To address the adverse interactions between infilled walls and frame columns,such as short-column damage under earthquakes,this paper proposes the use of high-performance foam concrete as an energy dissipation wall in the contact area between infill walls and frame columns.This approach aims to mitigate damage to the frame columns.Building on existing tests,the en-ergy dissipation wall-RC frame system was simulated.The model parameters and material consti-tutive relationships were carefully selected,and the element types of each member were identi-fied.A detailed finite element model of the high-performance foam concrete energy dissipation wall was then developed by defining the interactions between elements.The energy dissipation wall-RC frame was subjected to hysteretic loading in simulations to observe its earthquake re-sponse.Simulation results indicated that the energy dissipation effect of the wall is not significant at small story drift ratios.However,as the story drift ratio increases,the energy dissipation ca-pacity becomes more pronounced.Specifically,at a story drift ratio of 1/109,the energy con-sumption capacity of the wall increases by approximately 30.20％compared to an ordinary infilled wall.At a story drift ratio of 1/48,the capacity increases by approximately 21.54％.Compared with ordinary infilled walls,the maximum contact pressure between the frame column and the energy dissipation infilled wall is reduced by approximately 2/3 under the same displacement.These findings suggest that the proposed composite wall could provide valuable insights for the seismic design in areas with high seismic intensity.
