Testing and Modeling of a Cross-Laminated Timber Pier-and-Spandrel Seismic Retrofit Solution for Unreinforced Masonry Buildings

Creator:: Engleson, Renee M.
Abstract:: Cross-laminated timber (CLT) is an attractive building material because it is renewable, promotes fast installation, and possesses a high strength-to-weight ratio. The use of CLT in seismic applications has become increasingly common with the development of post-tensioned CLT rocking wall lateral force resisting systems (LFRS). The CLT pier-and-spandrel system designed,...

The Location of the Neutral Axis in Wood Beams with Multiple Knots

Creator:: Voigt, Levi R.
Abstract:: In a homogenous and isotropic material, the location of the neutral axis coincides with the location of the centroid of the beam. Wood is anisotropic, meaning that it has different properties in different directions. It is also non-homogenous, meaning that the beam exhibits different properties at different locations throughout its...

Development of Ductile System Design Procedures for Steel Slit Panel Frames (SSPF)

Creator:: Fayyadh, Wasan Q.
Abstract:: This dissertation studies the development of the design procedures for Steel Slit Panel Frame (SSPF). The (SSPF) system is a seismic force-resisting system (SFRS) with ductile behavior and good energy dissipation up to 5\% to 7\% lateral drift that acting as seismic fuses. The current design guidelines provided valuable information...

Elevated Temperature Effects on the Shear Performance of a Cross-Laminated Timber (CLT) Wall-to-Floor Bracket Connection

Creator:: Mahr, Kolton J.
Abstract:: Connections in mass timber structural systems dissipate energy and transfer lateral forces from mass timber elements such as shear walls and diaphragms, providing critical load paths. Cross-laminated timber (CLT) is a prominent mass timber material used to manufacture wall and floor assemblies. Fire performance research of CLT walls and floors...

Wind induced torsional fatigue behavior of truss bridge verticals

Creator:: Keller, Philipp
Abstract:: The Astoria-Megler Bridge is a 6.6 kilometer (4.1 mile) long bridge, connecting Oregon and Washington on US 101, with a continuous steel truss main span of 376 m (1232 ft). It is the second longest main span bridge of this type in the world. Due to vortex shedding, some of...

Experimental and analytical investigation of ponding load effects on a steel joist roof system

Creator:: Stark, Duncan
Abstract:: Ponding of water on roof systems leading to collapse causes expensive damage and jeopardizes the life safety of building occupants. Current building codes and design specifications for flat roof systems offer minimal guidance in designing for ponding loads. The present research investigated ponding load effects on a long span, lightweight...

Image rectification tool for evaluation of gusset plate connections in steel truss bridges

Creator:: Nguyen, Quang D.
Abstract:: A methodology was developed to permit rectification and metrification of digital images of steel truss gusset plate connections. The approach will enable rapid and accurate collection of field measurements as compared to traditional methods to enable structural evaluation of gusset plate connections. The program enables the operator to quickly create...

Freeze-thaw durability of reinforced concrete deck girders strengthened for shear with surface-bonded carbon fiber-reinforced polymer

Creator:: Mitchell, Mikal Maxwell
Abstract:: Long-term durability of surface-bonded carbon fiber-reinforced polymer (CFRP) U-wraps for shear strengthening of reinforced concrete (RC) bridge members remains uncertain due to the limited field experience with these materials. This paper provides experimental results from the testing of full-scale RC bridge girder specimens after exposure to prolonged freeze-thaw cycling. CFRP...

Scale effects on reinforced concrete beams strengthened for shear with discrete externally bonded carbon fiber-reinforced polymer U-wraps

Creator:: Dawson, Matthew Ryan
Abstract:: Current ACI design provisions for shear in reinforced concrete (RC) beams strengthened with externally bonded carbon fiber-reinforced polymer (CFRP) U-wraps may not adequately account for the effect of scale. This paper describes tests of 6 geometrically scaled beams to identify possible scale effects of such beams. Results indicated that effective...

Investigation of the behavior of diagonally cracked full-scale CRC deck-girders injected with epoxy resin and subjected to axial tension

Creator:: Smith, Matthew T. (Matthew Todd)
Abstract:: Article 1: Behavior of Epoxy Injected Diagonally Cracked Full-Scale CRC Deck-Girders. Many cast-in place reinforced concrete deck-girder bridges (RCDG) remain in the national inventory and exhibit diagonal cracking. Epoxy injection has been in use for several decades as a method for sealing diagonal cracks, but the effects on girder behavior...
