This paper provides a methodology to perform probabilistic analysis of steel structural members under fire loading. As part developing the methodology, models are proposed for mechanical and thermal properties insulating materials. The two important that significantly influence results (1) yield strength, (2) modulus elasticity. developed include specific heat, conductivity, strain steel; density, conductivity heat A Bayesian statistical approach is used develop using data available in...
Structural risk assessment against fire requires robust material models that take into account the uncertainty in behavior over a range of elevated temperatures. Such probabilistic can directly inform performance-based design procedures for building safety. The objective this research is to quantify uncertainties retained strengths steel and concrete when exposed fire. First, hundreds experimental data points covering temperature 20°C–1,000°C are collected from literature. Then, different...
Resilience of a community after an extreme event depends on the resilience different infrastructure including buildings. There is no well-established approach to characterize and integrate building for community-level applications. This paper investigates how potential functionality measures can be used quantify indexes, results could aggregated set buildings provide indicator entire community. The quantification based repair cost, occupancy level, asset value. An archetype city block with...
Abstract. Following the destructive Lahaina Fire in Hawaii, our team has modeled wind and fire spread processes to understand drivers of this devastating event. The results are good agreement with observations recorded during Extreme winds high variability, a ignition close community, construction characteristics led continued multiple directions. Our suggest that available modeling capabilities can provide vital information guide decision-making emergency response management wildfire events.
Abstract The paper describes the outcomes of analysis a steel braced frame protected with spray-applied fire resistive material and subjected to fires following earthquake (FFE). Nonlinear time-history analyses were performed in order evaluate seismic response. Then, post-earthquake ignitions within selected compartments considered based on damage suffered by structure, which was estimated according inter-storey drift ratio floor acceleration. Natural curves determined means zone models....
Purpose This paper aims to present a literature review on the problem of fire following earthquake (FFE) as potential hazard communities in seismically active regions. The is important work toward resilient that are subject extreme hazards. Design/methodology/approach lists and reviews historical FFE events (20 earthquakes from 7 countries), studies available analytical tools evaluate ignition spread after an earthquake, discusses performance individual buildings under post-earthquake fires...
This paper describes a novel probabilistic fire following earthquake (FFE) framework to develop FFE fragility functions for steel braced frames. In particular, an 8-storey frame, located in high seismic area, was used demonstrate the framework. An algorithm formulated generate scenarios based on damage. Damage caused by expressed terms of inter-storey drift ratio (IDR) and peak floor acceleration (PFA). captured structural non-structural components, such as glazing partition walls. floors...
Background Existing fire spread models focus exclusively on wildland or urban simulation. Aims This study aims at an offline coupling of two to enable a continuous simulation wildfire incident transitioning from into wildland–urban interface (WUI) communities, evaluate the effects wind input results and influence building types patterns. Methods The selected are WRF-Fire, behaviour platform, SWUIFT, model for inside WUI. 2021 Marshall Fire serves as case study. A map fire’s timeline location...
Purpose This paper aims to develop a framework assess the reliability of structures subject fire following an earthquake (FFE) event. The proposed is implemented in one seamless programming environment and used analyze example nine-story steel moment-resisting frame (MRF) under FFE. includes uncertainties load material properties at elevated temperatures evaluates MRF performance based on various limit states. Design/methodology/approach Specifically, this work models density, yield strength...
Design requirements for passive fire protection of steel structures in the United States are primarily based on prescriptive approaches. Yet performance-based design has gained attention recent years its potential to unlock solutions that robust, cost effective, and applicable complex architectural configurations. For example, prior research shown selected secondary beam elements composite floor systems is not necessary due development membrane action concrete slab during fire. In addition,...
