Any attempt to develop a low-cost structural system must strive for minimal material and labor costs. The system proposed here reduces material costs through the use of an inherently efficient thin shell using economical cement with steel mesh reinforcement as the material. Labor costs are decreased by in-plant pre-forming of the shell sections and subsequent transportation to the erection site where the assembly operation is minimal. Another important criterion in the evaluation of low-cost housing systems is aesthetics. The inherent beauty of this shell system is combined with the simplicity of structural action to produce a very desirable housing unit. The smooth sweeping shell and arch shapes provide a striking effect both inside and out. The purpose of this presentation is to describe the feasibility and economic possibilities of this type of structural system.
