Abstract The current code-conforming seismic lateral load patterns are implicitly derived based on the dynamic solutions of elastic structural systems, and there is a discrepancy with the nonlinear seismic response of deteriorating structural systems subjected to strong earthquakes, which makes the seismic damage cannot be predicted and controlled.In this paper, a new seismic lateral load pattern was proposed for deteriorating structural systems, based on the concept of uniform damage distribution.The peak-oriented modified I-K model was employed to construct the analytical model, and an optimization design procedure for uniform damage distribution was developed.The influence of main parameters on the new lateral load pattern was comprehensively investigated, including the convergence parameter, ground motion characteristic, target ductility, period, damping ratio, softening stiffness factor, material ductility ability and material cycle degradation rate.The quantified expression of the new lateral load distribution was proposed as a function of fundamental period, the target ductility and story relative height.The results show that the structures designed according to the proposed lateral force pattern achieved a uniform distribution of seismic damage, reduced the seismic response and enhanced the seismic response.

Key words： uniform damage lateral force distribution pattern seismic performance optimization design seismic design
