The difference between buildings and structures

A building generally refers to a house or facility used by people for production, living, or other activities. For example, industrial buildings, civil buildings, agricultural buildings, and garden buildings, etc. Structures generally refer to places where people do not carry out production and daily activities directly inside. Such as water towers, chimneys, piers, dams, reservoirs, etc. In a broad sense, buildings refer to everything that is constructed by humans, including both houses and structures. In a narrow sense, buildings refer to houses and do not include structures. A house refers to a space with a foundation, walls, a roof, doors, and windows, that can protect people from wind and rain and serve as a place for living, working, studying, entertaining, storing items, or engaging in other activities. Structures refer to buildings other than houses, in which people generally do not carry out production or living activities directly, such as chimneys, water towers, bridges, dams, etc.

In a general sense, the literal meaning can be understood to some extent, but as for certain details – such as the steel structural platforms used to support equipment in workshops and those used for operations – do they qualify as buildings or structures?

Are structures those with roofs, and are those without roofs considered constructions? ? ?

The Chinese language is profound and complex; how about using a different word to express it? lol
