Abstract:
Computer analysis of compression tests of concrete provides a rapid evaluation of quality, uniformity, and testing discrepancies. The computer can be programmed to determine compliance with project specifications and to develop the information recommended by ACI 214-65. Reports serve as a record of concrete in place and as a means of establishing the adequacy of the concrete mix for continued or future use.

Digital computers are used for control of concrete quality during its manufacture and for analysis and interpretation of concrete test results. Statistical parameters normally used for quality control are defined and their use is explained with the help of job control charts. The three case histories presented show: (1) the use of computers in establishing the degree of reliance of the strength of accelerated-cured test cylinders; (2) the multiple correlation analyses of 1176 compressive strength test results and several independent variables; and (3) a computer method for the trial and error fitting of a hyperbolic curve to compressive strength test results.

An integrated system employing computer-based techniques for data processing and analysis and information storage and retrieval is described. This system serves for the evaluation of concrete quality, the selection of concrete to best match a structural design, and for the study of performance.

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.
