The Structual Seismic Performance And Damping Control Research Of Large Side Coal Thermal Power Plant

Power systems, as the lifeline of modern society, and we all aspects of life, playan important role in the national economy.Power systems should guarantee theseismic safety, the function of the lifeline, play the function of the lifeline, timelyprovide power supply and provide support for earthquake relief under the seismicaction. The main factory building with reinforced concrete frame structure, due to theproduction process requirement, its whole structure arrangement is complex, andirregular and poor seismic performance.The side of coal structure is new layout plan,can save covers an area of the main factory building, but the research of its seismicperformance is not enough. Taking a practical project as the research object, the sideof coal structure seismic performance are discussed in detail and the comprehensiveanalysis and research in this paper and the seismic performance is evaluated. At thesame time, in order to improve the seismic performance, this paper researches theviscous dampers suspension without shaft leakage protection technology, bearing typecoal scuttle shock absorption technology and use of upper structure of TMD dampingtechnology in the application of large side of coal thermal power plant.1. A typical side of coal seismic performance and characteristics of main factorybuilding structure were carried on the thorough analysis and research based onSAP2000and ABAQUS software platform, and its seismic performance under severeearthquake were evaluated.2. The bearing type coal scuttle damping technology is connected by isolationrubber mat coal and coal bucket beam, can provide three aspects damping effect,suchas isolation,energy dissipation and quality of FM.In a typical lateral structure of coalpower plant main building as an example, the supporting type coal scuttle theapplication of damping technology are studied, under severe earthquake action ofelastic-plastic time history analysis results show that this technology can improve theseismic performance of the structure.3. The large coal-fired power plants have standing local highlight layer at the topof the structure, earthquake damage is serious. In this paper will highlight layer as aquality piece, the TMD damping technology was applied in the power structure. In atypical lateral structure of coal power plant main building as an example, studied theapplication of damping technology, under severe earthquake action of elastic-plastic time history analysis results show that this technology can improve the seismicperformance of the structure.4. In this paper put forwards a no piston axis of viscous dampers, its basicprinciple is through the deformation of the corrugated tube oil cavity driven byviscous liquid by damping hole back and forth to dissipate energy. In theory there isno leakage hidden trouble, the damper performance test and finite element analysisshow that the damper structure scheme is feasible.5. The damper damping effect of a no piston axis of viscous dampers is analyzedbased on the three layer structure control Benchmark model, the results show that thedamping apparatus has a good damping effect, can be used in large thermal powerplant structural damping control.
