Abstract:
A review of research activities directed to evaluating the onset of buckling of reinforced concrete folded plate stru-tures is presented. Guidelines and recommendations to the designer as to when buckling might be a problem and how to consider this in the design are also presented. The review includes a description of the development of methods of analysis and, for a limited application, specific formulas suitable for use with mini-computers. The validity of the analytical methods is discussed in view of a number of studies made on small, elastic models and tests on buckling of reinforced concrete plates. The results of the various studies, which were almost solely limited to prismatic structures, indicate local plate buckling, as opposed to lateral stability, is indeed a problem which should be considered for long-span structures. The present methods of analysis for buckling which consider the inelastic material response of concrete, are approximate but felt to be conservative.
