The incremental perturbation method is used to predict the critical behavior of space unit frame, and results are compared with those of previous studies on experimental measurement. Parameter studies on stiffness of joints elements and geometric initial imperfection angle are presented. The study shows that, 1. The connection between joint and member should be estimated as semi-rigid. 2. The flexural rigidity of joint elements have a great influence on post buckling behavior. 3. With imperfection angle less than 1.0°, the imperfection around the centroidal axis is more sensitive than the weak axis to the critical behavior. Continuous developments of computer environment make the method far more effective for the simulation of the critical behavior of space frames.
