Abstract
The state of a structure can be described in terms of the complete set of state variables at any given time in its lifetime [1,2,4,5,7]. If the state of the structure is independent of the loading history, the structure is referred to as load path-independent. For such a case, the state of the structure can be expressed in terms of the current values of the loads and common response statistics. In these cases, there exists a unique surface in the basic variable space which divides the space into two regions, representing safety and failure of the structure. This limit state can be written in the form g(x) = 0. As will be discussed, the concept of such a function is not valid for load path-dependent structures. Instead, the concept of survival and failure paths must be used, and incipient failure directions determined for critical points.
