The Study On Seismic Performance And Damage Of CS Plate Structure Based On Pushover Analysis And Test

With the world wide energy crisis, environmental protection and energy conservation has been growing concern, so building energy efficiency is an important energy saving measures. Develop the new building structure system of the light-weight, high-strength, energy conservation and environmental protection, resist earthquake, reducing costs, and has a certain construction production industrialization is imperative.CS plate structure system is developing on this background .Its advantages have: reduce the wall weight, improve the seismic capabilities, enhance the effect of thermal insulation and energy conservation, simplify construction method, etc. Based on the low-cycle and reverse loading test and the Pushover analysis of the two kinds of CS plate structure (that is structural columns and no structural columns CS plate type structure), this text makes the further research in the aspects of evaluation of seismic performance. The main contents have:1,To compare the two models test in the aspects of carrying capacity, energy dissipation capacity ,stiffness degradation and damage, etc. Research and analysis the seismic performance of the CS plate structure with the different node forms, and based on the different destruction reasons recommend the different strengthen measures.2,Use SAP2000 analysis software, establish finite element model, conduct modal analysis. And using quality participate factor, judging the modal properties of the two kinds of CS plate structure.3,Conduct the static nonlinear analysis (namely Pushover analysis), evaluate the seismic performance of the CS plate structure. And conduct under cyclic loads Pushover analysis, according to the definition of structural damage index, and judge the damage degree of the CS plate structure.Finally, get the following conclusion: The CS plate structural with structure column seismic performance is better than no structural columns, so in practice, preference should be given. Two kinds of CS plate structure can be used for seismic intensity of 7-degree earthquake zone. Structural damage index based on under cyclic loading Pushover analysis can be used for CS plate structure.
