- Reactions are crucial for determining foundation loads.
- Static equilibrium requires that the summation of forces and moments equals zero.
- The presence of internal hinge connections adds equations for determining reactions.
Key Concepts
-
Term: Reactions
Definition: Forces that exist at the supports of structures, necessary for analyzing internal forces and stability.
-
Term: Static Equilibrium
Definition: A state where the sum of forces and moments acting on a structure is zero, indicating no motion.
-
Term: Statically Determinate
Definition: Structures whose reactions can be determined solely from equilibrium equations based on geometry and loading.
-
Term: Equations of Conditions
Definition: Relationships used to analyze internal hinges and connections in structures that help define reactions.
