Abstract: The system reliability evaluation of ductile frame structures presents two difficulties. One is the identification of significant failure modes; the other is the computation of overall failure probabilities contributed ...

Abstract: First- and second-order reliability methods are generally considered to be among the most useful for computing structural reliability. In these methods, the uncertainties included in resistances and loads are generally ...

Abstract: In the second-order reliability method the principal curvatures, which are defined as the eigenvalues of rotational transformed Hessian matrix, are used to construct a paraboloid approximation of the limit state surface ...

Abstract: In the second-order reliability method, the Hessian matrix is used to construct a paraboloid approximation of the limit state surface and compute a second-order estimate of the failure probability. In this paper, a practical ...

Abstract: There are many areas of structural safety and structural dynamics in which it is often desirable to compute the first few statistical moments of a function of random variables. The usual approximation is by the Taylor ...

Abstract: In the second-order reliability method (SORM), the failure probability is generally estimated using a parabolic approximation of a performance function. In the present paper, the moment properties of a second-order ...

Abstract: In the earthquake resistance design of frame structures, the yielding of all the beams in flexure prior to possible yielding of columns is generally considered to be a preferable mode; this is defined as a beam-hinging ...
