Energy-saving Masonry structure is composed of combination ofautoclaved aerated concrete blocks,insulation mortar,concrete ring beamswith self-compacting lightweight aggregate and structural columns, it is anew masonry structure, which has light weight, easy energy-savinginsulation, processing advantages, but if you want to apply to this newreality of masonry, you should bearing a load-bearing walls in order toachieve energy-saving integration needs from both experimental andtheoretical analysis. In this paper, on the basis of pre-trial studies, using thefinite element method, carried out the following research on the seismicperfor mance of the structure:(1) Establish energy-saving composite structures masonry walls withfinite element analysis model, and simulation repeated load test oncompleted six weeks of low energy-piece co mbination of masonry wallsheet structure. Comparative results show that the finite element analysismethod presented in this paper can effectively simulate failure modes o fenergy-saving co mposite structures masonry wall piece, by the me chanicalproperties of me chanical properties, deformation performance,applicability.(2) Through the different structural columns with different aspect ratiospacing masonry walls for numerical analysis and calculation contrast. Theresults show that the actual structural column spacing of3m wall piece hasgood mechanical performance and deformation properties for engineeringapplications.(3) Statistics the test data of28energy-saving domestic portfoliomasonry wall patch, combined with95%guaranteed rate determined on themaximum story masonry composite structure energy-angle inelasticdisplacement limit of1/550.(4) The paper build a six-story masonry structure model and processdynamic elastic-plastic at least three seismic waves history analysis.Comprehensive displacement curves and damage the structure of thedistribution of the largest layer, energy-efficient co mbination of masonrystructures can meet the7degrees rare earthquake action, you can as aload-bearing structural system of the building in7degrees area, suitable forthe vast region. |
