| Research Abstract |
In order to develop a structural adaptability in seismic design of a reinforced concrete building, experimental and numerical studies were carried out. In these studies, three-dimensional stress transfer in a beam-column joint was focused, and static cyclic loading tests of corner beam-column joints and numerical analysis of exterior joints with FEM were conducted. As results of the studies, important knowledge was found as follows: three directional arrangement of reinforcing bars and adopting of thin reinforcing bars were effective for the three-dimensional stress transfer such as torsional stress; damages at the joint could cause degradation of torsional stiffness around the column axis; etc. Based on the knowledge, recommendations in seismic design of reinforced concrete beam-column joints were pointed out.
