Study of the dynamical properties of simply supported reinforced concrete beams subjected to multiple loading : the second report, case of three concentrated loads

The authors have undertaken the study of mechanism of shear failure of reinforced concrete beams. This paper contributes test data, analyses, and consideratons resulted from this investigation which included the testing of 16 specimens of simply supported beams, subjected to 3 concentrated varying loads. The objects of this examination are to find some points on which may be occured maximum value of strain, researches of the strain in terms of the equivalent shear span, to investigate the capabilities of judicatory standards by a/d of the failured boundary and by theoretical equation of the ultimate bending moment, concerning with steel bar, deformed steel bar under and over reinforced concrete beams. Results of this exploratory test with the above mentioned objects are described in useful data on dynamical property.
