Note: is the cross-sectional area of compressive reinforcements; As is the cross-sectional area of tensile reinforcements; I0 is the inertia moment of components; l is the effective length of components. In this study, the sectional area of the steel bars was converted into that of the concrete material with the effective inertia moment during the calculation of the components’ inertia moment. The beam-to-column linear stiffness ratio is defined as the ratio of elastic linear stiffness, without considering the different calculation methods between the exterior and interior joints. Additionally, the beam-to-column linear stiffness ratio of the interior joints was reduced by half when comparing it with the theoretical limit values in the table above, based on the fact that the cross-sectional sizes and reinforcement configurations of beams framing the same joints were identical. |
