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

Fire Safety Challenges of Tall Wood Buildings: Large-Scale Cross Laminated Timber Compartment Fire Tests

June 6, 2018

Author(s)

Matthew S. Hoehler, Joseph Su, Pier-Simon Lafrance, Matthew F. Bundy, Amanda Kimball, Daniel Brandon, Birgit Ostman

This study investigates the contribution of cross laminated timber (CLT) building elements to compartment fires. Six compartments (9.1 m long x 4.6 m wide x 2.7 m high) were constructed using 175-mm thick 5 ply CLT structural panels and fire tested using

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

June 6, 2018

Author(s)

Matthew S. Hoehler, Blanca Andres Valiente

This paper discusses experimental investigations of the influence of real fires on the lateral load-carrying capacity of steel-sheathed cold-formed steel framed shear walls. The completed Phase 1 tests showed an unexpected and important example of

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

Design and Construction of Long-Span Composite Beam Specimens for Large Structural-Fire Tests

May 10, 2018

Author(s)

Selvarajah Ramesh, Lisa Choe, Matthew Hoehler, William L. Grosshandler, John L. Gross

A series of experiments is being conducted on five 12.8 m long composite floor beams at the newly-commissioned National Fire Research Laboratory at the National Institute of Standards and Technology. The test beams were designed according to current U.S

Experimental Study on Long-Span Composite Floor Beams Subject to Fire: Baseline Data at Ambient Temperature

April 17, 2018

Author(s)

Lisa Y. Choe, Selvarajah Ramesh, Matthew S. Hoehler, John L. Gross

The National Institute of Standards and Technology recently expanded its large-scale structural-fire testing capabilities in the National Fire Research Laboratory. A landmark test series is being conducted on long-span steel-concrete composite floor beams

Fire Safety Challenges of Tall Wood Buildings - Phase 2: Task 3 - Cross Laminated Timber Compartment Fire Tests

February 14, 2018

Author(s)

Joseph Su, Pier-Simon Lafrance, Matthew Hoehler, Matthew Bundy

This study quantifies the contribution of cross laminated timber (CLT) building elements to compartment fires and characterizes the effect of gypsum board on delaying or preventing involvement of the CLT in the fire under varied ventilation conditions. Six

Development and validation of European guidelines for seismic qualification of post-installed anchors

October 1, 2017

Author(s)

Philipp Mahrenholtz, Richard Wood, Rolf Eligehausen, Tara C. Hutchinson, Matthew Hoehler

This paper presents the technical background for seismic qualification procedures for post installed anchors in the European Technical Approval Guideline (ETAG 001) seismic annex issued in 2013. We discuss requirements for a comprehensive guideline and

Temperature measurement and damage detection in concrete beams exposed to fire using PPP-BOTDA based fiber optic sensors Optic Sensors

September 18, 2017

Author(s)

Yi Bao, Matthew Hoehler, Fujian Tang, Christopher M. Smith, Matthew Bundy, Genda Chen

In this study, Brillouin scattering-based distributed fiber optic sensor is implemented to measure temperature distributions and detect cracks in concrete structures subjected to fire for the first time. A telecommunication-grade optical fiber is

Large-Scale, Real-Fire Structural Testing: A unique testing and metrology challenge

September 8, 2017

Author(s)

Matthew S. Hoehler

This talk will address large-scale experiments of structures subject to real fires and the challenges associated with measurement of structural performance in this environment. While dramatic structural collapse during a fire is thankfully rare, our

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
