Description

The most common cause of unstable models are failing member nonlinearities such as tension members.

The following model of a frame, whose columns are simply supported at the base point and have moment releases at the column head, serves as an example.

However, if it is loaded vertically, both tension members fail and the system becomes unstable, which causes a calculation error. You can avoid such an error by selecting the exceptional handling of failing members under ‘Calculate’ → ‘Calculation Parameters’ → ‘Global Calculation Parameters’.
