Improved Video Capture for Severe Fire Environments

June 17, 2020
Author(s)
Matthew S. Hoehler
This short presentation shows the functional concept, Do It Yourself (DIY) construction details and select deployment examples for the current (May 2020) water-cooled live streaming camera systems (2D cameras) used to capture video footage in severe fires

Experimental investigation of structural steel beams subjected to localized fire

May 29, 2020
Author(s)
Selvarajah Ramesh, Lisa Y. Choe, Chao Zhang
This paper presents an experimental behavior of unprotected W16 × 26 steel beams subjected to localized fire. Beam specimens were either simply supported or connected to steel columns via all bolted double angle connections. Two test fires, steady or

Behavior and Limit States of Long-Span Composite Floor Beams with Simple Shear Connections subject to Compartment Fires: Experimental Evaluation

Lisa Y. Choe, Selvarajah Ramesh, William L. Grosshandler, Matthew S. Hoehler, Mina S. Seif, John L. Gross, Matthew F. Bundy
This paper presents the results of compartment fire experiments on four 12.8 m long composite floor beams with various end support conditions. Specimens were constructed as partially- composite beams, consisting of W18x35 steel beams and 83 mm thick

Reduced-Order Modeling of Composite Floor Slabs in Fire. I: Heat-Transfer Analysis

March 18, 2020
Author(s)
Jian Jiang, Joseph Main, Jonathan Weigand, Fahim H. Sadek
This paper presents a reduced-order numerical modeling approach for the analysis of heat transfer in composite floor slabs with profiled steel decking exposed to fire effects. This approach represents the thick and thin portions of a composite slab with

The NIST 20 MW Calorimetry Measurement System for Large-Fire Research

December 26, 2019
Author(s)
Rodney A. Bryant, Matthew F. Bundy
The National Fire Research Laboratory is a unique large-fire research facility; able to characterize the response of full-scale building systems to realistic mechanical loading and fire. The facility maintains an infrastructure of measurements necessary

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
