1. High-temperature material constitutive models for structural-fire analysis
Published: 6/8/2016
Authors: Chao Zhang, Lisa Yong yae Choe, John L Gross
Abstract: The applicability of three steel constitutive models was evaluated using finite-element analyses and various member capacity equations. Three different high-temperature stress-strain models were compared: the model recently developed by the Natio ...

2. The performance of structural steel beams subject to a localized fire
Published: 6/8/2016
Authors: Lisa Yong yae Choe, Selvarajah Ramesh, Chao Zhang, John L Gross
Abstract: This paper presents the results from the open flame, localized fire tests conducted on the 6.17-m long, simply supported W16×26 beam specimens. The cross sections at midspan (i.e. expected plastic hinge zone) of the beam specimen directly exposed ...

3. Temperature-Dependent Material Modeling for Structural Steels: Formulation and Application
Series: Technical Note (NIST TN)
Report Number: 1907
Published: 4/15/2016
Authors: Mina Samir Seif, William E Luecke, Lisa Yong yae Choe, Joseph A Main, Joseph David McColskey, Chao Zhang, Jonathan M Weigand, John L Gross, Fahim Sadek
Abstract: This report presents the formulation and application of a newly developed temperature-dependent material model for structural steels. First it presents a model for computing the stress-strain behavior of structural steel for conditions appropriat ...

4. INFLUENCE OF MATERIAL MODELS ON PREDICTING THE FIRE BEHAVIOR OF STEEL COLUMNS
Published: 2/19/2016
Authors: Lisa Yong yae Choe, Chao Zhang, William E Luecke, John L Gross, Amit Varma
Abstract: Finite-element (FE) analysis was used to compare the high-temperature responses of steel columns with two different stress‹strain models: the Eurocode 3 model and the model proposed by National Institute of Standards and Technology (NIST). The compar ...

5. International R&D Roadmap for Fire Resistance of Structures Summary of NIST/CIB Workshop
Series: Special Publication (NIST SP)
Report Number: 1188
Published: 6/11/2015
Authors: Jiann C Yang, Matthew F Bundy, John L Gross, Anthony P Hamins, Fahim Sadek, Anand Raghunathan
Abstract: This report summarizes the results of the global meeting to develop the International R&D Roadmap for Fire Resistance of Structures (the Roadmap) held May 21‹22, 2014, in Gaithersburg, Maryland. The workshop was sponsored by the National Instit ...

6. Behavior of Unrestrained and Restrained Steel Columns Adjacent to Localized Fire
Published: 12/12/2014
Authors: Chao Zhang, John L Gross, Therese P McAllister, Guo-Qiang Li
Abstract: Steel columns may be exposed to thermal radiation from localized burning of a fire source nearby. Current structural fire design methods are based on uniform heating and, therefore, uniform temperature conditions, and no practicable methods are p ...

7. A COMPARISON OF TWO TEMPERATURE-DEPENDENT STRESS-STRAIN MODELS FOR STRUCTURAL STEEL UNDER TRANSIENT HEATING CONDITION
Published: 6/11/2014
Authors: Lisa Yong yae Choe, William E Luecke, John L Gross
Abstract: The finite-element method (FEM) requires accurate constitutive models for predicting the behaviour of steel components, structural members, or systems subjected to fire. As part of the World Trade Centre collapse investigation, the National Institu ...

8. BEHAVIOR OF STEEL COMPONENTS SUBJECTED TO LOCALIZED FIRE
Published: 6/11/2014
Authors: Chao Zhang, John L Gross, Lisa Yong yae Choe
Abstract: Recent numerical studies on the behavior of steel components subjected to a localized fire are presented. Sequentially coupled thermo-mechanical simulations were conducted to predict the steel temperature distribution, the deformation mode and fa ...

9. Structural Design for Disaster Resilience
Published: 10/28/2013
Authors: Fahim Sadek, Joseph A Main, John L Gross, Therese P McAllister
Abstract: This paper presents a brief overview of research at the National Institute of Standards and Technology (NIST) on disaster resilience of buildings, infrastructure, and communities, including component programs and projects. NIST‰s efforts aim at deve ...

10. Lateral torsional buckling of steel W-beams subjected to localized fires
Published: 9/1/2013
Authors: Chao Zhang, John L Gross, Therese P McAllister
Abstract: Current design approaches to assess the lateral torsional buckling capacity of steel beams in fire are based on the assumption of uniform steel temperature. This paper investigates the effect of temperature gradients on the lateral torsional buckling ...
