Wood Diaphragm Deflections. Part I: Generalizing Standard Equations Using Mechanicsbased Derivations For Panel Construction, John W. Lawson, Scott Breneman, Marco Lo Ricco

Architectural Engineering

Horizontal wood diaphragm systems, whether decked with conventional or mass timber panels, transfer wind and seismic loads to vertical elements of the lateral force-resisting system (LFRS), in flexible, rigid, or semi-rigid fashion. Characterizing and calculating the resulting diaphragm deflections determines the distribution of forces to critically loaded components and a significant portion of lateral building translations and rotations. Deflection equations for sheathed wood structural panel (WSP) diaphragms are well established in U.S. design standards in a 4-term expression that models flexural, shear, and fastener-slip deformations and its full derivation using principles of mechanics is provided herein. Derivations of similar equations …

Wood Diaphragm Deflections. Part Ii: Implementing A Unified Approach For Current Clt And Wsp Practice, John Lawson

Architectural Engineering

Horizontal wood diaphragm systems, whether decked with conventional or mass timber panels, transfer wind and seismic loads to vertical elements of the lateral force-resisting system (LFRS), in flexible, rigid, or semi-rigid fashion. Characterizing and calculating the resulting diaphragm deflections determines the distribution of forces to critically loaded components and a significant portion of lateral building translations and rotations. Deflection equations for sheathed wood structural panel (WSP) diaphragms are well established in U.S. design standards in a 4-term expression that models flexural, shear, and fastener-slip deformations, but similar equations for cross-laminated timber (CLT) diaphragms have yet to unfold, despite growing industry …

A Case For Educational Communication On Sustainable Stormwater Management Sites Using Interpretive Methods: Applications For Utah State University, Lilian Taft

All Graduate Plan B and other Reports

Humans are increasingly urbanizing landscapes, lowering the land’s ability to infiltrate stormwater, increasing surface water runoff. This, combined with decreasing water availability in the Intermountain West, produces the issue of sustainable stormwater management. Professionals are moving toward green stormwater infrastructure (GSI), but public is often not aware of stormwater’s impacts on natural environments or what the purpose of GSI is. Stormwater management design techniques are evolving to use visible, sustainable methods celebrating stormwater, rather than treating the valuable resource as a disposable nuisance, channeling it underground and out of sight. Artful Rainwater Design (ARD), a technique coined by Stuart Echols …

Circadian Rhythm In Design: An Application Of Circadian Rhythmic Elements To The Ridgedale Mill, Jesse Hayes

Honors Theses

Through the study of the phases of circadian rhythm and by applying associated environmental cues, can a building further promote health and well-being through design? This study argues that by applying design elements associated with each phase of the circadian rhythmic cycle to a built environment, overall human health and well-being are increased. Research shows, that if the circadian rhythm is disrupted “metabolic syndrome and obesity, premature aging, diabetes, cardiac arrhythmias, immune deficiencies, hypertension, and abnormal sleep cycles develop” (Brainard, 2015, p. 1). Furthermore, if the circadian rhythm is promoted through environmental cues it benefits the body by supporting the …

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Wood-frame structures are used in almost 90% of residential buildings in the United States. It is thus imperative to rapidly and accurately assess the damage of wood-frame structures in the wake of an earthquake event. This study aims to develop a machine-learning-based seismic classifier for a portfolio of 6,113 wood-frame structures near the New Madrid Seismic Zone (NMSZ) in which synthesized ground motions are adopted to characterize potential earthquakes. This seismic classifier, based on a multilayer perceptron (MLP), is compared with existing fragility curves developed for the same wood-frame buildings near the NMSZ. This comparative study indicates that the MLP …

A Spike-Shaped Anchorage For Steel Reinforced Polymer (Srp)-Strengthened Concrete Structures, Xingxing Zou, Keenan L. Mcburney, Lesley H. Sneed

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Steel reinforced polymer (SRP) composite has recently emerged as an effective and economical solution for strengthening of reinforced concrete (RC) structures. Premature debonding failure of unanchored SRP at low load levels generally governs the performance of RC structures strengthened with externally bonded SRP. Therefore, a novel yet simple spike-shaped anchorage system was proposed in this study to prevent the debonding failure of SRP and to improve the interfacial shear capacity. Experimental investigation through single-lap shear tests of SRP-concrete joints showed that the anchorage system changed the failure mode from composite debonding to fiber rupture. In addition, the anchorage system substantially …

Coliving: Bringing Social Spaces Back Offline, Helen Dymek

Bachelor of Architecture Theses - 5th Year

The way in which we construct our built environment defines how our community will engage with one another. Social spaces are the key to creating a healthy community. However, today, we are in crisis. In a society which is built on the pillars of freedom and independence, our social spaces are dying out. Social isolation is on the rise, a problem only accelerated by the recent pandemic. Today, many Americans (and much of the world) seek social connection through a screen. Instead of getting to know our neighbors, we spend more time watching videos of or talking to people who …
