<p> The objective for this thesis is to outline a Performance-Based Engineering (PBE) framework to address the multiple hazards of Earthquake (EQ) and subsequent Fire Following Earthquake (FFE). Currently, fire codes for the United States are largely empirical and prescriptive in nature. The reliance on prescriptive requirements makes quantifying sustained damage due to fire difficult. Additionally, the empirical standards have resulted from individual member or individual assembly furnace testing, which have been shown to differ greatly from full structural system behavior. The very nature of fire behavior (ignition, growth, suppression, and spread) is fundamentally difficult to quantify due to the inherent randomness present in each stage of fire development. The study of interactions between earthquake damage and fire behavior is also in its infancy with essentially no available empirical testing results. This thesis will present a literature review, a discussion, and critique of the state-of-the-art, and a summary of software currently being used to estimate loss due to EQ and FFE. A generalized PBE framework for EQ and subsequent FFE is presented along with a combined hazard probability to performance objective matrix and a table of variables necessary to fully implement the proposed framework. Future research requirements and summary are also provided with discussions of the difficulties inherent in adequately describing the multiple hazards of EQ and FFE.</p>

This thesis examines the use of aerial thermography data to discriminate loft (attic) insulation levels in residential housing, with ventilated pitched roofs, in the UK. Quantitative techniques from the fields of remote sensing, GIS, building physics and atmospheric science were used to develop a methodology and analyse survey data flown over Nottingham in 2001. The quantitative techniques were applied to real survey data using the most up to date atmospheric propagation models. A new model of the heat loss through the ceiling, loft and roof was developed for this study, based on the most recent methods. The limitations of these techniques were explored. A complete methodology, valid for any future study, was defined. It was found that, measuring roof surface temperature from the thermal image was complicated by roof material properties, the intervening atmosphere and the surrounding topography. Relating roof surface temperature to insulation thickness was further complicated by loft space ventilation and the outside surface heat balance. The additional data, needed to quantify the results, produced inaccuracies caused by measurement error. Analysis of the uncertainties, by simulation, indicated that loft insulation level could not be discriminated by aerial thermography. This was confirmed by comparing the results, calculated from the survey data, with the actual insulation level for a number of houses in test areas of the city.

Monitoring is a process of observing any changes on a monitored subject. Deformation monitoring is a process which consists of four stages: specification, design, implementation and analysis [Kennie et al., 1990], with the structure being monitored on a daily, hourly or continuous basis for any changes in position, size and shape. With the Global Positioning System (GPS), a 24-hour all weather monitoring system can be established. However, for kinematic GPS, un-mitigated troposphere and multipath remain as the main source of errors in the position residuals. These were investigated in detail using data from field trials conducted by the author which suite their particular purposes. The investigations were made using static and moving stations, and included stations at the same altitude, and stations with a high difference in altitude, and baseline lengths of less than ten kilometres. Using Adaptive Filtering (AF) technique, common signals in two time series can be extracted. By performing AF and interchanging position residuals time series as reference and desired (Forward and Backward) using consecutive days of data will show the multipath and this can be confirmed with a third day of data. While same day AF can be used to separate un-mitigated troposphere and movements from receiver noise. The position residuals considered in this thesis were processed with Leica Ski-Pro Version 3.0 software. These were validated and through comparisons made using a kinematic GPS processing software named KINPOS, developed by previous researchers at the IESSG, University of Nottingham and the use of Virtual Reference Station (VRS) data were also investigated by comparing with actual data. Through the field trials carried out on Snowdon, University campus, Humber Bridge and Forth Road Bridge, the novelty of this thesis is that it demonstrates that by better understanding the trends in unmitigated troposphere and multipath, the use of kinematic GPS for monitoring tall structures can be improved, making the results more suitable for engineers and building owners or managers to better assess building performance during extreme motions caused by traffic, earthquakes, strong winds, and other climatic conditions.

<p> Current building standards for protective design focus on a &ldquo;fortress&rdquo; approach that does not effectively protect against contemporary attack vectors such as active shooters. Furthermore, these standards provide little guidance to private building owners whose facilities are increasingly targeted by &ldquo;active shooters.&rdquo; This study combines the NetLogo agent-based modeling platform with the Autodesk Revit building design software to test key building geometry configurations for their impact on active shooter event casualties. The findings show that overall building geometry has an effect on active shooter casualties and that modifications to interior door alignment and the addition of direct exit doors can reduce the casualties in active shooter events. This research provides guidance to building designers who want to mitigate the risk of active shooter events with their building designs.</p><p>

This research firstly analyzes the prevailing practice of conducting sub project appraisals or feasibility studies under the scope of sustainability. Then the research debates on the existing capital intensive, people exclusive, quantitative methodology of conducting SARs and urges on introducing more people oriented right based approach of doing such type of study for donor funded projects in Bangladesh. From the study it was found that ADB launches a very detail feasibility study before launching RIIP 2 project where they looked at environment, social and economic aspect of the project components. The cut throat methodology of quantitative research was adopted with barely participation of the community. Whereas , if PRA was adopted as the tool for the feasibility it would have been less capital intensive and for inclusive from a right based perspective.
