The Research Of Using Dissipation-energy In-filled Walls Improve The Energy Dissipation Of Frame Structure

In-filled wall frame has the advantages of flexible layout, entirety, well economic and adaptability, it has become a widely used structure form. More earthquakes have showed that most of the in-filled walls frame structures have good seismic behavior. Even so, in-filled walls still have some problems in earthquakes. We chuan earthquake in Si chuan province is an abrupt disaster.In this earthquake, some earthquake disaster phenomena of in-filled wall frame should be considered seriously. From the survey discovery, Building envelope structure and in-filled wall were destroyed obviously. The earthquake disaster mostly showed that between wall and frame there are lateral and vertical crack; cross diagonal crack of in-filled wall; because of lacking reliable connection walls dislocation collapse and so on. Even the destroy of nonstructural components can not influence the use of main structure. The collapse of envelope structure will cause casualties and enormous property loss. So the destroy of nonstructural components and the property loss are not secondary factor, we must seriously treat.Studying team have researched seismic of masonry structure and proposed a method that using cross diagonal steel strengthen masonry structure. On this basis, considering energy dissipation of in-filled wall in frame structure, this article introduces a mean of masonry structures reinforced by FRM, and research the effect of this method on energy dissipation. Taking the advantage of finite element analysis software Ansys10.0 and simulating to discuss about the feasibility of this method, on the basis of finite element analysis, studying team of author do experimental investigation. Test results showed that masonry structure reinforced by cement mortar can increase structural ductility and improve the seismic behavior of walls. This reinforcement method is feasible.Based on researching the reinforcement of masonry wall by using the principle of energy dissipation of metal, this article proposes another measure that using simple device to improve the dissipation of in-filled wall. Replace the material of middle pane using other good deformability, the numerical simulation is used to analysis this system and results show the device can improve the energy-dissipating capacity of in-filled wall. That can advance the ability of anti-collapse and dissipation of in-filled walls.
