STATICALLY DETERMINATE AND INDETERMINATE BEAMS || STRUCTURAL ANALYSIS || SIMPLE BEAM || FIXED BEAM

BEAM – statically determinate beam
A beam is generally supported on a HINGE AT ONE END AND A ROLLER BEARING AT THE OTHER END.
THE REACTIONS ARE DETERMINED BY USING STATIC EQUILIBRIUM EQUATIONS.

Such beam is a statically determinate structure
BEAM – statically indeterminate beam
If the ends of the beam are restrained/clamped/encastre/ fixed then the moments are included at the ends by these restraints and this moments make the structural element to be a statically indeterminate structure or a redundant structure.
These restraints make the slopes at the ends zero and hence in a fixed beam, the deflection and slopes are zero at the supports
