Abstract:
In proportioning concrete mixtures with the aid of computers, due regard must be given to such parameters as rheological properties of the mix and intensity of vibration. Translation of given relations into mathematical formulas presented here makes it possible to use automatic computers to calculate parameters of the mix. Simple relations are summarized in flow chart and block diagrams, and the calculations necessary for checking and adjusting the mix are introduced. After a simplification of the theory, the derived relations call be applied in practical production of ready-mixed concrete and in batching plants of large construction firms which have computers available. The whole process of computation is demonstrated by practical examples.

Thin shell analysis formulated by finite elements is described as a general procedure well suited to computers. Analysis of the individual elements can conveniently be done by numerical integration and examples are described for barrels, domes, and shell walls. Confidence in these analyses are established by studying for all shells the maximum integration length and for domes the required ficticious crown opening. The superposition method of analysis is described for continuous folded plates and finally a brief discussion is given of extensions in the numerical integration of barrels to include the inelastic behavior of reinforced concrete thin shells, particularly above working loads.

Standardized highway bridges have been automatically and economically designed by electronic computer in France since 1962. Computation procedure, programming details, and present capabilities are outlined, and. time and cost data are presented. Examples cited include a continuous T-beam structure and a closed-box culvert.

A brief description of the use of digital computers in an integrated operation by a major steel company for the purpose of estimating, detailing, and shop order entry of reinforcing bars. Explains the various equipment used and shows how the entire network of shops, engineering departments and sales departments is tied together through the use of computers.

A method of obtaining automated optimum cost design and detailing of continuous reinforced concrete girders serving as components of large structures is discussed and illustrated. The method has been successfully tested in automated optimum cost design of practical "one-way" solid slab, beam and girder, high-rise reinforced concrete buildings.
