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
