Abstract

DIRECTIONAL SIMULATION, among techniques for reliability analysis of engineering structures, is well known. In this context, DIRECTIONAL SIMULATION in LOAD SPACE, because of the advantages of lower dimension of working space, is of considerable interest. As expected due to structural RESISTANCE VARIABILITY, the location of the relevant limit state (s) along any simulated direction, is no longer constant and must be taken as a random variable. The accuracy of the results obtained using this type of simulation therefore depends on how well this random variable probabilistically is modeled in analysis. In order to describe probabilistic properties of this random variable, one simplified solusion is to use only the first two moments which implies the use of normal distribution. This paper intends first to verify how taking this distribution may affect the accuracy of the results (i.e. estimation of the probability of failure) and second, to propose alternative solution (s) in order to enhance the quality of the method in the cases where the above simplified method may lead to poor results. In the examples given in this paper, the quality and workability of the proposed solution (s) are compared with the simplified solution and finally some practical recommendations are given.
