Abstract

Structural mechanics, sometimes called ‘solid mechanics’ or ‘mechanics of materials’ is concerned with describing the behavior of structural members under loading, as occurs in all buildings and other structures due to the effects of gravity and other forces (e.g. wind, earthquake, etc.). A detailed understanding of structural mechanics is essential for anyone seeking to competently perform structural fire engineering analysis or design.
