CIVE 141 Civil Engineering Materials
Fall, 2022
By Dr. Yachi Wanyan, Ph.D., P.E.
rom my point of view: Early involvement in
engineering projects during a studentàearly
years increases his / her interest, excitement,
and retention in engineering. (see following
slides for detailsi

Become familiar with standards where material properties may
be found;
Become familiar with testing methods used in measuring these
properties;
Be able to interpret test results related to aggregates, Portland
cement concrete and bituminous mixes;
Design Portland cement concrete and bituminous mixes;
Identify the causes of failure of the civil engineering materials
like steel, timber, Portland cement concrete and bituminous
mixes; and
Gain hands-on experience with laboratory reports preparation
and documenting tests and results.

oals:
1.
Develop your own mini AI tool to automate
material selection process:
iven info:
? Material elastic modulus E
? Yield strength, Y
? Specimen shape and dimentions
? Type and magnitude of load
? Material selection criteria
utput:
? Automated selection of material
2.
Develop a reasonably easy to use interface to collect
user input and provide output.

he Turing Test
Interrogator
ehavioral Test designed by
Alan Turing (1950)
f a machine is programmed
well enough to have a
conversation with an
interrogator and fools the
interrogator (cannot tell
whether itàa machine or a
human at the other end), this

”o pass the Turing Test, AI needs to possess the following
capabilities:
Natural language processing to enable it to communicate
successfully in English;
Knowledge representation to store what it knows or hears;
Automated reasoning to use the stored information to
answer questions and to draw new conclusions;
Machine learning to adapt to new circumstances and to
detect and extrapolate patterns;
Plus the following:
Computer vision to perceive objects,
Robotics to manipulate objects and move about.
eak AI (also known as narrow AI): Defines
non-sentient computer intelligence or AI that
is focused on one narrow task.
ivil Engineering Material Selection
oncerns ourselves more with the algorithms
and mechanisms that underline human
intelligent behavior in the field of design,
construction and maintenance of
infrastructure such as pavements.
Knowledge-Base Systems (KBS): stores and uses knowledge, as
compare to pure data to reason and solve complex problems.
xpert System esign, diagnose
uzzy Logic: deals with inaccurate or imprecise information that
cannot be effectively handled by probability theory.
volutionary Algorithms: use iterative processes that are inspired
by biological mechanisms of evolution to evolve a population of
solution to a desired end.
enetic Algorithms inding optimal/near optimal solutions.
rtificial Neural Networks (ANN): Prediction, modeling and
simulation problems in cases where the inputõtput data are
noisy; the relationships between inputõtput variables are
multivariate and highly nonlinear; and the relationship is poorly
understood.
