaking has identified three main influences of
behaviour: the environment the individual is located immediately before and during the
earthquake, in terms of where the individual is and who the individual is with at the time of the
earthquake; individual characteristics, such as age, gender, previous earthquake experience, and
the intensity and duration of earthquake shaking. However, little research to date has
systematically analysed the immediate observable human responses to earthquake shaking,
mostly due to data constraints and/or ethical considerations. Research on human behaviour
during earthquakes has relied on simulations or post-event, reflective interviews and
questionnaire studies, often performed weeks to months or even years following the event. Such
studies are therefore subject to limitations such as the quality of the participant's memory or
(perceived) realism of a simulation.
The aim of this research was to develop a robust coding scheme to analyse human behaviour
during earthquake shaking using video footage captured during an earthquake event. This will
allow systematic analysis of individuals during real earthquakes using a previously unutilized
data source, thus help develop guidance on appropriate protective actions. The coding scheme
was developed in a two-part process, combining a deductive and inductive approach. Previous
research studies of human behavioral response during earthquake shaking provided the basis for
the coding scheme. This was then iteratively refined by applying the coding scheme to a broad
range of video footage of people exposed to strong shaking during the Canterbury earthquake
sequence. The aim of this was to optimise coding scheme content and application across a broad
range of scenarios, and to increase inter-coder reliability.
The methodology to code data will enhance objective observation of video footage to allow
cross-event analysis and explore (among others): reaction time, patterns of behaviour, and social,
environmental and situational influences of behaviour. This can provide guidance for building
configuration and design, and evidence-based recommendations for public education about
injury-preventing behavioural responses during earthquake shaking.

The effect of the Canterbury earthquakes on alcohol consumption and motivations for drinking among psychologically resilient individualsMarie, Leila Michele Anastasia January 2014 (has links)
Individual responses to natural disasters are highly variable. The psychological and behavioural response trajectories of those who manage to cope well with adverse life events are in need of further investigation. Increased alcohol use is often observed in communities exposed to mass traumas, particularly among those exposed to severe levels of trauma, with males drinking more than females. The current study examined patterns of alcohol use and motivations for drinking among a sample of psychologically resilient individuals with varying levels of exposure to the Canterbury earthquakes (N = 91) using structured and semi-structured interviews and self-report measures. As hypothesised, there was a significant increase in alcohol consumption since the earthquakes began, and males reported significantly higher levels of pre-earthquake and current alcohol consumption than females. Contrary to expectations, there was no association between traumatic exposure severity and alcohol consumption. While participants reported anxiety-based coping motives for drinking at levels comparable to those reported by other studies, depression-based coping motives were significantly lower, providing partial support for the hypothesis that participants would report coping motives for drinking at levels comparable to those found by other researchers. No gender differences in drinking motives were found. As expected, current alcohol consumption was positively correlated with anxiety and depression-based coping motives for drinking. Psychological resilience was not significantly associated with alcohol use, however resilience was negatively associated with depression-based coping motives for drinking. These findings have inter-generational and international implications for post-traumatic intervention.

Assessment of seismic risk for subsea production systems in the Gulf of MexicoBrown, Laura Ann 30 September 2004 (has links)
The number of subsea production systems placed in deepwater locations in the Gulf of Mexico (GOM) has increased significantly in the last ten to fifteen years. Currently, API-RP2A (2000 a,b) designates the GOM as a low seismic zone, and thus does not require seismic effects to be considered during the design process. However, there have been a number of seismic events with Richter magnitudes between 3.0 and 4.9 that have occurred in this region. As a result, questions have been raised regarding the seismic performance of deepwater subsea systems. This thesis presents an analytical parametric study where a prototype subsea structure was selected based on a survey of subsea systems. The baseline analytical model consisted of a single casing embedded in soft clay soils, which supported a lumped mass at a cantilevered height above the soil. A number of the model characteristics were varied in the parametric study to simulate the structural response of a range of subsea structures. This thesis discusses the impact of API-RP2A Zone 1 and 2 design seismic demands for the performance of subsea structures. The results from the subsequent analyses show that the stresses and deflections produced by the Zone 1 and 2 peak ground accelerations fall within the allowable limits.
