Research On People Satety Evacuation Of Performance-based Design For High-rise Student Apartment Fire

Along with the booming development of our country’s economy and the risingprosperity of the higher education career, the number of college students has surged. Atthe same time, all kinds of emergencies happen repeatedly on campus, especially fireaccidents takeing place in high-rise student apartment buildings, which seriously affectthe security of students’ lives and properties and the construction of universities’science and education, even bring about bad social negative influences. High-risestudent apartments are almost of the double loaded corridor types and their planegeometric sizes are very large, with rooms arranged intensively and large population oneach floor. Due to long evacuation distances and the reality of more people and lessplace under a fire case, most students living in high-rise apartments face congestionbefore emergency exits and cannot be quickly evacuated, leading to missing theoptimum evacuation opportunity. Wht’s more, the high layer also bring great challengesto safe evacuation. However, safe evacuation is a necessary means for guaranteeingpersonnel safety in case of an emergency. In order to reduce the injury to teachers andstudents that caused by fire cases happening in high-rise student apartments, to motivatemore students to escape from fire safely, to improve campuses’ security and stability,based on the performance-based idea, the paper conducts research on the problem ofpersonnel safe evacuation when fires happen in high-rise student apartments. Thestudies aim at providing reliable basises and professional help for formulatinguniversities’ emergency evacuation plans as well as relevant buildings’ evacuationstrategies, performance-based evacuation design and evacuation evaluation technology.The main contents to be studied in this thesis are centralized on the following aspects: 1.The thesis details the idea of performance-based fire protection design as well asraises the drawbacks of the traditonal fire prevetion code and performance-based fireprotection design’s purpose, technology stages and basic procedure, which lay atheoretical foundation for the paper’s expanding studies.2.The thesis introduces the idea of performance-based safe evacuation design and theassessment criteria of safe evacuation, analyses fire factors influencing safe evacuationas well as the psychological and behavioral characteristics of human beings in the fireaccident, and gives the computing methods for Available Safety Egress Time andRequired Safety Egress Time, which creates the conditions for established a evaluationpattern of performance-based safe evacuation design.3.Taking a high-rise student apartment building for example, the thesis sets up aevaluation pattern of performance-based safe evacuation design. After the establishmentof fire scenario and the enactment of design fire according to the actual situation, theavailable safety evacuation time is obtained by FDS software simulation and therequired safety egress time is calculated through the empirical prediction method andthe Japanese hand algorithm. Afterward, the paper compares these two time values, andthen undertakes judging and discussing to the problem of the safe evacuation ofhigh-rise student apartments.4.Under the rule of meeting the evacuation performance requirements, the thesismakes quantitative calculation applying the fuzzy comprehensive evaluation methodto correlative factors that weaken the evacuation capacity of the high-rise studentapartment’s evacuation system, and evaluates the overall evaluation founction of theapartment’s egress system, which ensures safe evacuation process smoothly from adeeper level and also provides references for performance-based safety evacuationdesign.
