Considering the unequal term of every column's u, the stability of frames with support is studied. The relationship of ultimate capacity and support stiffness is analyzed and discussed deeply. Moreover, the influence of asymmetry load is analyzed too. And then a series of conclusion are derived, guiding the practical design.
Keywords:  frame structure; support stiffness; ultimate capacity; effective length factor
