Thermal response of a composite floor system to the standard fire exposure

December 1, 2019
Author(s)
Dilip K. Banerjee
This paper discusses the development of a finite element model (FEA) of a full-scale composite floor system and application of this model to predict the heating of steel members when exposed to a standard fire during fire resistance experiments. The model

Compartment Fire Experiments on Long-Span Composite-Beams with Simple Shear Connections Part 1: Experiment Design and Beam Behavior at Ambient Temperature

October 22, 2019
Author(s)
Selvarajah Ramesh, Lisa Choe, Mina S. Seif, Matthew Hoehler, William L. Grosshandler, Ana Sauca, Matthew Bundy, William E. Luecke, Yi Bao, Matthew Klegseth, Genda Chen, John Reilly, Branko Glisic
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 was conducted on long-span steel-concrete composite floor beams

Measuring Temperature Distribution in Steel-Concrete Composite Slabs Subjected to Fire Using Brillouin Scattering Based Distributed Fiber Optic Sensors

August 7, 2019
Author(s)
Yi Bao, Matthew Hoehler, Christopher M. Smith, Matthew Bundy, Genda Chen
This study investigates temperature distributions in steel-concrete composite slabs subjected to fire using distributed fiber optic sensors. Several 1.2 m x 0.9 m composite slabs instrumented with telecommunication-grade single-mode fused silica fibers

Influence of Fire on the Lateral Resistance of Cold-Formed Steel Shear Walls – Phase 2: Oriented Strand Board, Strap Braced, and Gypsum-Sheet Steel Composite

March 5, 2019
Author(s)
Matthew S. Hoehler, Blanca Andres Valiente, Matthew F. Bundy
This report presents experimental investigations of the performance of cold-formed steel lateral force-resisting systems (CFS-LRFS) under combinations of simulated earthquake and fire loading. Three types of shear wall systems are investigated: gypsum

Improved Calculation Method for Insulation-based Fire Resistance of Composite Slabs

March 2, 2019
Author(s)
Jian Jiang, Adam L. Pintar, Jonathan M. Weigand, Joseph A. Main, Fahim Sadek
A calculation method for estimating the fire resistance of composite slabs with profiled steel decking according to the thermal insulation criterion is provided in Annex D of Eurocode 4 (EC4). In this study, comparisons between validated high-fidelity

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
