Therefore, a nonlinear finite element model of the terminal was carried out using Ansys software. Subsequently, sensitivity analysis was performed by using a combination of Response Surface Method (RSM) and Monte Carlo Simulation (MCS). After that, the ratio of reinforcement required was calculated based on the results of the flexural moment values so the structural safety of the terminal can be finally verified. The obtained results show the importance of conducting probabilistic analysis to assess the structural safety of complex structures by understanding structural behavior when the uncertainty on material properties and loads is taken into account. © 2019 The Authors.

A part of Terminal 2E at Roissy- Charles de Gaulle Airport in Paris collapsed in 2004 and resulted in four casualties. The terminal is a large and complex structure consisting of three main parts: a main building, a boarding area and an isthmus connecting these two buildings. The boarding area, where the collapse occurred, has a length of 650 m and consists of 10 shells stiffened by curved steel girders (ties) braced to the two sides and held away from the shell by means of regular steel struts. str ct r a ilistic a al sis is se t assess t e safet f str ct res
