| Abstract: | The knee-brace-frames (KBF) is a new kind of energy dissipation bracing frames,its elastic-plastic analysis model has been discussed in the paper.First of all,Restoring force model of KBF is established.Secondly,analyzing model of knee-brace and computational method of equivalent damping and stiffness of knee-brace are established.Thirdly,elastic-plastic analysis method of KBF is presented.Finally,an example is presented to verify the method in the paper. |
