EARTHQUAKE RESISTANT DESIGN OF UNBRACED FRAMES

A seismic design procedure which forces all significant inelastic behavior into the girders of moment resistant frames is presented. A prescribed response spectrum and modal analysis are used to determine the seismic design forces. The members of the frame are proportioned using ultimate strength concepts. Important design parameters are the expected girder ductility requirement and the rate of strain hardening. Ten story single bay frames are designed according to the proposed procedure and according to the standard allowable stress procedure. These frames are subjected to two strong earthquakes and the inelastic response is evaluated.
