OPTIMUM SUBSURFACE AND UNDERGROUND SHELL STRUCTURES FOR BETTER HOUSING IN HOT-ARID LANDS. PART I: A CASE FOR SUBSURFACE AND UNDERGROUND HOUSING IN HOT-ARID LANDS. PART II: OPTIMIZATION OF SUBSURFACE AND UNDERGROUND SHELLS.
Abstract
This report consists of two distinct parts. A case was made for subsurface and underground housing in hot-arid lands in Part I. This includes discussions of environmental conditions, past developments of subsurface housing, new conceptual designs for dwellings, apartments, complexes of large and multiple buildings and transportation tunnels, etc. Part II of the report presents analytical optimization of subsurface cylindrical shells and completely underground shells, with a view to keep at a minimum the quantity of material used in the shells. The subsurface cylindrical shells are optimized by limit analysis, whereas the optimum shape and thickness distribution of the underground shells is determined by elastic analysis. Shapes of several shells have been determined as examples and design charts for general use have been prepared for all these shells. (Author)
