ƒ^ƒCƒgƒ‹�i‰p�j�F Pseudo- dynamic Tests on Steel Moment Resisting Frames and Non-linear Dynamic Analysis based on Simplified Plastic Failure Surface
�´˜^�i‰p�j�F To simplify the non-linear dynamic design procedure on steel moment-resisting frames to seismic actions, a new design-friendly reduced analysis is proposed. Global safety domain against plastic collapse of an elastic-plastic frame becomes a convex polyhedron, and its whole frame is approximated also by a hyper-ellipsoidal yield surface from a few reference points on the surface. Its validity is checked by comparison with the results of pseudo-dynamic tests of 2-story steel frame.
