rubble retaining wall quantity calculation

A rubble masonry retaining wall is a type of construction that employs unshaped, natural stones of varying sizes and shapes to create a wall. This imparts a rugged and irregular appearance to the structure. These stones are bound together using mortar, which fills the gaps between them. Throughout history, rubble masonry walls have been a …

shear force and bending moment of point load

Shear force and bending moment are two important concepts in structural engineering and mechanics. Shear force, in simple terms, is a pushing or pulling force that acts parallel to the surface of an object. Bending moment denotes the internal moment within a structure that initiates a bend in a beam. The calculation involves multiplying the …
