Factorized high dimensional model representation for structural reliability analysis

B.N. Rao, Rajib Chowdhury

To develop a new computational tool for predicting failure probability of structural/mechanical systems subject to random loads, material properties, and geometry.

Numerical simulation of cracking in reinforced concrete members by an embedded model

Virgínia Maria Rosito d'Avila, Daiane de Sena Brisotto, Eduardo Bittencourt

The purpose of this paper is to describe the development of an embedded crack finite element (FE) model for reinforced concrete (RC) structures, including a bond‐slip methodology…

Reduced sampling for construction of quadratic response surface approximations using adaptive experimental design

Victor M. Pérez, John E. Renaud, Layne T. Watson

To reduce the computational complexity per step from O(n²) to O(n) for optimization based on quadratic surrogates, where n is the number of design variables.

Optimal randomized control policy of an unreliable server system with second optional service and startup

Dong‐Yuh Yang, Kuo‐Hsiung Wang, Jau‐Chuan Ke, Wen Lea Pearn

To study the optimization of a randomized control problem in an M/G/1 queue in which a removable and unreliable server may provide two phases of heterogeneous service to arriving…

Bootstrapping comparison on availability of parallel systems with non‐identical components

Jau‐Chuan Ke, Yunn‐Kuang Chu, Jia‐Huei Lee

In order to develop a feasible and efficient method to acquire the long‐run availability of a parallel system with distribution‐free up and down times, the purpose of this paper…
