## Study Notes

### Structural Analysis

Structural analysis is a crucial aspect of civil engineering that deals with the calculation of the stress, strain, and stability of structures under various types of loads.

• Live loads: weight of people, vehicles, and other movable objects
• Wind loads: pressure exerted by wind
• Earthquake loads: forces caused by earthquakes
• Snow loads: weight of snow
• Thermal loads: changes in temperature affecting the structure
• Shrinkage loads: contraction of materials due to drying or curing

#### Types of Structural Analysis:

• Static Analysis:
• Deals with the behavior of structures under static loads
• Calculates the internal forces and stresses within the structure
• Dynamic Analysis:
• Deals with the behavior of structures under dynamic loads (e.g. wind, earthquakes)
• Calculates the response of the structure to time-varying loads

#### Methods of Structural Analysis:

• Classical Methods:
• Method of sections
• Method of joints
• Truss analysis
• Numerical Methods:
• Finite element method (FEM)
• Finite difference method (FDM)
• Boundary element method (BEM)

#### Structural Analysis Software:

• Commercial Software:
• Autodesk Robot Structural Analysis
• SAP2000
• ETABS
• ANSYS
• Open-Source Software:
• OpenSees
• PyFR

#### Applications of Structural Analysis:

• Design of Buildings:
• High-rise buildings
• Long-span bridges
• Industrial structures
• Design of Infrastructure:
• Airports and seaports
• Water treatment plants
• Assessment of Existing Structures:
• Condition assessment
• Rehabilitation and retrofitting
• Demolition and decommissioning
