Structural Design for Disaster Resilience

October 28, 2013
Author(s)
Fahim H. Sadek, Joseph Main, John L. Gross, Therese P. McAllister
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 developing

Fatigue Crack Growth Modeling of Pipeline Steels in High Pressure Gaseous Hydrogen

October 21, 2013
Author(s)
Robert L. Amaro, Elizabeth S. Drexler, Andrew J. Slifka
Hydrogen will likely play a key role in a future clean energy economy. However, fundamental understanding of the deleterious effects of hydrogen on the fatigue and fracture properties of pipeline steels is lacking. Furthermore, engineering tools for design

Modeling and Analysis of Single-Plate Shear Connections Under Column Loss

May 8, 2013
Author(s)
Joseph A. Main, Fahim Sadek
This paper presents a computational assessment of the behavior of single-plate shear (“shear tab”) connections in gravity frames under column loss scenarios. Two-span beam assemblies are considered under pushdown loading of the unsupported center column

Discussion of Review of Methods to Assess, Design for, and Mitigate Multiple Hazards by Yue Li, Aakash Ahuja, and Jamie E. Padgett (J. Performance of Constructed Facilities, 26 104-117)

March 1, 2013
Author(s)
Dat Duthinh, Long T. Phan, Emil Simiu
The authors have performed a useful service by providing a broad perspective on multi-hazard engineering. The discussers would like to complement that perspective by noting two results of practical significance in the context of design for multiple hazards

Robustness of Steel Gravity Frame Systems with Single-Plate Shear Connections

February 27, 2013
Author(s)
Joseph A. Main, Fahim Sadek
This report presents a computational assessment of the performance of steel gravity framing systems with single-plate shear (“shear tab”) connections and composite floor slabs under column loss scenarios. The computational assessment uses a reduced

Modeling of Reinforced Concrete Assemblies under a Column Removal Scenario

November 8, 2012
Author(s)
Yihai Bao, Hai S. Lew, Sashi K. Kunnath
This paper presents a computational investigation of two reinforced concrete beam-column assemblies, each comprising three columns and two beams, subjected to monotonically increasing vertical displacement of the unsupported center column simulating a

Performance of Steel Moment Connections under a Column Removal Scenario. I: Experiments

April 3, 2012
Author(s)
Hai S. Lew, Joseph A. Main, Stephen D. Robert, Fahim Sadek, Vincent Chiarito
This paper presents an experimental study of two full-scale steel beam-column assemblies, each comprising three columns and two beams, to (1) define their response characteristics under a column removal scenario, including the capacity of the beams and

Performance of Steel Moment Connections under a Column Removal Scenario. II: Analysis

April 3, 2012
Author(s)
Fahim H. Sadek, Joseph Main, Hai S. Lew, Sherif El-Tawil
This paper presents a computational investigation of the response of steel beam-column assemblies with moment connections under monotonic loading conditions simulating a column removal scenario. Two beam-column assemblies are analyzed, which incorporate (1
