Transportation　system　(TS)　and　electric　power　system　(EPS)　play　crucial　roles　in　the　functioning　of　modern　societies.　Disruptions　to　these　systems　can　result　in　severe　consequences,　such　as　substantial　economic　losses　and　public　safety　concerns.　The　growing　interdependencies　of　infrastructures　have　increased　the　vulnerability　of　TS　and　EPS　to　extreme　events.　However,　previous　works　have　not　adequately　considered　the　bidirectional　interdependencies　of　TS　and　EPS　when　assessing　their　resilience　under　earthquake.　This　study　develops　a　novel　framework　for　evaluating　the　seismic　resilience　of　urban　transportation-electric　power　system.　In　such　framework,　functionality　dependencies,　resource-sharing　interdependencies　and　restoration　independencies　are　incorporated　to　represent　the　interaction　between　TS　and　EPS.　A　weighted　connectivity　efficiency-based　metric　is　introduced　to　quantify　network　performance,　considering　both　topological　and　flow　characteristics.　The　framework　also　addresses　uncertainties　related　to　seismic　damage　and　repair　duration.　A　demonstrative　study　is　conducted　on　a　TS-EPS　system　located　in　Minneapolis,　Minnesota.　The　results　reveal　the　importance　of　considering　the　uncertainty　factors　on　the　prediction　of　network　recovery　trajectories　and　resilience.　In　addition,　the　effects　of　various　enhancement　strategies　on　network　resilience　are　discussed.
