Abstract:: To address the impact of different connection systems of the Ultra-High Performance Concrete(UHPC)cladding panels and the main structure on the seismic performance of the overall structure,two novel kinds of flexible and energy-dissipating connections between the UHPC cladding panels and the main structure were proposed in this study.Four single-story,single-span reinforced concrete(RC)frames were designed,including one RC frame with flexibly connected UHPC cladding panels,one RC frame with dissipative connected UHPC cladding panels,one RC frame with rigidly connected UHPC cladding panels,and a counterpart bare frame.Inelastic static analysis and nonlinear time-history analysis of the four structures were conducted using the finite element analysis software ABAQUS,and their mechanical properties and damage modes during earthquakes were compared and investigated.Results from the inelastic static analysis indicated that the ultimate damage modes were consistent for all four structures,and plastic hinges appeared at the ends of the beams and the bottom of the columns.In the rigid connection model,some of the connection bolts were damaged,and severe cracks appeared in the UHPC panels and the frame beam near the connections.In the flexible and energy-dissipating connection models,the connections and UHPC panels remained intact.The results from the nonlinear time-history analysis indicated that the displacement responses of the energy-dissipating connection model under the action of the three ground motions were reduced by 24.8%,32.9%,and 36.5%,respectively,compared to the flexible connection model,and the damage state of the energy-dissipating connection model hit by the strong earthquake was lighter,indicating a significant damage control effect.
