Abstract:After the great Hanshin-Awaji Earthquake, we started the discussion about the combination of measures on earthquake. For example, one is to strengthen the design specification with earthquake. The other is how to evacuate after the occurrence of earthquake. In this study, we try to consider the combination of two required functions by the idea of multi state system (MSS). And we define the reliability of evacuation. Completed evacuation time is calculated by simulation. The reliability of evacuation is shown by the probability that completed evacuation time becomes shorter than required evacuation time. Then, we define the reliability estimation matrix using required evacuation time, number of sign, number of evacuation and so on. Key Words:Reliability of evacuation, Required function, Performance-based design, Multi state system, Performance matrix
