- Structure ; A system of connected parts used to support a load
- Design of Structure :
1. Safety
2. Aesthetics
3. Serviceability ; How well it functions
Example of Serviceability
When using truss joints as a floor, there're many advantage of truss floor : Piping can go through of hole so that floor height will not be deducted, and It's light.
However, it vibrates by the lightness, like near a fitness room. As a result, this structure is great for safety as it is strong, but it fail in serviceability once it is applied in this situation.
H-Beam is heavier than truss system https://www.masters.com.au |

4. Environment
5. Economy
- Analysis of Structure
1. Strength ; how much it withstand the load
2. Rigidity ; how stiff it is (less deflect, more rigidity)
- Idealisation of Structure
1. Physical Model
- Members
- Connections
- Supports
- Loads
- Free-body Diagram
2. Mathematical Model
- Equilibrium Conditions
- Compatibility Conditions
- Constitutive Relationship

if the height is increased, I value will be tremendously increased as well.
which will reduce bending Stress Value then the beam can bear more load
