Abstract: Imitating the thought and method of performance-based design widely used in the field of fire protection,the theory,method and design process based on risk analysis were proposed,aiming at insufficient enterprise building structures fire separation.Applying the theory,the performance-based safety design of a petroleum reserve was conducted as a case study.Design process included determining equipment,storage material and related personnel within the tank farm that did not meet the regulations requirements as the design scope,Identifying the main risk factors was fire and explosion,determining the function index of the performance-based design according to the results of the structural importance of the main risk factors analysis,adding additional performance-based safety design measures such as high automation,water curtain spraying facilities,calculating the risk of the performance-based safety designed system in quantity and concluding that the value of performance-based safety designed system risk was lower than the value of the risk under the regulations requirements and the performance-based safety design met the target.
