Abstract:

The four essential problems facing a designer of concrete thin shells of revolution, more or less in order of importance, are construction, experiementation, analysis, and appearance.

Abstract:

Thin shells are unique among structural systems for the interest they inspire. Architects like the dramatic space-creating possibilites inherent in their forms, while engineers are impressed by the efficiency with which material is utilized. The fascination with shells is shared by critics.

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.

Abstract:

Virtually all common cast-in-place shell types have been built also as precast shells. Ample experience exists with such forms as precast long and short barrel shells, with elliptic and hyperbolic paraboloids, with spherical domes, with corrugated cylinders and, of course, with precast folded plates.

Abstract:

A multi-million dollar International Trade Center has recently been completed in New Orleans, Louisiana, a city which is second only to New York City in the U.S.A. in the volume of its international trade. The project is situated on a five acre plaza adjacent to the Mississippi River and consists of a 33 story Trade Mart tower providing 520,000 sq ft of office and commercial space, an International Convention and Exhibition Facility providing 250,000 sq ft of exhibition space, and parking below grade for 820 cars (see Fig. 5-1).
