Abstract:
The construction of cast in place thin shell concrete structures involves many operations, all of which affect the final cost. Quantities of materials may have less of an influence of the cost of structure; whereas the methods and techniques of installing materials may be more significatn. Consideration of these cost factors should prompt one to design toward optimum solutions with construction as a prime factor, rather than stress values. With this in mind, we have attempted to evaluate certain shell types to find their optimum proportions.
