Lisa Choe, Selvarajah Ramesh, Xu Dai, Matthew Hoehler, Matthew Bundy, Rodney A. Bryant, Brian Story, Anthony R. Chakalis, Artur A. Chernovsky
The National Institute of Standards and Technology is currently conducting a series of large compartment fire tests to investigate the behavior and fire-induced failure mechanisms of the full-scale composite floor systems situated in the two-story and two

Distributed fiber optic measurements of strain and temperature in long-span composite floor beams with simple shear connections subject to compartment fires

May 1, 2021
Author(s)
Yanping Zhu, Matthew Klegseth, Yi Bao, Matthew Hoehler, Lisa Choe, Genda Chen
This study explores an instrumentation strategy using distributed fiber optic sensors to measure strain and temperature through the concrete volume in large-scale structures. Single-mode optical fibers were deployed in three 12.8 m long steel and concrete

Review of Research on the Fire Behavior of Simple Shear Connections

April 8, 2021
Author(s)
Erica Fischer, Rachel Chicchi, Lisa Choe
Previous building fires and research has shown that simple (shear) connections develop large axial force and flexural demands during a fire leading to potential failure of the connections and progressive collapse of a building. These findings have
