G.7 Member and Element Release
STAAD.Pro allows releases for members and plate elements.
One or both ends of a member or element can be released in any combination of the six degrees of freedom. Members and elements are assumed to be rigidly framed into joints in accordance with the structural type specified. When this full rigidity is not applicable, individual force components at either end of the member can be set to zero with member release statements. By specifying release components, individual degrees of freedom are removed from the analysis. Release components are given in the local coordinate system for each member. Partial moment releases are also allowed.
