Post-Earthquake Fire Assessment Of Steel Buildings, Yi Li, Rachel Chicchi, Amit H. Varma
Post-Earthquake Fire Assessment Of Steel Buildings, Yi Li, Rachel Chicchi, Amit H. Varma
The Summer Undergraduate Research Fellowship (SURF) Symposium
Resilience of structural systems after hazardous events is a crucial concern of building design. An abundance of research has focused on hazards such as seismic and fire separately. This project conducted a multi-hazard study on steel buildings considering both seismic and fire damage. A literature review of the behavior of steel-framed buildings due to fires after earthquakes, known as post-earthquake fires (PEF), is offered. The new PEF methodology, delivered in this study, starts with creating a three dimensional (3D) model of the examined steel building using the finite element method software, ABAQUS. Next, varying intensities of seismic and fire hazards …
Condition Factor Calibration For Load And Resistance Factor Rating Of Steel Girder Bridges, Joshua Steelman, Pranav M. Shakya
Condition Factor Calibration For Load And Resistance Factor Rating Of Steel Girder Bridges, Joshua Steelman, Pranav M. Shakya
Nebraska Department of Transportation: Research Reports
Load and Resistance Factor Rating (LRFR) is a reliability-based rating procedure complementary to Load and Resistance Factor Design (LRFD). The intent of LRFR is to provide consistent reliability for all bridges regardless of in-situ condition. The primary difference between design and rating is the uncertain severity and location of deterioration, including the potential future loss of strength for an element already evidencing deterioration. Ostensibly, these uncertainties are addressed by applying an additional strength reduction factor: the condition factor, ϕc. Currently, condition factors are nominally correlated to the condition of the member, which can be Good, Fair, or Poor. However, definitions …
