Abstract:A comparison between known methods of producing an artificial rain under laboratory conditions and natural rain has revealed considerable differences. It is a striking phenomenon that different methods have been developed in the individual countries to simulate a driving rain for the testing of various building elements, although under natural conditions all building elements are exposed to identical forms of driving rain. A new method was thus developed to produce artificial rain. With this method, drop size and drop velocity of rain are identical with those of natural driving rain. Moreover, the testing conditions of such tests have been formulated in such a manner that various outdoor building elements--particularly joints--were tested. On the basis of the results obtained in the rain tests, practical constructions were, inter alia, recommended concerning the design of open joints between concrete curtain walls. The recommended constructions that have been translated into practice have proved their value.
