Abstract:
Three knee connections were statically loaded and two were dynamically loaded as part of a preliminary study of the hinging characteristics of beam sections adjacent to beam-column intersections. In all knee connections, the mechanical and geometrical properties at the critical section were the same. The results were compared to those obtained in tests on similarly reinforced, centrally loaded beams. The knee connections failed when the concrete failed in bearing at the location of the corner bend in the tension reinforcement. The comparison of the knee connection and beam test results indicated that the maximum resistance and hinge rotation at maximum resistance for the knee connections were both less than the corresponding values for similarly reinforced beams. The reductions were attributed to the inadequate anchorage of the tension reinforcement. Although the dynamic resistance was not as great as expected, the rotational capacity at maximum resistance in the dynamic tests appeared to be equivalent to that in the static tests. (Author)
