Abstract A new method of robust damper design is presented for elastic-plastic multi-degree-of-freedom (MDOF) building
structures under multi-level ground motions (GMs). This method realizes a design that is effective for various
levels of GMs. The robustness of a design is measured by an incremental dynamic analysis (IDA) curve and an ideal
drift response curve (IDRC). The IDRC is a plot of the optimized maximum deformation under a constraint on the
total damper quantity vs. the design level of the GMs. The total damper quantity corresponds to the total cost of
the added dampers. First, a problem of generation of IDRCs is… More >
