Development length in beam-column joint
WebDate: 11/1/1978. Abstract: The behavior of interior beam-column joints unders seismic actions is examined in detail. The exisitance of two shear resisting mechanisms, one involving joint shear einforcement and the other a linear concrete strut, is postulated and the effects of reversed cyclic loading on these mechanisms, in both elastic and ... WebThe development length of strands in UHPC have been suggested as 40 or 42 times the strands diameter by different researchers [30,31]. Maya ... Therefore, for UHPC beam-column joints, the stirrups can be omitted, even the reinforcement ratio of the beam reached a relatively high level (1.21%) based on the test results.
