Clt Shearwall Dovetail Connection, Alexander Eduardo Esser, August Messano 2018 California Polytechnic State University, San Luis Obispo

Clt Shearwall Dovetail Connection, Alexander Eduardo Esser, August Messano

Architectural Engineering

As cross-laminated timber has become an increasingly popular construction material, its use as a shear wall element has also demanded attention. Primary obstructions to the use of CLT shear walls have been the lack of an economic connection type that does not compromise the structural integrity and has the robustness that CLT shear wall panels deserve. Dovetail connections provide a great option for the connection of CLT shear walls. With more experimentation, the optimal dovetail geometry can be further developed. The small-scale testing done in conjunction with this report proved that very deep pins and tails will result in bearing ...


Evaluation Of Hospital Soundscapes To Improve Patient And Staff Experience, Jay Bliefnick 2018 University of Nebraska

Evaluation Of Hospital Soundscapes To Improve Patient And Staff Experience, Jay Bliefnick

Architectural Engineering -- Dissertations and Student Research

Hospital soundscapes can be difficult environments to assess acoustically due to the continuous activity within units. Routinely, patients perceive these soundscapes poorly when rating their hospital experience on HCAHPS (Hospital Consumer Assessment of Healthcare Providers and Systems) surveys administered after discharge. In addition, hospital staff can be negatively impacted by the acoustical environments in which they work, affecting both performance and job satisfaction. This doctoral research addressed these issues across three phases by collecting acoustical measurements within three individual hospitals, comparing results with provided patient and staff survey information, and conducting laboratory tests of hospital noise perception.

An Investigation Of Daylighting Performance In Sidelit Spaces, Zhe Kong 2018 University of Wisconsin-Milwaukee

An Investigation Of Daylighting Performance In Sidelit Spaces, Zhe Kong

Theses and Dissertations

The positive influence of daylight on people’s work and well-being has been confirmed in many studies. However, excessive daylight causes discomfort glare, which decreases work productivity, impairs occupants’ vision, and may even cause headaches. Substantial studies explored glare by correlating physical lighting measurements and subjective evaluations. With the development of High Dynamic Range (HDR) image techniques, dynamic changes of daylighting distributions can be effectively captured. Consequently, more studies paired HDR image techniques with subject evaluations to explore glare. However, studies merely relying on field measurements are not only time-consuming and labor-intensive but may also disturb occupants. To address these ...

Deep Learning For Automated Image Classification Of Seismic Damage To Built Infrastructure, B. Patterson, G. Leone, Maria Pantoja, Anahid A. Behrouzi 2018 California Polytechnic State University, San Luis Obispo

Deep Learning For Automated Image Classification Of Seismic Damage To Built Infrastructure, B. Patterson, G. Leone, Maria Pantoja, Anahid A. Behrouzi

Architectural Engineering

The amount of structural damage image data produced in the aftermath of an earthquake can be staggering. It is challenging for a few human volunteers to efficiently filter and tag these images with meaningful damage information. The proposed solution is to automate post-earthquake reconnaissance image tagging activities by training a computer algorithm to classify each occurrence of damage per building material and structural member type. The approach is based on deep learning (DL), a subset of machine learning loosely based on the operation of a biologic neural system, which aims to learn and extract accurate representations from large data sets ...

Photo Tagging Tool For Rapid And Detailed Post-Earthquake Structural Damage Identification, Anahid A. Behrouzi, Maria Pantoja

Architectural Engineering

A significant task in earthquake reconnaissance is to conduct rapid and accurate assessments of damage to built infrastructure. This can be accomplished, in part, by analyzing the large volumes of high-resolution image data collected after a seismic event. However, detailed image tagging remains a task for trained human volunteers, which is both time-intensive and error prone. The authors developed a software tool to simplify and standardize the process of assigning damage and structure pairs to sub-regions of images. The goal of the tool is to facilitate the tagging of thousands of images from historic and recent earthquakes to train a ...

Architectural Engineering

Reinforced concrete structural walls are common as the primary lateral load resisting system in modern mid- and high-rise buildings constructed in seismic regions, yet few research programs have investigated the seismic performance of modern, slender walls with nonplanar cross-sectional geometries. Three large-scale, C-shaped wall specimens, designed per ACI 318-08, were tested under uni- and bi-directional loading at the University of Illinois at Urbana-Champaign (UIUC). This paper presents experimental results including the cyclic load-deformation response and measured versus nominal flexural/shear strengths as well as a description of damage sequence. Final failure occurs due to a flexure-tension failure of boundary elements ...

Software Toolset To Enable Image Classification Of Earthquake Damage To Above-Ground Infrastructure, Anahid A. Behrouzi, Maria Pantoja

Architectural Engineering

A critical task after a significant earthquake is determining the extent of damage to infrastructure networks. The decision-making process to dispatch emergency, repair, and in-field reconnaissance teams depends on whether road/railways and bridges are passible. Another concern is the rapid identification and resolution of physical disruptions to large-volume gas and water pipeline systems. After large seismic events, citizens, amateur photographers, and journalists now post thousands of photographs to formal/social media platforms. In the past, these images would have had to be reviewed by trained volunteers or expert engineers to evaluate whether: road/rail ways were significantly impacted by ...
