The Building Team- consists of
those
responsible for
financing,
designing, and
constructing
the facility to
be occupied by
the owner at
the end of the
project

Structural Engineering
is a field of specialty within the
realm of civil engineering
is the application of math and
science to the design of structures, in
such a way that the resulting product
will safely resist all loads imposed
upon it.
![Page 4: Itd project 1](https://reader033.vdocuments.net/reader033/viewer/2022060112/556dceffd8b42a78768b4bea/html5/thumbnails/4.jpg)
The concept of design to a
structural engineer
is simply a matter of determining
what is to be built,
and preparation of the
instructions necessary for building it.

Structural engineering involves the
analysis, design, construction and
maintenance of structures.
A structural engineer's role is to ensure
that any built structure is safe and will
work. (in other words, not fall
down/warp/sink)
![Page 7: Itd project 1](https://reader033.vdocuments.net/reader033/viewer/2022060112/556dceffd8b42a78768b4bea/html5/thumbnails/7.jpg)
An Architect is dealing with the form
and function of the building, and
while s/he will be able to come up with
ways of making the structural
engineer's recommendations fit into
the plans, s/he doesn't have the
engineering know-how to assess the
safety of the building.

Stages of structural drawing
1 •Develop a general layout
2 • Investigating the loads
3 • Stress analysis
4 • Selection of elements
5 •Drawing and detailing
![Page 18: Itd project 1](https://reader033.vdocuments.net/reader033/viewer/2022060112/556dceffd8b42a78768b4bea/html5/thumbnails/18.jpg)
Developing a General Layout
Stage 1
![Page 19: Itd project 1](https://reader033.vdocuments.net/reader033/viewer/2022060112/556dceffd8b42a78768b4bea/html5/thumbnails/19.jpg)
This stage involves the choice of
structural type, the selection of
material, and a tentative estimation of
cost based on a reasonable analysis of a
preliminary structural design.
![Page 20: Itd project 1](https://reader033.vdocuments.net/reader033/viewer/2022060112/556dceffd8b42a78768b4bea/html5/thumbnails/20.jpg)
It is better to hire an experienced
engineer that knows the knowledge of
structural building for the general layout.
![Page 21: Itd project 1](https://reader033.vdocuments.net/reader033/viewer/2022060112/556dceffd8b42a78768b4bea/html5/thumbnails/21.jpg)
Investigating the loads
Stage 2
![Page 22: Itd project 1](https://reader033.vdocuments.net/reader033/viewer/2022060112/556dceffd8b42a78768b4bea/html5/thumbnails/22.jpg)
Before a structural analysis can be
carried out, it is required for the
maximum capacity of a structure to
be recorded and how it should be
designed.
![Page 23: Itd project 1](https://reader033.vdocuments.net/reader033/viewer/2022060112/556dceffd8b42a78768b4bea/html5/thumbnails/23.jpg)
Specifications and codes are usually
part of the general information about
the loads on the structure being
investigated.
![Page 24: Itd project 1](https://reader033.vdocuments.net/reader033/viewer/2022060112/556dceffd8b42a78768b4bea/html5/thumbnails/24.jpg)
Example of Codes
General building codes and
Design codes
(Which the engineer must satisfy)
![Page 25: Itd project 1](https://reader033.vdocuments.net/reader033/viewer/2022060112/556dceffd8b42a78768b4bea/html5/thumbnails/25.jpg)
Stress AnalysisStage 3
![Page 26: Itd project 1](https://reader033.vdocuments.net/reader033/viewer/2022060112/556dceffd8b42a78768b4bea/html5/thumbnails/26.jpg)
is the determination of the effects
of loads on structures and their
elements.
![Page 27: Itd project 1](https://reader033.vdocuments.net/reader033/viewer/2022060112/556dceffd8b42a78768b4bea/html5/thumbnails/27.jpg)
When live loads are involved, it is
important to determine the maximum
possible stresses in each member
being considered.
![Page 28: Itd project 1](https://reader033.vdocuments.net/reader033/viewer/2022060112/556dceffd8b42a78768b4bea/html5/thumbnails/28.jpg)
![Page 29: Itd project 1](https://reader033.vdocuments.net/reader033/viewer/2022060112/556dceffd8b42a78768b4bea/html5/thumbnails/29.jpg)
![Page 30: Itd project 1](https://reader033.vdocuments.net/reader033/viewer/2022060112/556dceffd8b42a78768b4bea/html5/thumbnails/30.jpg)
Selection of Element
Stage 4
![Page 31: Itd project 1](https://reader033.vdocuments.net/reader033/viewer/2022060112/556dceffd8b42a78768b4bea/html5/thumbnails/31.jpg)
The selection of suitable sizes and
shapes of members and their
connections depends on the results
of the stress analysis together with the
design provisions of the specifications
or codes.
![Page 32: Itd project 1](https://reader033.vdocuments.net/reader033/viewer/2022060112/556dceffd8b42a78768b4bea/html5/thumbnails/32.jpg)
A trial-and-error approach may be
used in the search for a proportioning
of elements that will be both
economical and adequate.
![Page 33: Itd project 1](https://reader033.vdocuments.net/reader033/viewer/2022060112/556dceffd8b42a78768b4bea/html5/thumbnails/33.jpg)
A sound knowledge of strength of
material and process of fabrication is
also essential.
![Page 34: Itd project 1](https://reader033.vdocuments.net/reader033/viewer/2022060112/556dceffd8b42a78768b4bea/html5/thumbnails/34.jpg)
Drawing & DetailingStage 5
![Page 35: Itd project 1](https://reader033.vdocuments.net/reader033/viewer/2022060112/556dceffd8b42a78768b4bea/html5/thumbnails/35.jpg)
This final stage includes the preparation of
• contract drawing,
• detailing,
• job specification,
• and final cost;
these information are necessary for construction to proceed.

drawing would
look like this!
