Review of Fiber Optic Sensors for Structural Fire Engineering

February 20, 2019
Author(s)
Yi Bao, Ying Huang, Matthew Hoehler, Genda Chen
Reliable and accurate measurements of temperature and strain in structures subjected to fire can be difficult to obtain using traditional sensing technologies based on electrical signals. Fiber optic sensors, which are based on light signals, solve many of

Experimental Study of Fire-Induced-Delamination of Cross Laminated Timber

January 1, 2019
Author(s)
Daniel Brandon, Birgit Ostman, Joseph Su, Amanda Kimball, Matthew Hoehler
Cross Laminated Timber (CLT) is increasingly used as a structural material for tall buildings, due to its structural properties and low carbon footprint. CLT is a mass timber product, which is made by crosswise gluing layers of timber lamellae. Recent

Influence of Fire on the Shear Capacity of Cold-Formed Steel Framed Shear Walls

November 7, 2018
Author(s)
Matthew S. Hoehler, Blanca Andres Valiente
This paper presents experimental investigations of the performance of common lateral force- resisting systems used in cold-formed steel construction under sequential thermal (fire) and mechanical (earthquake) loading. Wall specimens with gypsum-sheet steel

A Novel Application of Silicone-Based Flame-Retardant Adhesive in Plywood

September 11, 2018
Author(s)
Mauro Zammarano, John R. Shields, Elizabeth D. Knowlton, Ickchan Kim, Matthew S. Hoehler
A silicone-based elastomer filled with vinyl-silane treated aluminum hydroxide was used as a flame- retardant adhesive for plywood, as a replacement for a conventional polyurethane-based adhesive. The shear strength and fire performance of such a silicone

Imaging Through Fire Using Narrow-Spectrum Illumination

July 23, 2018
Author(s)
Christopher M. Smith, Matthew Hoehler
This paper demonstrates a simple method to enhance visibility through clean-burning flames that allows new opportunities to perform optical metrology in fire research. The method combines narrow-spectrum, blue illumination and matched optical filters to

Influence of Fire on the Seismic Shear Capacity of Cold-Formed Steel Shear Walls

June 25, 2018
Author(s)
Blanca Andres Valiente, Matthew Hoehler
Lightweight construction using cold-formed steel (CFS) stud represent roughly 20 % of the multi-story nonresidential building market in the United States. During an earthquake, these buildings rely on the performance of their lateral force-resisting system

Experimental Fire-Simulator For Post-Flashover Compartment Fires

June 6, 2018
Author(s)
Daniel Brandon, Joachim Schmid, Joseph Su, Matthew Hoehler, Birgit Ostman, Amanda Kimball
The number of tall timber buildings around the world is rapidly increasing as a result of changes in regulations and the development of new engineered timber products. However, due to the combustibility of timber, the fire safety of tall timber buildings

FIRE PERFORMANCE OF LONG-SPAN COMPOSITE BEAMS WITH GRAVITY CONNECTIONS

June 6, 2018
Author(s)
Lisa Y. Choe, Selvarajah Ramesh, Mina S. Seif, Matthew S. Hoehler, William L. Grosshandler, John L. Gross, Matthew F. Bundy
Prescriptive fire-resistance ratings for structural components provide limited insight into the system-level performance of steel-concrete composite structures in fire. Specifically, long- span composite beam assemblies exposed to fire have vulnerabilities

Application of Digital Image Correlation to Structures in Fire

June 4, 2018
Author(s)
Christopher M. Smith, Matthew Hoehler
The behavior of engineering structures in fire is commonly studied through large-scale experiments. However, temperature-varying material properties, spatially-varying thermal loading and complicated structure geometries result in these structures

Behavior of Steel-Sheathed Shear Walls Subjected to Seismic and Fire Loads

August 7, 2017
Author(s)
Matthew S. Hoehler, Christopher M. Smith, Tara C. Hutchinson, Xiang Wang, Brian J. Meacham, Praveen Kamath
A series of tests was conducted on six 2.7 m × 3.7 m shear wall specimens consisting of cold- formed steel framing sheathed on one side with sheet steel adhered to gypsum board and on the opposite side with plain gypsum board. The specimens were subjected

Performance of Composite Beams in Fire: Pre-test Analysis of Full-scale Experiments

July 23, 2017
Author(s)
Joseph Main, Fahim H. Sadek, Jonathan Weigand, Jian Jiang, Lisa Choe, Selvarajah Ramesh, Matthew Hoehler, John L. Gross
This paper presents results from pre-test analysis of a full-scale 42 ft (12.8 m) span composite beam with bolted angle connections, under uniform gravity loading simulated using six equally spaced concentrated loads, and subjected to a 4000 kW compartment

Behavior of post-installed anchors tested by stepwise increasing cyclic crack protocols

May 1, 2017
Author(s)
Christoph Mahrenholtz, Rolf Eligehausen, Tara C. Hutchinson, Matthew Hoehler
The American Concrete Institute (ACI) standards for qualification of post-installed concrete anchors (ACI 355.2 and ACI 355.4) include a nonseismic crack movement test characterized by a large number of small-amplitude crack cycles. This paper investigates
