Investigation Of Modeling Strategies For Slender Lightly Reinforced Concrete Shear Walls, Jenna Marie Williams, Tracy Destiny Doan

Architectural Engineering: Graduate Reports

A large number of pre-1980’s non-ductile reinforced concrete (RC) structures in California utilizing RC shear walls to resist seismic lateral forces have been identified as deficient by industry practitioners. These non-ductile wall systems are typically lightly reinforced and lack adequate boundary element detailing. Analytical studies suggest these walls are susceptible to brittle, compression-controlled failure modes due to damage from concrete crushing and bar buckling. Furthermore, poor behavior of lightly reinforced concrete walls was observed in many recent earthquakes, for example in Chile (1985), New Zealand (2010/2011) and Mexico (2017). This has generated concern among engineers in high seismic regions around …

Understanding The Impact Of Room Acoustic Conditions On The Kurtosis Levels Of Various Noise Signals, William Spallino

Durham School of Architectural Engineering and Construction: Dissertations, Theses, and Student Research

Impulsive noise can be common in certain occupational and recreational settings, such as manufacturing plants, construction sites, and firing ranges. While many regulations and guidelines for noise exposure exist, their mathematical basis is stronger for continuous noise, and concerns have been raised about the possibility that impulsive noise may be more harmful to people’s hearing than those metrics would let on. Much work has been done on establishing metrics that accurately assess the severity and hearing risk associated with impulsive noise, but the effects of room acoustic conditions on those metrics have been heretofore understudied.

This study calculated room impulse …

Analysis Of Burning Wood In The Transient State And The Application To Structural Design, Roberta Veliz, Kimberly Guzman

Architectural Engineering

Determining the extent of the contribution of exposed timber on compartment fire dynamics in open floor plans is a complex process. Designers traditionally used compartmentalization design methods which create spaces where flashover is likely, given the fuel load and ventilation conditions. However, due to the large geometric dimensions and spread of fuel, fires in open floor plans are more likely to remain as localized or traveling fires. As such, an understanding of not only ignition potential but also flame spread is critical to characterizing the contribution of exposed timber. An integral step in characterizing the potential contribution is through an …
