The Fundamental Behavior of CLT Floor-to-Wall Connections in Fire

Creator:: Redus, James Aaron
Abstract:: This thesis focuses on the fundamental behavior of CLT floor-to-wall connections during a fire. Cross-laminated timber (CLT) panelized structures rely on floor-to-wall connections for the load path and stability of the structure. Additionally, the fire performance of these connections is critical to prevent horizontal or vertical fire spread within these...

Modular Cross Laminated Timber Structures Using Underutilized Ponderosa Pine

Creator:: Bhandari, Sujit
Abstract:: Conflicts and disasters displace millions of populations worldwide. There is a need for rapid and affordable housing to cater to the needs of the displaced and unhoused population. Experience from previous post-disaster responses shows that temporary housing should be rapidly deployable, planned for months to years, and should be environmentally...

Cross-Laminated Timber-Concrete Composite Floor Systems for Tall Building Design

Creator:: Morrell, Ian
Abstract:: With growing interest in mass timber, especially mass timber panels (MTP), there has been a need to better understand their structural properties. One of the most versatile uses for MTP are as floor systems. Under new code provisions, these floors can be utilized in new and taller building types, but...

In-plane Creep Behavior of Cross-laminated Timber and Mass Plywood Panels: A Methodology to Evaluate the Long-term Performance of Post-Tensioned Mass Timber Walls

Creator:: Longman, Ryan P.
Abstract:: Post-tensioned (PT) self-centering shear walls were designed to reduce structural damage from seismic activity. However, these lateral force resistant systems experience post-tension loss negatively affecting the re-centering capability due to delayed deformations experienced by engineered wood products over time. The long-term mechanical response of mass-timber panels to in-plane PT loads...

Structural Design and Testing of Mass Timber Concrete Composite Floor Solutions with Acoustic Interlayers

Creator:: Srivastava, Mohit Raja
Abstract:: Timber-concrete composite (TCC) solutions originated in the early twentieth century. There has been a renewed interest in TCC solutions in modern mass timber buildings, especially for floor systems. However due to lack of data, design standards, and code acceptance, TCC solutions require that new mass timber solutions be tested, and...

Identifying and prioritizing research gaps for the incorporation of fires in life cycle analysis of structures: A Delphi survey of international experts

Creator:: Thorp, Tiana Noelani
Abstract:: Civil engineers are aware of the impacts of structures on the global environment but the environmental impacts of a fire within these structures remains unknown. Fires present a unique hazard as it is difficult to predict the probability of the occurrence and the intensity. Traditional methods to identify the environmental...

Gravity and Wind Load Path Analysis of a Light-Frame and a Traditional Timber Frame Building

Creator:: Malone, Brian P., Miller, Thomas H., and Gupta, Rakesh
Abstract:: The objective of this study was to compare structural load path and system behavior of a light-frame (LF) and a timber frame (TF) structure. This load path analysis is part of a broader research effort that compares LF to TF residential structures. Structural analysis software was used to create a...

Effects of Roof Pitch and Gypsum Ceilings on the Behavior of Wood Roof Diaphragms

Creator:: Kirkham, William J., Gupta, Rakesh, and Miller, Thomas H.
Abstract:: Ten full-size (3.7×4.9m) plywood roof diaphragms were constructed using metal-plate-connected (MPC) common and hip wood trusses or joists, typical of single-family dwelling (SFD) construction. The specimens included three gable roof slopes of 33, 67, and 100%, a hip roof of 33% slope, and a flat roof, with a horizontal bottom...

Performance of partially and fully anchored wood-frame shear walls under earthquake loads

Creator:: Seaders, Peter, Miller, Thomas H., and Gupta, Rakesh
Abstract:: The objectives of this study were to evaluate the performance of wood-frame shear walls under monotonic, cyclic, and earthquake loads by: 1) comparing performance under each loading protocol; 2) evaluating effects of anchorage; and 3) eval-uating performance qualitatively and quantitatively with respect to code-deﬁned performance measures. Tests were conducted on...

Practical Analysis for Horizontal Diaphragm Design of Wood-Frame Single-Family Dwellings

Creator:: Kirkham, William J., Miller, Thomas H., and Gupta, Rakesh
Abstract:: Seismic design of wood-frame single-family dwellings’ (WFSFD) lateral force–resisting systems requires determination of the stiffness of horizontal diaphragms and shearwalls. During design, sizes and locations of shearwall openings are often changed, altering shearwall stiffness and loads and requiring a significant redesign effort. Rigid and tributary area method analyses are examined...

Thermal Degradation of Lateral Yield Strength of Nailed Wood Connections

Creator:: Sinha, Arijit, Gupta, Rakesh, and Nairn, John A.
Abstract:: This study investigated the effect of exposure to elevated temperature on the yield strength of single-shear nail connections when subjected to lateral loading. Solid sawn lumber and laminated veneer lumber were used as framing members and two different thicknesses of both oriented strand board and plywood were used as the...

A procedure for rapid visual screening for seismic safety of wood-frame dwellings with plan irregularity

Creator:: Lucksiri, Kraisorn, Miller, Thomas H., Gupta, Rakesh, Pei, Shiling, and van de Lindt, John W.
Abstract:: This paper highlights the development of a rapid visual screening (RVS) tool to quickly identify, inventory, and rank residential buildings that are potentially seismically hazardous, focusing on single-family, wood-frame dwellings with plan irregularity. The SAPWood software was used to perform a series of nonlinear time-history analyses for 480 representative models,...
