An Investigation Of The Influence Of Diaphragm Flexibility On Building Design Through A Comparison Of Forced Vibration Testing And Computational Analysis, Blake Alan Roskelley
An Investigation Of The Influence Of Diaphragm Flexibility On Building Design Through A Comparison Of Forced Vibration Testing And Computational Analysis, Blake Alan Roskelley
Master's Theses
An assessment of the validity of idealizing a concrete diaphragm as rigid was performed through the modal analysis of three existing buildings. Modal analysis was performed both by physical experimentation and computational analysis. Experimental determination of the mode shapes shows that two of the three buildings’ diaphragms exhibited flexible behavior. The experimental results were compared to computational analysis results and were shown to be similar, confirming that that the two building diaphragms are not rigid. As a standard, diaphragms with aspect ratios less than three are permitted to be idealized as rigid per ASCE 7-05. To determine the effect of …
An Exploratory Study On Energy Consumption Of Energy Star And Non-Energy Star Homes, Prajakta Kulkarni
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 …
Evaluation Of Safety Impact Of Access Management In Urban Areas, Xuecai Xu
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 …
Bus On Shoulder: Local Assessment Of Shoulder Transit Lane For Regional Buses In San Luis Obispo County, Jessica R. Berry
Bus On Shoulder: Local Assessment Of Shoulder Transit Lane For Regional Buses In San Luis Obispo County, Jessica R. Berry
Master's Theses
The study looks at the applicability of integrating a Bus Only Shoulder (BOS) into the intermittently congested segment of US 101 in southern San Luis Obispo County. Policy, infrastructure and implementing criteria derived from case studies in Minnesota, Florida and California (San Diego) and the 2007 California Decision Document on BOS are applied to conditions in the region. One measure of performance, time savings, is projected to 2025 to determine the value of integrating the program by that horizon year. Given the substantial potential for time savings in that future year, recommendations are made to create the appropriate policy and …
City Of Davis Greenbelt Master Plan, Brandon Haydu
City Of Davis Greenbelt Master Plan, Brandon Haydu
Master's Theses
The City of Davis is currently updating its Parks and Recreation Facilities Master Plan. During the update, greenbelts were identified as a highly used and desired facility. This Greenbelt Master Plan serves as a plan focused on the opportunities greenbelts can provide as recreational and transportation facilities. This report has analyzed community feedback, greenbelt coverage, greenbelt capacity, and existing local, state, and federal design guidelines. The final plan is a set of goals, objectives, policies, and programs, along with a greenbelt map, which is aimed at improving the greenbelt infrastructure in Davis through the year 2020.
Identification Of Physical Changes To A Steel Frame, Daniel Eric Means
Identification Of Physical Changes To A Steel Frame, Daniel Eric Means
Master's Theses
The thesis utilized physical testing and computer modeling to determine the feasibility of identifying a change to the mass or stiffness of a steel frame. Physical testing was performed using an accelerometer, linear shaker, and arbitrary function generator. Two methods of laboratory testing were developed: ambient vibration testing (AVT) and forced vibration testing (FVT). AVT was able to preliminarily identify the natural frequencies and mode shapes of the frame. FVT was able to precisely identify four distinct natural frequencies, mode shapes, and damping ratios. The baseline frame then underwent two physical changes: the addition of mass to its roof, and …
A Study Of The Economical Feasibility Of Installing Heating, Ventilation, And Air-Conditioning Condensate Recovery System, Rafid M. Kully
A Study Of The Economical Feasibility Of Installing Heating, Ventilation, And Air-Conditioning Condensate Recovery System, Rafid M. Kully
Theses
The objective of this study is to establish a guide line or an analytical frame work to predetermine the economic benefits associated with the installation of Heating, Ventilation, and Air-Conditioning (HVAC) condensate recovery systems to capture the air-handler’s condensate water and use it as makeup water for the cooling tower. Some factors should be considered such as; the location, building operation, amount of outside air required, type of energy recovery system, and indoor conditions setup. Experimental data was used from Emory University in Georgia, where a condensate recovery system was installed and the condensate water from four air-handler units at …
