Study Of Comprehensive Evaluation System Of Safety And Cost In Building Fire Protection Design

Since the beginning of the fire with mankind,the fire has been accompanied by the development of human civilization,since ancient times,whether domestic or foreign,the fire is a very common disaster.Fire is not only a serious threat to economic development,but also directly endanger the social order.Especially in the contemporary,the level of urbanization is constantly improving,the city's building density is also increasing,if the sudden fire,its serious consequences are unimaginable.And people are fully aware of the dangers of fire,so the current continuous in the fire phenomenon and the development of the law in-depth study to effectively prevent and control the fire.In the study of this paper,we mainly study the fire type and its characteristics of public buildings.Based on the fuzzy multi-attribute group decision-making comprehensive evaluation method,the corresponding evaluation index system is constructed,and the fuzzy comprehensive evaluation model of building fire risk is established according to the system,and the safety and cost evaluation of building fire design are carried out.According to the Wanda public commercial building flow characteristics and fire requirements,put forward the criteria for the establishment of evaluation indicators.Based on the application safety and cost evaluation model of Lanzhou Wanda complex,the fire protection system of Lanzhou Wanda complex was evaluated from two aspects: construction design and follow-up status.Through the evaluation results,the existing problems in Wanda fire protection system were found,For the follow-up of the relevant optimization and secondary design to provide the necessary theoretical basis and practical support.This paper conducts an empirical study on the comprehensive evaluation of fire risk in Wanda of Lanzhou.Combined with the relevant theoretical knowledge and objective evaluation criteria,the Wanda fire system for the second design and optimization for the follow-up to improve Wanda fire safety and cost balance contribute.The research and analysis of this paper have verified the scientific and feasibility of the evaluation method,and the improvement suggestions of fire safety management and the optimization measures of building fire system are put forward according to the corresponding evaluation results.
