When a reverse beam and regular beam are adopted as a beam in an outer frame construction, the stress exerted during an earthquake in the beam-column joint is complex. The performance of the beam-column joint can change when a PCa concrete shell is used as the column and the PCa concrete shell is extended to the panel zone of the beam-column joint. Therefore, loading tests of three-dimensional beam-column joints were carried out and structural characteristics were examined. The results confirmed that the Q-R curves show excellent energy absorption and ductility properties. The ACT equation evaluates the maximum strengths with good accuracy. If each reverse beam and regular beam's direction is examined separately, even under bidirectional loading, it is possible to design for shear stress in any direction on the safety side.
