Study On Seismic Behavior Of Ceramicconcrete T-shaped Column

The construction industry accounted for the proportion of energy consumption has been closeto50%in our country, the energy-saving emission reduction work has been crunch time under thecurrent low carbon economy environment.As a lightweight aggregate concrete, because of its goodthermal insulation properties and the characteristic that it can make full use of industrial waste,ceramsite concrete plays a good role in promoting energy-saving emission reduction in theconstruction industry. As a kind of special-shaped column structure system, the T shape columnstructure system has gradually formed a mature system of structure in the development of nearly20years. Because it makes the building components inside spacious, neat, beautiful andeconomical, the T shape column structure system is widely applied to the engineering practice,there are good prospects for development.In view of current test and less of ceramsite concrete T shaped columns of variousperformance, need to be further investigated in the seismic performance of the direction of thecharacteristics, this paper designed7ceramsite concrete T shaped columns, the experimentalresearch on its seismic performance under low frequency cyclic loading.Through the research,revealing the failure mechanism under the load of ceramsite concrete T shaped columns undercyclic loading, rendering of ceramsite concrete T shaped columns under cyclic hysteresis curve,analysis of the factors affecting the axial compression ratio, stirrup ratio of ceramsite concrete Tshaped columns in seismic performance.The test indicates that, influence of axial compression ratio on the seismic performance ofceramsite concrete T shaped columns: General axial compression ratio increases, the bearingcapacity of members is higher, the ductility performance is poor, and the axial compression ratio ofceramsite concrete T shaped column member stiffness degradation influence is not obvious; withlittle effect on the hoop rate on load carrying capacity and stiffness degradation, effect on theductility is not very obvious.In addition, finite element analysis for the simulation of ceramsite concrete T shaped columncomponent based on the testing results is practiced in ANSYS, by changing the axial compressionratio, stirrup ratio and other factors, to study the influence of these factors of ceramsite concrete Tshaped columns in seismic performance, and finally compared with experimental results.Finally, the research work of this thesis is summarized, and suggestions for future researchdirection is put forward.
