INSTRUCTOR: DR. GÜNEY ÖZCEBE



COURSE OUTLINE



CHAPTER 1: MATERIAL BEHAVIOR
(2 weeks)


In this chapter the stress
-
strain relationship for concrete and steel under monotonic, repeate
d and reversed cyclic
loading will be discussed and some mathematical modeling will be introduced. Moreover the behavior of
concrete under multi axial state of stress will be studied and mechanics of confinement shall be investigated.
Currently available c
onfinement models will be reviewed and formulation currently commonly used models will
be given.



CHAPTER 2: SECTION BEHAVIOR
(1 week)

Reevaluation of basic assumptions in the
Ultimate Strength Theory

will be made. Critical comparison of ACI,
European and

TS500 approaches will be given. Moment
-
curvature relationship for pure and combined bending
will be reviewed.



CHAPTER 3: MEMBER BEHAVIOR
(2 weeks)

A comprehensive review of
Plastic Hinge Concept
will be made. Redistribution of internal forces among the
sections and the members will be studied.



CHAPTER 4: YIELD LINE THEORY FOR SLABS
(2 weeks)

The yield
-
line theory for two
-
way action of plates will be presented. The fundamental concepts of hinge
-
field
failure (yield
-
line) mechanisms in flexure will be in
troduced.


Failure mechanisms and moment capacities of
slabs of various shapes subjected to distributed or concentrated loads will be discussed.



CHAPTER 5: BOND AND ANCHORAGE
(1 week)

Discussion topics will be: Mechanics of Bond, Application of Bond in E
ngineering Problems, Bond Tests and
Development of Bond Provisions.



This lecture will be given by Assistant Prof. Dr. Erdem Canbay.



CHAPTER 6: CRACKING AND DEFORMATION OF R/C MEMBERS
(
2 weeks
)

What are the causes of cracks in R/C members? Classificatio
n of cracks and basic principles of damage
diagnosis will be introduced. Frame analysis for shrinkage considering cracking. Deflection calculations using
moment
-
curvature relationship will be reevaluated. Approximate methods for deflection calculation will

be
given.



CHAPTER 7: STRUCTURAL CONTROL
(1 week
, optional
)

The question of
“What is structural control?”
will be answered. Modern control concepts will be introduced.
Structural control approaches for earthquake protection including passive base isolati
on and hysteretic devices
will be introduced.



This lecture will be given by Prof. Dr.
-
Ing Uwe E. Dorka of the University of Kassel, Germany



CHAPTER 8: STRUT AND TIE MODELING
(1 week
, optional
)

Discussion topics include: The background of strut and tie
modeling, B and D regions, Struts, Ties, Nodes,
Analysis Procedure, Model Optimization and design examples



This lecture will be given by Associate Prof. Dr. Burcu Burak Canbolat



CHAPTER 9: SEISMIC BEHAVIOR OF R/C AND PRECAST MEMBERS AND STRUCTURES
(2
w
eeks)

Basic requirements of seismic resistant design will be introduced. The relationship among strength, ductility and
the drift limitations will be investigated. Ductility in reinforced concrete, why is it needed and how is it
achieved? Discussion of com
mon causes of damage in earthquakes will be made and importance of structural
and architectural system configuration, detailing, and supervision will be emphasized. Seismic design
recommendations will be discussed.

EVALUATION & GRADING

The maximum course mark is 100. Students will write just one term test weighing 2
0
% and one final exam
forming 3
0

percent of the course mark (thus, tota
l of the two exams constitutes 5
0 pe
rcent of the course mark).
Besid
es
, 5
0 percent of the course mark comes from
seven or
eight homework
assignments
.
You are obliged to
submit
your solution for each
homework
. Failing to do

so

will lead to an
incomplete
term grade. Those who
fall in this
cate
gory

will
not be allowed to take the final exam

and their final grade will be
“FF.”

All
students will write
one opinion report constituting 5 percent bonus mark.



IMPORTANT POINTS

5
0% of the course mark will come from solutions to periodically assigned ho
meworks.
Anyone

who submits
all assignments on time and are deemed “
satisfactory
” will receive
5
0% of the course mark. “Satisfactory”
means a
complete solution to an assignment, submitted as an engineering brief, neat and well presented
.
There will be limi
ted partial credits for the homework solutions. The mark will be 0,
5
or 10 for each work, i.e.
only those who meet the above requirement will receive 10. There will be no make
-
up for
homework
assignment
s
.

Late homework submissions are
conditionally accept
ed
. Those submitted within one week past the due date
will be panelized 40 percent. In case of further delay no credit will be accepted.

Each student is expected to write an opinion paper based on his/her choice of reference(s), which will be
distributed d
uring the term. The due date of the opinion paper is the date of the
Final Exam
.

Besides the students described in
the
paragraph above, students failing to attend the scheduled
term test can
take the make
-
up on the last day of the semester.
Please keep in
mind that the make
-
up exam will be open to
those students having a legitimate excuse (e.g. a prolonged illness). The proof of the legitimate excuse shall be
submitted in written form (e.g. a medical report). Verbal excuses will not be accepted.

As you have

written to
resit exam

there will be no make
-
up of the final exam. Those who cannot attend the final exam shall take the
resit exam. The date of the
resit exam

will be announced by the Registrar.

NCE

Minimum acceptable attendance ratio is 70 percen

and their


LECTURES

Schedule will be decided in the first meeting on 26 September 2012.





EXAMS

Exam dates will be announced later.
