A CASE STUDY ON THE RELIABILITY ANALYSIS OF DETERIORATING STRUCTURES

This paper presents a case study on the reliability analysis of deteriorating reinforced concrete structures where the deterioration of structural (material) resistance is caused by the corrosion of reinforcing steel under a specific environment. There are basically two types of problem in structural deterioration analysis. One problem is the need for models to simulate the behaviour of deteriorating structural material. The other problem is that when both the applied loads and resistance vary with time, the current methods to generate limit state functions for the structural system needs validating. To avoid this problem, an alternative formulation for time-dependent reliability is proposed, where the reliability analysis of a deteriorating structural system is based on the reliability of its structural components, which constitute a failure sequence for the structure. The advantage of the proposed approach is that it has effectively obviated the use of global limit state functions and that it is applicable to structures subject to various types of load and with different structural material properties. An example is given for illustration. (A)
