Reliability Evaluation of Dynamic Systems Excited in Time Domain
Description
Reliability Evaluation of Dynamic Systems Excited in Time Domain is a multi-disciplinary guide that enables readers to solve problems they could not solve in the past by presenting reliability analysis procedures for seismic, wave, and thermo-mechanical loadings, addressing both statically and dynamically applied loadings in time domain, and allowing practitioners to perform hundreds of finite element method (FEM) deterministic analyses to extract reliability information and solve complex problems faster than with other methods.
To aid in reader comprehension, chapters include detailed examples and worked solutions.
Written by award-winning thought leaders from academia and professional practice, Reliability Evaluation of Dynamic Systems Excited in Time Domain addresses the following sample topics:
Fundamentals of reliability assessment, covering set theory, modeling of uncertainty, risk-based engineering design concept, and evolution of reliability assessment methods
Implicit performance or limit state functions, covering response surface method, experimental region, coded variables, and center point
Uncertainty quantification of dynamic loadings applied in time domain, covering earthquake time history selection methodology and validation of the broadband platform
Reliability assessment techniques for dynamic excitations applied in time domain, covering a novel reliability estimation technique and integration of finite element method
With comprehensive coverage of the subject and a focus on making the information accessible to all readers, Reliability Evaluation of Dynamic Systems Excited in Time Domain is perfect to use as a supplementary guide for upper-level undergraduate and graduate level courses on reliability and risk-based design.
