| Outline of Final Research Achievements |
To study the seismic response characteristics and collapse safety of steel structural frame at the time of maximum earthquake, the sophisticated analysis considering the strength degradation of each member is necessary. For the beam-to-column joint panel of steel structure, mechanical model for the one-way loading in the plane of structure have been proposed until now. However, the studies on the mechanical properties for two-way loading is one of the few. In this study, Stiffness and strength for the two-way loading is calculated by the FEM analysis. They are compared with the calculated value of the full plastic strength based on plastic analysis and of elastic stiffness, it was revealed to show a good correspondence. And it was revealed the failure and deformation performance of the RHS and circular steel tube panel by cyclic loading test. Based on these results, it was possible to set a simple analysis model to apply to the seismic response analysis.
