CAL CAD Packages for UG Civil Engg.Students

1. Software Packages for
Geotechnical Engineering Education

2. Effective communication is the essence of
education.
The process of learning can be enriched by
interactive software packages classified under
three heads
1. Computer Aided Learning (C.A.L.)
2. Computer Aided Design (C.A.D.)
3. Computer Aided Assessment (C.A.A.)

3. Essential features
a. Systematic organization of the teaching
material
b. Interactive and user friendly
c. Graphics and animation for better
retention
d. Scope for modification or improvement
e. Added utility as a teaching aid.

4. Computer Aided Learning or Designing
(CAL / CAD) packages
Developed by Dr.A.S.Nene,
Professor of Civil Engineering (Retired),
V.N.I.T. Nagpur

5. A new teaching aid for the teaching
staff and engineering students.
Developed during 1988 to 2000,
hence work better under DOS.
These softwares were a part of
undergraduate projects.

6. These packages were distributed to
various engineering institutes
in India and abroad.

8. QM+ (QUIZ and MAYA)
An interactive assessment program Helps in
preparing for viva -voce or any competitive
examination involving objective type questions.
special features.
Random selection of objective questions
Help menu
Time bound questions
Negative score for wrong answers
Can be used for any other subject.

9. MAYA
A tutor for ten basic experiments of soil
mechanics.
An electronic laboratory manual on any
other subject

10. 2. ISOTREC
Design of Isolated Trapezoidal,
Rectangular & circular Footings

11. Three independent programs for step-by-
step design of isolated trapezoidal,
rectangular & circular Footings.
Input data of loads, safe bearing capacity,
grade of concrete and steel.
Screen outputs shows design steps or final
design can be copied using printer.
Graphic display of the foundation designed
shows plan, section and reinforcement
details

12. EPYGRAM
(Earth Pressure bY Graphical Methods)
The package is for learning the
subject of earth pressures.

13. Three descriptive topics - introduction, earth
pressure theories and graphical methods with
text and figures.
The interactive topics- graphical methods by
Rehbann , Culmann and trial wedge method
Includes a new simplified graphical method
The interactive part - step by step solution for
active or passive earth pressures using
default or user’s data.

14. SOS
Stability Of Slopes
This package helps in learning
the topic of stability of slopes.

15. • Descriptive and interactive topics.
• Includes all conventional methods
such as
Swedish circle method
Friction circle method
Taylor’s charts
Bishop’s method
• Displays text, figures, charts and
references.

16. Shepi
Design of Sheet Piles

17. An interactive software package to teach the
design of sheet piles.
Theoretical background
Design of sheet piles under different ground
and backfill conditions.
Types of sheet piles covered
cantilever sheet piles,
anchored bulkheads
cofferdams
