Study Notes
Hooke's Law in Civil Engineering
- Describes the relationship between stress and strain in elastic materials, stating that strain is directly proportional to stress within the elastic limit.
- Fundamental for understanding material properties and structural behavior under load.
Non-Traditional Materials in Civil Engineering
- Advanced composites, such as fiber-reinforced polymers (FRP), are not classified as traditional materials compared to concrete, steel, or wood.
Rigid Body and Deformable Bodies
- Rigid bodies are idealized structures that do not deform under applied loads.
- Deformable bodies can undergo changes in shape or size when subjected to forces, crucial for analyzing material behavior in structures.
Free Body Diagrams (FBD)
- Used to visualize and analyze forces acting on a body or structure, isolating it from its surroundings for calculations of equilibrium.
- Essential for simplifying complex force interactions and solving static problems.
Construction Elements Outside Building Construction
- Civil Engineering encompasses infrastructure elements such as roads, bridges, and dams, which may not be classified under traditional building construction.
Mortar in Civil Engineering
- A binding agent made from a mixture of sand, water, and cement or lime, used for masonry and to fill joints between bricks or stones.
- Important for structural integrity and durability in construction.
Method for Deflection Calculation
- The Direct Integration Method is used to determine the deflection of statically determinate beams.
- This approach involves integrating the beam's bending moment equation.
Theory for Analyzing Compound Stresses
- Mohr's Circle is the graphical method used to analyze compound stresses and obtain principal stresses in materials under multiple load conditions.
Moment Distribution Method
- Primarily used to analyze continuous beams and frames, allowing for the calculation of moments at supports and joints under various loading conditions.
Type of Stress Causing Shaft Twisting
- Torsional stress is responsible for causing twisting of shafts, resulting from torsional forces or moments applied to a shaft.
Property of Concrete Related to Deformation
- Elasticity is the property of concrete allowing it to deform under load and return to its original shape once the load is removed.
Concept of Statically Determinate Structures
- A statically determinate structure has support and loading conditions that allow for equilibrium to be determined using static equilibrium equations alone, without needing additional methods or considerations.
