In this paper, strain based seismic verification method is proposed for hollow circular steel bridge piers subjected to the bi-directional earthquake motions. The elastoplastic analyses are conducted on finite element models with applying bi-directional circular cyclic loading. To catch the nonlinear cyclic behavior of the steel material, the in-house developed two-surface modified material constitutive law is employed. The strain results obtained from parametric study are used to derive failure strain formulas and seismic verification method.
