7. CE 261 Theory of Structures - part d
This chapter delves into fundamental concepts of structural analysis and loads that engineers must evaluate in civil engineering. Key topics include different types of loads, material properties, and essential equations governing mechanical systems. Understanding these principles is vital for designing safe and effective structures.

What we have learnt
- Structural analysis is predicated on understanding various loading conditions.
- Different types of loads must be evaluated, such as dead, live, earthquake, and wind loads.
- Material properties significantly influence the behavior of structures under different forces.
Key Concepts
- -- Dead load
- The permanent static weight of a structure including its material and other fixtures.
- -- Live load
- Transient forces that can change over time, such as occupancy or furniture.
- -- Young's modulus
- A measure of the stiffness of a material, defining the relationship between stress and strain.
- -- Shear force
- A force that causes parts of a material to slide past each other in opposite directions.
- -- Moment
- A measure of the rotational effect of a force about a point or axis.
