Structure



** Structure **

​ A structure usually refers to any large, man-made object permanently fixed to Earth's surface or in its orbit, as a result of construction. These are divided into buildings and nonbuilding structures, and make up the infrastructure of a human society. There are also animal-built structures, such as anthills and beaver dams. Structures built by humans are broadly divided into categories because of their varying design approaches and standards:
 * Residential buildings
 * Commercial buildings and complexes
 * Industrial buildings, sites and installations
 * Civil constructions
 * Network infrastructure constructions
