Numerical investigations on RC beam-column structures under collapse phenomenon-a simplified finite element approach
No full textThe dire consequences of progressive collapse in terms of both the economy and lives have led to increased interest in the robust design of buildings. These buildings are resilient and retain their structural integrity by preventing the spread of a local failure into a complete collapse. To achieve this, innovative structural mechanisms are being developed to strengthen local resistance and create alternate load paths. Simultaneously, advanced finite element tools and techniques are emerging to aid the design process, offering a cost-effective alternative to extensive experimental programs. This research has developed and elaborated a computationally efficient simplified finite element approach to study two specially designed robust moment-resisting frames, including the bond-slip behavior. These frames, i.e., intermediate moment frame and special moment frame, have been designed by NIST as external frames of a 10-story building and consist of two beams supported on three columns. The column loss scenario of the central column has been considered in the simplified finite element approach, simulating the experimental tests by NIST. The simplified modeling technique involves the use of limited beam elements for both the beams and columns, as well as zero-length beam elements and rigid links incorporating non-linear behavior for connections. Special attention has been paid towards the rebar and concrete bond-slip behavior near the beam supports. The results indicated that the elaborated simplified finite element approach can efficiently and accurately predict the progressive collapse behavior of the RC frame structure. Also, comparing results with previous experimental and finite element results indicated that including bond-slip behavior is critical to obtain accurate results, especially during the post-elastic phase when the arching action develops into catenary action under large displacements induced by column loss. The presented simplified finite element technique can be satisfactorily applied for the accurate and computationally inexpensive modeling and analysis of RC frame buildings under column-loss scenarios.
Scenario planning & its manifestation in plans
Full text linkUrban planning deals with shaping communities, cities and regions with the aim of making them sustainable for future generations. One of the ways to plan for an unexpected future is by using scenario planning technique. This planning method produces a set of structurally different, but plausible futures that highlight outcomes of relevant policies / regulations and helps a community to prepare for the future. While scenario planning efforts are common, the extent to which it affects plans is not well understood.
In this project, I study regional and city-wide plans of Austin and Denver with a view to analyze whether results of scenario planning process (preferred scenarios and ensuing policies and regulations) are incorporated into various planning documents of cities/regions or not? I started the process by reviewing scenario planning exercise of respective cities and regions, followed by review of regional and city plans with an aim to find connections between planning documents and scenario planning effort. It is a narrative account of how scenario planning exercises have helped in making informed decisions to address future concerns through respective plans.
It is found that scenario planning helps in making informed decisions as to how regions and cities want to address and shape an unpredictable future. However, its usage lacks consistency as it is not used uniformly by local governments and organizations within a region. Austin benefits more from scenario exercise as complete process involves interaction between members of the community and representatives from local governing bodies, whereas Denver region predominantly uses it for policy making. Scenario planning is also recommended to be used with consistency within an entire region in developing and updating relevant plans so that there is a uniformity in the complete region as to how it wants to plan for and address the future both at local and regional level. The variation in the employment of this technique among cities / regions may be attributed to several factors including financial constraints, staff resources and non-availability of relevant data for creation of meaningful scenarios.
The limitation of the study is that scenario planning results are hard to assess since they warrant time and implementation of all the prescribed policies / regulations elucidated in local and regional plans. Therefore, evaluation of the results should be carried out after due course of time in consultation with relevant authorities who can comment on implementation on policies.Submission published under a 24 month embargo labeled 'U of I Access', the embargo will last until 2021-08-01The student, Muhammad Usman, accepted the attached license on 2019-07-15 at 17:54.The student, Muhammad Usman, submitted this Thesis for approval on 2019-07-15 at 17:56.This Thesis was approved for publication on 2019-07-16 at 15:21.DSpace SAF Submission Ingestion Package generated from Vireo submission #14329 on 2019-11-26 at 13:05:58Made available in DSpace on 2019-11-26T20:49:30Z (GMT).

