Structural Analysis : How to check the stability of a structure

Proper investigation of structures stability is a vital aspect prior to start the analysis and design. Before starting the design of structures, it is important to verify whether the structure is stable or not.

In simple terms, stability signifies that structure doesn’t bear inflexible body motion and carries external forces and deforms.

To explain stability, two jargons are used - “Externally stable” and “Internally Stable” which are briefly explained in this video below. Structure becomes strong if and only it is stable from both externally and internally.

A skilled engineer can ensure the stability of structure through proper inspection as well as suggests necessary steps to transform an unstable structure to stable.
