Mechanical and Structural Engineering



Open source/commercials

Application based (structure/mechanical/CFD)

e.g. Staad, SAP, Etabs, Lisa, Calculix etc.. etc..

•Deceptive pretty pictures and animations are generated•You will need the understanding of physical phenomenon to

interpret the result

•You will need fairly powerful computer and patience!

But Beware!!!



Analysis Design

Unsafe

We will focus in Structure’s Analysis and Design



Beams Columns

Slabs

Moment, Shear,torsion

Deflection, etc ..

Beam

Column Slab Footing

Section Dimensions,Reinforcement, etc..

Analysis

Design



Geometry Nodes

Beams/Plates

Materials (Concrete, Steel, Plastic etc)

Elasticity Poisons ratio

Density etc.

Section Properties Column section

Beam section Plate thickness (slab)

Units (use consistent unit system)

AutoCAD



1

• Create geometry

• Nodes/Beams/Plates

2• Define/Assign materials properties• Steel/Concrete

3

• Define/Assign section properties

• Cross section/ Slab thickness

4

• Define/Assign support (Boundary conditions)

• Support condition

5

• Define/Assign loads (and combinations)

• Point load/Udl/UVL

6

• Specify other parameters

• Releases, Offset, Design options, etc

7

• Specify analysis options• Assign analysis options

8• Run the model for analysis

9•

Verify your analysis (Important! But how?)Discuss

Two types of coordinates

Global (for whole structure)

Local (for component of structure)
