Building construction today is a significant part of industrial culture, a manifestation of its diversity and complexity and a measure of its mastery of natural forces, which can produce a widely varied built environment to serve the diverse needs of society. This article first traces the history of building construction, then surveys its development at the present time. For treatment of the aesthetic considerations of building design,
he hunter-gatherers of the late Stone Age, who moved about a wide area in search of food, built the earliest temporary shelters that appear in the archaeological record. Excavations at a number of sites in Europe dated to before 12,000 BCE show circular rings of stones that are believed to have formed part of such shelters. They may have braced crude huts made of wooden poles or have weighted down the walls of tents made of animal skins, presumably supported by central poles.
A tent illustrates the basic elements of environmental control that are the concern of building construction. The tent creates a membrane to shed rain and snow; cold water on the human skin absorbs body heat. The membrane reduces wind speed as well; air over the human skin also promotes heat loss. It controls heat transfer by keeping out the hot rays of the sun and confining heated air in cold weather. It also blocks out light and provides visual privacy. The membrane must be supported against the forces of gravity and wind; a structure is necessary. Membranes of hides are strong in tension (stresses imposed by stretching forces), but poles must be added to take compression (stresses imposed by compacting forces). Indeed, much of the history of building construction is the search for more sophisticated solutions to the same basic problems that the tent was set out to solve. The tent has continued in use to the present. The Saudi Arabian goats’ hair tent, the Mongolian yurt with its collapsible wooden frame and felt coverings, and the American Indian tepee with its multiple pole supports and double membrane are more refined and elegant descendants of the crude shelters of the early hunter-gatherers.
