The　Shear　capacities　of　fourteen　coupling　beams　are　analyzed　in　this　research　by　the　finite　element　numerical　simulation　method.　The　coupling　beams　are　designed　with　small　span-to-depth　ratios　and　arranged　high　strength　steel.　The　results　show　that　the　shear　capacities　of　coupling　beams　accord　with　the　compression　strut　model.　The　shear　capacities　improve　obviously　through　enhancing　the　diagonal　steel　bars,　but　they　do　not　show　significant　influence　through　changing　the　strength　of　transverse　and　longitudinal　bars.　Comparing　the　results　calculated　by　the　formulas　shown　in　the　Code　for　Design　of　Concrete　Structures　(GB50010-2010),　the　results　calculated　by　the　finite　element　method　show　the　gap,　and　it　will　be　the　key　issue　for　further　study.
