Reliability Analysis of Evacuation B Improved Response Surface Method
Due to lacking of explicit limit state equation in first order reliability method (FORM),solution is hard to obtain on building fire risk analysis; The direct Monte Carlo simulation will face huge computation.Therefore,a new analysis method based on improved response (IRS) is proposed,which constructed by uniform design (UD) and non-parametric regression (NR),and then,obtains the available safety egress time (ASET) and the required safety egress time (REST) probability distribution with Monte Carlo simulation.Through a practice of building fire risk analysis,the results show that UD picks up test inputs data together with alternative conditional expectation ACE regression for constructing response surface (RS) provide a small computation and good fitting effects method.