Modelling Value of Time for Trip Chains in Daily Schedules
No full textAbstractThe decision about spending time on an activity, switching to the next activity and transport mode used to travel to the next activity location depends on money value of time; opportunity cost of time at activity. Optimal condition of transition between two activities occurs when their marginal utility of time is equal. The presented framework in this paper models the marginal utility of activity to express the money benefit earned by spending each unit of time at the given activity. The proposed model is generalized for the schedule with any number of activities as contrast to previous studies, where such models were used for schedules with fixed number of activities. This framework can be used to calculate the loss in value of time due decreased activity participation resulting from travel delays

A coordinated Framework for Optimized Charging of EV Fleet in Smart Grid
No full textAbstractElectric vehicles can be sustainable alternative in contrast to conventional fossil fuel powered vehicles only if the green energy is used to power them. Without coordination among electric vehicles and grid operator, it can imbalance the power production and demand. This paper presents an automated coordinated mechanism among EV fleet and the grid operator that plans a charging strategy for electric vehicles while sustaining the grid capacity constraints. The intelligent planner plans the charging strategy at the cheaper moments and keep the vehicle charged enough to complete its scheduled trips It suggests a charging pattern for the electric vehicle by using the time dependent electric prices and available power at the given time slots. It also ensures the cheapest charging cost and fulfills the constraints of battery state of the charge. A central power tracker is also introduced which keeps track of the available and required power at each time slot. According to the current market share of the electric vehicles, a fraction of the daily agendas, created by an operational activity-based model, is used to test the framework. Moreover, an experiment has been set up, it makes use of wind and solar renewable energy to power the vehicles

Exploring the influence of privacy management tools on online information sharing decisions
No full textWe explore the role of privacy management tools in online social networks and their influence on
user’s information sharing behavior. Using privacy regulation theory and social capital theory, we first
develop a model that characterizes how and why individuals share their private information. Next, we
use inclusive and exclusive modes of decision making to develop two tools for sharing information.
Subsequently, we test our theoretical model through these tools in the context of online privacy. We
find that privacy management tools not only influence sharing decisions when information sensitivity
varies, but the tools also influence how individuals interpret their tie strength with their friends.Business, Sauder School ofGraduat

Essays in information privacy
No full textThis thesis explores absence of proficient online privacy markets, where sellers can offer privacy enhanced services to consumers, who value privacy. Over three papers, I provide insight to aspects that hinder these markets and potential ways to remedy them. In the first paper, I contend that the changing nature of transactions in online markets – transactions that include consumers’ personal information – has introduced another aspect of uncertainty: privacy uncertainty. I theoretically explore the relationship among privacy uncertainty and seller and product uncertainty. Since uncertainty is the result of information asymmetry, I delve deeper into the nature of information asymmetry by distinguishing between its pre-purchase and post-purchase aspects and their respective effects on privacy uncertainty. Using lab experiments, I demonstrate that post-purchase information asymmetry leads to higher privacy uncertainty, a result that discredits the contemporary practice of using “notice and consent” in online markets. The second paper explores how sellers can improve the communication of their privacy practices and profit from them. To achieve this I define what good privacy practices mean and describe how to measure the quality of such practices. I theorize that app sellers can make better privacy claims if they also include data that supports their privacy claims and provide information about the practices of other similar app sellers (category-claims). I study these propositions across three experiments and find that category claims lead to greater perception of privacy quality as well as willingness to buy.
While prior privacy literature has placed an emphasis on understanding consumer privacy preferences at the time of information disclosure, the last paper explores what happens after the information has been disclosed. In particular, I am interested in understanding consumers’ behavior after they experience a privacy failure, which occurs when consumer’s expectations about collection, use and protection of their personal information are disconfirmed. Using the critical incidence technique, we surveyed 321 individuals who had experienced a privacy failure and found that consumers predominantly react by exhibiting “helplessness”, which can be alleviated by providing a simple recovery mechanisms and privacy controls that enable consumers to add, remove and monitor their collected personal information.Business, Sauder School ofGraduat
