The Blind Side: Using Canned Loading Protocols in Seismic Testing

June 17, 2019
Author(s)
Matthew S. Speicher, Bruce F. Maison
The seismic behavior of a building component (e.g., shear wall) is a fundamental attribute engineers need to assess the earthquake performance of a building. It is no surprise that component behavior is often dependent on the loading history. Repeatedly

Function VoronoiBound

November 30, 2018
Author(s)
Dat Duthinh, Brian M. Phillips
Matlab Function VoronoiBound calculates a Voronoi diagram with inner and outer bounds. This function is useful in defining tributary areas of pressure taps regularly or irregularly placed on the outside surface of a wind tunnel model.

The Lumberton, North Carolina Flood of 2016: A Community Resilience Focused Technical Investigation

October 29, 2018
Author(s)
John W. van de Lindt, Walter G. Peacock, Judith Mitrani-Reiser, Nathanael Rosenheim, Derya Deniz, Maria Dillard, Tori Tomiczek, Maria Koliou, Andrew Graettinger, Patrick Crawford, Kenneth W. Harrison, Andre Barbosa, Jennifer Tobin, Jennifer Helgeson, Lori Peek, Mehrdad Memari, Elaina Sutley, Sara Hamideh, Donghwan Gu, Stephen A. Cauffman, Juan Fung
In early October 2016 Hurricane Matthew crossed North Caroline as a category 1 storm with some areas receiving 15-18 inches of rainfall on already saturated soil. The NIST-funded Center for Risk-Based Community Resilience Planning teamed with researchers

Influence of wind tunnel test duration on wind load factors

August 17, 2018
Author(s)
Dat Duthinh, Adam L. Pintar, Emil Simiu
A methodology is presented for calculating the uncertainty associated with the estimation of peak pressure coefficients from wind tunnel test records of various lengths, and how this uncertainty affects design wind effects. Investigation of time series

Flexural Compression Capacity of Thin Reinforced Concrete Structural Walls

June 25, 2018
Author(s)
Christopher L. Segura, Carlos Arteta, John Wallace
Stability of slender reinforced concrete walls has become an issue of interest for researchers since observations of their performance in recent earthquakes indicated that code compliant walls may be vulnerable to brittle compression failure and rebar

Using FEMA P695 to Interpret ASCE 41 Seismic Performance of Special Moment Frames

June 25, 2018
Author(s)
Matthew S. Speicher, Jazalyn D. Dukes, Kevin K. Wong
ASCE 41 contains methodologies used by practicing engineers for the assessment of existing buildings and the design of new buildings. The National Institute of Standards and Technology recently completed a study investigating the relationship between ASCE

New Connections for Enhancing Robustness of Precast Concrete Frame Structures

February 24, 2018
Author(s)
Travis E. Thonstad, Yihai Bao, Jonathan M. Weigand, Joseph A. Main, Hai S. Lew
A recent experimental and computational study of two precast concrete moment-frame assemblies under a column removal scenario revealed vulnerabilities in the moment connections arising from (a) local bending of reinforcing bars due eccentricity in the

Localized fire tests on steel beams with different end restraints

November 1, 2017
Author(s)
Selvarajah Ramesh, Mina S. Seif, Lisa Choe
Two 6.2-m span I-shaped structural steel beams were tested under combined structural and open flame localized fire loads. Two different support conditions for the beam ends were considered: (i) simple support, and (ii) double-angles bolted to laterally

An experimental study of precast concrete moment frames under a column removal scenario

September 1, 2017
Author(s)
Hai S. Lew, Joseph A. Main, Yihai Bao, Fahim Sadek, Vincent P. Chiarito, Stephen D. Robert, Jorge Torres
This paper presents a full-scale experimental study of two precast concrete moment-frame assemblies, each comprising three columns and two beams. The assemblies represented portions of seismically designed perimeter moment frames from two 10-story

Loading Protocols for ASCE 41 Backbone Curves

November 1, 2016
Author(s)
Bruce F. Maison, Matthew Speicher
ASCE 41-13 is an industry standard for seismic evaluation and retrofit of existing buildings. Alternative component modeling and acceptance criteria are based on a backbone curve constructed from an envelope of component hysteresis loops derived via
