2 TYPES OF STABLE STRUCTURES

  1. Statically Determinate

  2. Statically Indeterminate


2
New cards

The equilibrium equations provide both the necessary and sufficient conditions for equilibrium

DETERMINACY

3
New cards

When all the forces in a structure can be determined strictly from these equations, the structure

STATICALLY DETERMINATE

4
New cards

Structures having more unknown forces than available equilibrium equations

STATICALLY INDETERMINATE

5
New cards

additional equations needed to solve for the unknown reaction

COMPATIBILITY EQUATIONS

6
New cards

fewer reactive forces than equations of equilibrium that must be satisfied.

PARTIAL CONSTRAINTS

7
New cards

support reactions are concurrent or when the reactive forces are all parallel

IMPROPER CONSTRAINTS

8
New cards

A structure (or truss) is externally unstable if all of its reactions are concurrent or parallel.

EXTERNAL STABILITY

9
New cards

A truss can often be checked by careful inspection of the arrangement of its members. If it can be determined that each joint is held fixed so that it cannot move in a “rigid body” sense with respect to the other joints, then the truss will be stable.
