STATICALLY DETERMINATE STRUCTURE

DENINATION

A statically determinate structure is one where there is only one distribution of internal forces and reactions which satisfies equilibrium.

In a statically determinate structure, internal forces and reactions can be determined by considering nothing more than equations of equilibrium.

In other words, If a structure can be solved by equations of statics alone, it is said to be statically determinate.

Reactions and internal forces can be determined solely from free-body diagrams and equations of equilibrium

Types of determinate structure

statically determinate structures of the following types:

(1) pinned and rigid-jointed frames; (2) stiffened shear webs ; (3) thin-walled beams and torque tube
