An interface algorithm for nonlinear reliability analysis of reinforced concrete structures using ADINA

Efficient mechanical models are available for the analysis of reinforced concrete structures considering nonlinear material properties and the bearing capacity of the system. To take the statistical properties of loads and resistances into consideration a reliability analysis is required. The present paper describes an algorithm to approximate the limit state function, which is the condition to evaluate the probabilty of failure. Furthermore, a statistical model and extensions of the ADINA concrete model for use within a reliabilty analysis are presented.
