大型公共建筑风险评估框架研究

General Framework of Large-scale Public Building's Risk Assessment

大型公共建筑是开放复杂系统,其风险由可靠性风险、安全性风险和可持续发展性风险构成。大型公共建筑的风险评估、需要从系统的角度,针对3类风险的不同特性,采用定性与定量结合的方法,进行系统的风险评估。针对可靠性风险侧重系统的可靠程度评估,安全性风险侧重风险源和系统脆弱性评估,可持续发展性风险侧重关联风险事件评估。大型公共建筑风险状况由3类风险的评估结果共同确定。

Large-scale public building is an open complex system and its risk is made up of reliability risk,security risk and sustainable development risk.The method of large-scale public building＇s risk assessment is a quantitative and qualitative integrated systems assessment method,which is in the systems perspective and to the essence and unique characteristics of large-scale public building＇s risk.To reliability risk,we put particular emphasis on system reliability assessment.To security risk,we put particular emphasis on security risk source assessment and system vulnerability analysis.To sustainable development risk,we put particular emphasis on related risk event assessment.The final result of large-scale public building＇s risk assessment is comprehensive synthesis of such three risk assessment results.
