Minicomputer oriented data acquisition and data processing systems are effectively used in full-scale structural tests. Digital computer techniques have greatly augmented the existing analog test techniques. Computerized systems are used to monitor structural behavior during the test and perform numerous on-line data management tasks. The new generation of data acquistion systems are microprocessor controlled and offer direct interfaces with minicomputers. This paper presents an analysis of data acquisition systems, computer interfacing, characteristic of data transmission and other hardware requirements. A complete description of an in-house computer controlled system is provided. An example of the operation of the system on a recent full-scale test is presented to highlight the benffits of the system to the structural engineers.
