Activities and Lessons Learned from ACI Committee 133 - Disaster Reconnaissance

September 13, 2020
Author(s)
Lucas A. Laughery, Aishwarya Y. Puranam, Christopher Segura, Anahid A. Behrouzi
ACI Committee 133 Disaster Reconnaissance was established with the mission of reporting on the effects of major disasters on reinforced concrete (RC) structures. ACI 133 members monitor natural and manmade disasters worldwide to identify events that affect

Loading Protocols and Backbone Curves: U.S. and Japan Perspectives

September 13, 2020
Author(s)
Bruce F. Maison, Kazuhiko Kasai, Matthew Speicher
With the gaining popularity of performance-based engineering, it is essential to have reliable estimates of component (e.g., steel beam or column) performance under actual earthquake loading demands. In the United States, a component backbone curve

Seismic Stability Assessment of Steel Moment Frames and Implications for Design

September 13, 2020
Author(s)
Larry Fahnestock, Shitao Shi, Matthew Speicher
Although it is clear that a building must be capable of carrying gravity loads while developing large inelastic deformations and associated lateral displacements during a large earthquake, achieving this performance objective in day-to-day practice still

Modern reassessment of the Citicorp Building design wind loads

June 15, 2020
Author(s)
Dat Duthinh
Following structural engineering practice of the 1970s, engineers designed the Citicorp Building for the action of wind in each of the structure’s principal axes. One problem they faced was how to determine design values by combining simultaneous wind

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

Collapse Risk of Steel Special Moment Frames per FEMA P695

February 5, 2020
Author(s)
Matthew S. Speicher, Jazalyn D. Dukes, Kevin K. Wong
The American Society of Civil Engineers (ASCE) performance-based seismic design standard, ASCE 41, contains methodologies used by practicing engineers to assess existing buildings and to design new buildings. In 2015, the National Institute of Standards
