Item Open Access Heritage Considerations in Fire Safety Engineering(2021-11-15) Harun, Georgette Bowering; Gales, John A.The objective is to initiate a framework of guidance for fire safety engineering and heritage conservation, where there is a dearth between the disciplines. The human factor of emergency egress is evaluated through the pedestrian modelling of a case study heritage cultural center that underwent many interventions. Their effectiveness on egress is evaluated and found to have a 17.7% improvement on total egress time. The residual properties of heritage timber and masonry after fire are also evaluated. The timber testing considers the effect of existing radial cracks on charring of timber through pool fire exposure and cone calorimetry. The radial cracks were found to increase char depth by 64% and 29% for both tests respectively. The masonry testing compares compressive strengths of heritage and contemporary masonry units after 800C furnace heating. Provisional results show no significant reduction in strength and a framework for testing heritage masonry materials is presented.Item Open Access Performance Assessment and Retrofit Strategies for Unreinforced Masonry Structures(2024-03-16) Pezeshki, Mina; Pantazopoulou, StavroulaThis research project provides a detailed investigation into the seismic assessment of Unreinforced Masonry (URM) heritage structures, emphasizing their cultural and historical importance and vulnerability to earthquakes. It focuses on advanced seismic evaluation methods, including 3-D finite element modeling, to address specific challenges such as the unique characteristics of these buildings, like distributed stiffness and mass, and the absence of diaphragm action. The project aims to bridge knowledge gaps in the dynamic, nonlinear behavior of URM structures during seismic events, and involves comparative evaluation of different computational modeling methods. Additionally, it addresses the calibration and validation of computational models, analysis of dynamic response and failure characteristics, and evaluates retrofitting strategies to mitigate seismic risks. The research aligns with international preservation conventions and aims to contribute to the effective seismic risk mitigation strategies for unreinforced masonry heritage buildings.
