It is critica. to ensure the functiona.ity of highwa. bridges a.ter ea.thqua.es to provide a.cess to importa.t fa.ilities. Since the 1971 Sa. Ferna.do ea.thqua.e, there ha. been a.better understa.ding of the seismic performa.ce of bridges. Nonetheless, there a.e no deta.led guidelines a.dressing the performa.ce of skewed highwa. bridges. Severa. pa.a.eters a.fect the response of skewed highwa. bridges under both service a.d seismic loa.s which ma.es their beha.ior complex. Therefore, there is a.need for more resea.ch to study the effect of skew a.gle a.d other rela.ed fa.tors on the performa.ce of highwa. bridges. This pa.er exa.ines the seismic performa.ce of a.three-spa. continuous concrete box girder bridge with skew a.gles from 0 to 60 degrees, a.a.ytica.ly. Finite element （FE） a.d simplified bea.-stick （BS） models of the bridge were developed using Sa.2000. Different types of a.a.ysis were considered on both models such a.： nonlinea. sta.ic pushover, a.d linea. a.d nonlinea. time history a.a.yses. a.compa.ison wa. conducted between FE a.d BS, different skew a.gles, a.utment support conditions, a.d time history a.d pushover a.a.ysis. It is shown tha. the BS model ha. the ca.a.ility to ca.ture the coupling due to skew a.d the significa.t modes for modera.e skew a.gles.
