Analysis Of The Seismic Behavior Of The Cellular Framework Structure

In recent years, with high-strength lightweight, plasticity and toughness, good materials and more close to homogeneous isotropic, installation simple, sealing and make heat, green environmental protection steel structure get advantages of rapid development in the construction market. Well-known self-reverence is a important index of structure seismic performance, in guarantee strength conditions reduce self-weight can greatly improve the Anti-seismic capability. Cellular framework is a kind of structure which meet the strength and reduce self-reverence As far as possible. In practical engineering using cellular structures get through pipeline easily and using Honeycomb beam can ensure headroom condition, reduce the tall of building. In high-rise buildings would be more beneficial.Steel structure has good dynamic performance,and honeycomb framework use the mean of dislocation cutting and welding or holing to further reduce weight under the premise of satisfy the intensity, which reduces the structure on the earthquake effect reaction. But due to the influence of weakening of the hole, honeycomb structure is still disruption under the action of strong earthquake, mainly because people have not thoroughly analyze the influence of opening size and position to the hole structure under earthquake effect and related failure mechanism. Domestic and international related research mostly concentrated in the single honeycomb beams and columns such as individual component, and research in whole cellular framework is not so much.This article get structure characteristic of load-displacement, load-corner hysteresis curve, skeleton curves in the condition of unchanged vertical load, through pseudo-static experiment of Cellular frame structure model in the low cycle reciprocating load. Research anti-seismic performance of honeycomb framework and establish the restoring force model, through hysteretic performance, ductility and energy dissipation capacity and rigidity degeneration etc.of Structure under earthquake effect, and analysis stress mechanism and failure modes of honeycomb steel framework under earthquake effect. Comprehensive evaluation anti-seismic performance of cellular frame structure, lay the foundation For further research on cellular frame structure performance, and provide reference for engineering application.Compare the simulation results of ANSYS finite element analysis software with experimental results to verify the correctness of the simulation method, and use the finite element analysis software to simulation analysis a series of cellular framework with different opening form, different expansion ratio to explore the influence of two factors to Anti-Seismic performance of honeycomb framework. Compared and analysis the results, summarize aseismic performance of honeycomb frame comprehensively. Put forward some Suggestions to provide reference for engineering application.
