Structural Performance Of Reinforced Concrete Flat Plat Buildings Subjected To Fire, Sara Jean George

UNLV Theses, Dissertations, Professional Papers, and Capstones

Reinforced concrete structures are typically considered to have inherent resistance to fire. However, several concrete structures around the world have experienced partial or total collapse under fire. Reinforced concrete flat-plate is a type of structural system widely used for office and residential buildings. Flat plate construction is prone to punching shear failure at slab-column connections which may lead to a catastrophic progressive collapse. The slabs of flat-plates generally have very thin concrete cover leaving steel reinforcement more sensitive to thermal loads. Little is known in the engineering community about the structural performance of flat-plate structures subjected to fire. Through a …

Comparison Of Design-Build And Design-Bid-Build Performance Of Public University Projects, James David Fernane

UNLV Theses, Dissertations, Professional Papers, and Capstones

With an unsure market and scarce work, owners across the United States, especially universities, are finding themselves in situations where they are unable to complete their projects within cost and schedule using the traditional delivery method: Design-Bid-Build (DBB). Under the DBB project delivery method, many competent contractors are electing to send low bids on projects just to keep work on their books, with plans to receive change orders once the project is underway; this practice is leading to cost and schedule overruns. Public universities across the United States are beginning to elect to use Design-Build (DB) as an alternate project …

Advances in controlled environment agriculture (CEA) have made it possible to grow food virtually anywhere in a much more sustainable manner than traditional field-based agriculture. Locating and planning urban farms using retrofitted existing building stock to maximize food production and ease of distribution in Las Vegas requires consideration of multiple barriers related to geography, economics, and the built environment. Consideration of these factors in the planning process informs the design of a successful BIA …

An Exploratory Study On Energy Consumption Of Energy Star And Non-Energy Star Homes, Prajakta Kulkarni

UNLV Theses, Dissertations, Professional Papers, and Capstones

The reduction of energy consumption is one of the economic necessities in the United States due to depleting energy sources in the world. The construction industry is stepping forward to reduce the energy consumption of buildings by efficient designs or by constructing buildings with energy efficient materials and features. In 1992, the U.S. Environmental Protection Agency (EPA) and Department of Energy (DOE) introduced the Energy Star Program to promote energy efficient products with the same or improved services. According to the EPA, Energy Star homes, which use these products, will consume 20 to 30 percent less energy than non-Energy Star …

The Integration Of Biomimicry Into A Built Environment Design Process Model: An Alternative Approach Towards Hydro-Infrastructure, Timothy Lee Albertson

UNLV Theses, Dissertations, Professional Papers, and Capstones

Current methods and processes that support the planning, design and construction of a sustainable built environment include ambiguous principles (Roseland 2000), lack feedback loops (Van Bueren and Jong 2007) and lack a common language between disciplines (Brandon et al 1997). As a result of 3.8 billion years of "research and development" (evolution), nature provides a set of design blueprints that may be used to guide us to create elegant, sustainable, and innovative designs for human technologies (Benyus 1997). The field of biomimicry analyzes nature's best ideas and adapts them for human use (Benyus 1997). The built environment could benefit from …

The state of Nevada receives an average of four inches of …

Evaluation Of Safety Impact Of Access Management In Urban Areas, Xuecai Xu

UNLV Theses, Dissertations, Professional Papers, and Capstones

The access provided by streets and highways to adjacent lands are managed by controlling the spacings between the access points including signals, driveways, and media openings on mid-block segments, and setting the limit on the corner clearances around intersections. There have been studies on evaluating the impact of access management techniques on safety and mobility in urban areas. Samples of mid-block segments and intersections can be collected from selected arterials. Because the mid-block segments or intersections in the same arterials share the same missing information, safety and mobility on them show unique features that should be taken into account when …

Architecture And Nostalgia In The British Modern Novel, Heather Lynn Lusty

This dissertation focuses on Modern British literary culture and the construction of literary sites of nostalgia through architecture and landscape. The project considers examples from D.H. Lawrence, Virginia Woolf, Ford Madox Ford, and Evelyn Waugh, and examines how these authors employ presentations of architecture in their narratives to portray the irrevocably altered landscape of modernity.

The introduction presents the notion of national consciousness and literature, moving from Lukacs' conception of the historical novel to Victorian art critics John Ruskin and Walter Pater and their writings on national identity and architecture. Twentieth-century European culture responded to the trauma of the Great …

Organization By Form: Applying Systems Theory To Urbanization, Michael Patrick Howe

UNLV Theses, Dissertations, Professional Papers, and Capstones

I have come to believe that the core of our declining physical, mental and community health dwells in the current practice of land use based development. Although today's land use codes began as a legitimate response to protect people's health and welfare it has since devolved into an unsustainable process. The failure of land-use zoning is rooted in an informational disconnect created by the segregation of land into distinct uses while offering generic design standards. Whereas the current mode of land use-based zoning results in an unpredictable physical form, Form-Based Codes foster a connection between the individual to the available …

The Logic Of Movement: Consumption Logistics On The Las Vegas Strip, Robert Dean

UNLV Theses, Dissertations, Professional Papers, and Capstones

The omnipresence of consumption in advanced societies is indisputable; spaces designed to facilitate consumption (or means of consumption) are one aspect of that presence. On the surface, these spaces appear to be quite harmless dreamworlds full of possibilities, but at another level they are highly instrumental, composed of various mechanisms that work to sell commodities through the manipulation of consumer behavior. I argue that consumption spaces express a logic of movement, and a consumption logistics, that is based on the commodity form and relatable to warfare that works to domesticate consumers into the commodity system. I engage in an exploratory …

Examining The Basis For Change In Clark County Non-Conforming Zone Change Process, Was It Needed?, Maria D. Kaseko

UNLV Theses, Dissertations, Professional Papers, and Capstones

This study reviews Clark County's non-conforming zone change process from 1990 to 2002. A non-conforming zone change, sometimes known as a non-conforming zone boundary amendment is a proposed request that is not within the range of residential densities and/or non-residential intensities indicated on the applicable land use plan map, master plan, or concept plan. This research explores and examines two questions raised by the Clark County's new implementation plan, which was approved in April 2003 to amend the non-conforming zone change process. 1) Clark County assumed there was a public perception that non-conforming zone changes were being approved without regard …

A Comparative Analysis Of Southern Nevada Municipalities, And Their Active Participation To Implement Historical Preservation, Rhonda M. Reeves

UNLV Theses, Dissertations, Professional Papers, and Capstones

A comparative analysis of southern Nevada municipalities, and their active participation to implement historical preservation is the foundation of research for this paper. The city of Las Vegas and surrounding municipalities have varying preservation programs in place. The distinctions between the municipalities historic preservation programs foster little protection for the historic site itself in most cases. Historic preservationists are actively bringing to the attention of government the importance of preservation, and are seeking more and more action on the part of the government to implement historic preservation mandates and protection.

The federal government funding for historical preservation within states is …

Crime Prevention Through Environmental Design: An Analysis Of The Boulevard Mall, Kenneth Mac Leod

UNLV Theses, Dissertations, Professional Papers, and Capstones

Many case studies have been published that report a decrease in crime as a result of Crime Prevention Through Environmental Design (CPTED). Although methodologies and results of some studies have been questioned, there is agreement that the designed environment can influence human behavior.

Data in this study were accumulated by the investigation of a local mall. Mall management and head of security reported a decrease in all types of crime after improving and adding security measures for customers and store employees. My hypothesis was the mall provided a high number of CPTED features which would result in a low number …
