    Reliability-based structural optimization using neural networks and Monte Carlo simulation. 45th AIAA/ASME/ASCE/AHS/ASC Structures, Structural Dynamics & Materials Conference June Comparison of local and global approximation for reliability-based structural optimization A .

    The main aim of the present study is to propose an efficient methodology for tackling reliability-based seismic design optimization problems of steel moment-resisting frames incorporating the concepts of performance-based design.   This book provides engineers intuitive appreciation for probability theory, statistic methods, and reliability analysis methods, including Monte Carlo Sampling, Latin Hypercube Sampling, First and Second-order Reliability Methods, Stochastic Finite Element Method, and Stochastic Optimization.

      Focussing on structural reliability methods, reliability-based optimization, structural system reliability and risk analysis, lifetime performance and various applications in civil engineering. Invaluable to all concerned with structural system reliability and optimization, especially students, engineers, and workers in research and by: 9. An analytical and experimental study for assessing the potential of reliability-based structural optimization is proposed and described. In the study, competing designs obtained by deterministic and reliability-based optimization are compared. The experimental portion of the study is practical because the structure selected is a modular.
