This report deals with a fundamental study of inelastic seismic design methodology of tall structures with attention to anchor bolt yielding during earthquakes. To investigate the dynamic behavior of these structures, first, shaking table excitation tests were conducted for a tall slender model structure. Next, to interpret the experimental results, a simple mechanical model was proposed and the numerical response analyses were carried out. The following conclusions were obtained from these experiments and analyses. ( 1 ) When the response of the model structure dominantly increases under the resonant condition causing plastic deformation of anchor bolts, a greater amount of reduction of seismic design load for tall structures was observed in comparison with an elastic design. ( 2 ) As for the structural response time histories, satisfactory agreement between the experimental results and the numerical simulation results was obtained.
