Abstract：

Experiment　study　on　a　dumbbell-shaped　CFST　arch　subjected　to　spatial　loads　under　non-directional　loads　was　carried　out.　The　lateral　load-displacement　curves　present　nonlinear　characteristics　in　the　initial　stage　of　lateral　loading,　which　is　caused　by　geometric　nonlinearity.　And　the　influence　of　initial　out-of-plane　imperfection　decreases　gradually　with　the　increase　of　lateral　loading.　The　preliminary　analysis　about　the　influence　of　non-directional　loads　on　a　dumbbell-shaped　section　CFST　arch　was　carried　out　on　the　basis　of　the　dual　nonlinearity　finite　element　model　verified　by　the　experimental　results.　The　analysis　results　show　that　the　positive　influence　of　non-directional　loads　on　the　spatial　mechanical　behavior　of　arch　structure　under　spatial　loads　becomes　more　obvious　with　the　increase　of　hanger　force.　©　2017,　Editorial　Office　of　Journal　of　Building　Structures.　All　right　reserved.
