Abstract:
This paper presents the results of an experimental investigation of the reinforced concrete (RC) dapped-end beams loaded with inclined forces, compared to identical ones loaded with vertical forces only. Such a load may occur in, for example, Gerber’s joints or in dapped-end beams supported on corbels, where the vertical gravitation force is additionally completed with horizontal forces caused by temperature differences, shrinking, or creeping. The problem of the state of stresses, cracking, and load capacity of dapped ends subjected to inclined forces, has not been experimentally sufficiently recognized. In the authors’ opinion, the results of the presented investigation establish conclusions that are useful in the theoretical verification of that type of structure.
