ST4005 Reliability Analysis of Structures Syllabus – Anna University PG Syllabus Regulation 2021

OBJECTIVE:

 To develop knowledge to solve structural analysis problems using reliability concepts.

UNIT I DATA ANALYSIS

Graphical representation Histogram, frequency polygon, Measures of central tendency- grouped and ungrouped data, measures of dispersion, measures of asymmetry. Curve fitting and Correlation: Fitting a straight line, curve of the form y = abx , and parabola, Coefficient of correlation

UNIT II PROBABILITY CONCEPTS

Random events-Sample space and events, Venn diagram and event space, Measures of probability interpretation, probability axioms, addition rule, multiplication rule, conditional probability, probability tree diagram, statistical independence, total probability theorem and Baye’s theorem

UNIT III RANDOM VARIABLES

Probability mass function, probability density function, Mathematical expectation, Chebyshev’s theorem. Probability distributions: Discrete distributions- Binomial and poison distributions, Continuous distributions, Normal, Log normal distributions

UNIT IV RELIABILITY ANALYSIS

Measures of reliability-factor of safety, safety margin, reliability index, performance function and limiting state. Reliability Methods-First Order Second Moment Method (FOSM), Point Estimate Method (PEM), and Advanced First Order Second Moment Method (Hasofer-Lind’s method).

UNIT V SYSTEM RELIABILITY

Influence of correlation coefficient, redundant and non-redundant systems series, parallel and combined systems, Uncertainty in reliability assessments- Confidence limits, Bayesian revision of reliability. Simulation Techniques: Monte Carlo simulation- Statistical experiments, sample size and accuracy, Generation of random numbers, random numbers with standard uniform distribution, continuous random variables, discrete random variables
