The Building Team- consists of

those

responsible for

financing,

designing, and

constructing

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.

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.

What

Does

Structural

Engineers

Do?

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)

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.

What isStructural Drawing?

A type of

technical

drawing.

Provides the reader

with a view of the

structuralmembers of the

building & how they

will support and

transmit its load to

the ground.

Structural DrawingsStructural drawings include:

Foundation plans

Wall sections and framing details

Structural steel framing and details

Beam and column drawings and

Stages of structural drawing

1 •Develop a general layout

2 • Investigating the loads

3 • Stress analysis

4 • Selection of elements

5 •Drawing and detailing

Developing a General Layout

Stage 1

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.

It is better to hire an experienced

engineer that knows the knowledge of

structural building for the general layout.

Investigating the loads

Stage 2

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.

Specifications and codes are usually

part of the general information about

the loads on the structure being

investigated.

Example of Codes

General building codes and

Design codes

(Which the engineer must satisfy)

Stress AnalysisStage 3

is the determination of the effects

of loads on structures and their

elements.

When live loads are involved, it is

important to determine the maximum

possible stresses in each member

being considered.

Selection of Element

Stage 4

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.

A trial-and-error approach may be

used in the search for a proportioning

of elements that will be both

economical and adequate.

A sound knowledge of strength of

material and process of fabrication is

also essential.

Drawing & DetailingStage 5

This final stage includes the preparation of

• contract drawing,

• detailing,

• job specification,

• and final cost;

these information are necessary for construction to proceed.

In the end, a structural

drawing would

look like this!
