| Outline of Final Research Achievements |
The following three factors were observed in both shear-failure and flexural-yield-precedence types: 1) the actual bearing capacity of columns was overestimated because the bearing capacity of specimens with stubs, in which the arch mechanism is most effective and the plane retention assumption holds, is greater than that of specimens with beams at the ends; 2) the presence or absence of eccentric beams affects shear capacity; 3) the evolution of failure differs between the side where the beam is attached and that where the beam is not attached in the eccentric beams. The present study was limited to experimental investigations.
The present study was limited to an experimental investigation, and the FEM study of this experiment could not be conducted due to time constraints, but will be discussed and reported in the future.
