Based　on　the　geometrically　nonlinear　Kirchhoff　rod　theory,　the　snap-through　behaviors　of　an　asymmetrically　clamped　ribbon　under　midpoint　loadings　are　explored　through　a　numerical　approach.　The　pre　compressed　elastic　ribbon　would　experience　supercritical　pitchfork　bifurcation　and　transform　into　multiple　stable/unstable　patterns　when　subjected　to　lateral　end　translations.　With　its　midpoint　pushed　through　a　prescribed　path　and　beyond　a　threshold,　the　pre-deformed　ribbon　will　jump　to　other　inverted　equilibrium　configurations,　which　is　known　as　snap-through　buckling.　Instead　of　the　well-established　snap-through　behaviors　in　2D　bistable　beams,　we　observe　several　different　snap-through　processes　for　the　elastic　ribbons　in　a　3D　scenario.　Exploiting　the　efficiency　and　robustness　of　our　developed　discrete　model,　a　systematic　parameter　sweep　is　performed　to　quantify　the　snap-through　processes　of　elastic　ribbons　in　different　boundary　conditions　and　categories,　and　the　results　of　which　could　provide　a　fundamental　understanding　of　structural　mechanics　and　further　motivate　the　designs　and　applications　of　engineered　systems.　(c)　2021　Elsevier　Ltd.　All　rights　reserved.
