| Research Abstract |
As for reinfoced concrete beam- column knee joints, the minimum volume of panel concrete and effective arrangement of reinforcing bars which improves bond characteristic between bars and concrete in the panel and shear strength of the panels through empirical examination which is monotonic loading tests in the direction of closing direction of the joints. As a result, we found that large bending radius of main reinforcing bars which is 3-4 times as large as the ordinary standard hooks greatly improves bond characteristics and concequently significant improvement of shear strength results from that. those are also confirmed in monotonic loading test in the direction of openning or cyclic loading tests.
