What is Structural Engineering
Structure as part of the Design Process
Basic Math
Strength/Stiffness/Stability
Today’s Takeaway Tips
Structural Engineering - Definition
A field of engineering dealing with analysis and design that supports or resists
loads
Design - As a concept
Lecture 1 - Structure: Strength/Stiffness/Stability 1
, Design as a 3-Step Process
1. Understanding the Precedents
2. Refine as Appropriate
3. Innovate when necessary
Structural Design - The Six (+) Step Process
1. (Architect) - System Selection and Figure out the building and layout
2. (Architect/MAYBE Engineer) - Early design work and feedback to the client,
using Rules of Thumb
3. (Engineer/MAYBE Architect) - Figuring out what ACTS on the building (loading)
4. (Engineer) - What do the loads do to every Member/Connection/System in the
building
5. (Engineer with input from Architect) - What members are Stable, Strong
enough and Stiff enough to meet all those loads?
6. (The Whole Team) - Rinse and Repeat
Structural Design - to an Architect
Lecture 1 - Structure: Strength/Stiffness/Stability 2
, You will need to know how to pick the “best” system, “best” layout and
approximate sizes (Rules of Thumb)
Tools:
Cool precedents
Sizing Guidelines (Rules of Thumb) - We will go over these for steel, wood and
concrete.
How to Use a Calculator
Exponents
Square, Square root, Cubed, Cubed root
Trig functions (SOH CAH TOA)
How to look things up on a chart/graph
How to interpolate
How to solve for X
How to rearrange an equation
How to put two (or more) equations together
Units
Math
Exponents - Base b and Exponent n
b^2, b^3, b^4, b^n
5^2 = 5 x 5 = 25
5^3 = 5 x 5 x 5 = 125
5^4 = 5 x 5 x 5 x 5 = 625
Roots - Opposite of Exponents (Don’t worry about Complex Numbers)
√x , ^3√x, ^n√x
