Mega Frame-support Structure System Energy Consumption Analysis Of The Seismic Performance

Earthquake's moving is a kind of sudden natural disaster, it bring person gigantic threat. The occurrence of earthquake will bring mankind injury that can not obliterate, therefore construct a structural anti- earthquake the research have been a hot topic of civil engineering realm. In recent years, as the development of economy, the growth of population, the space of people living is more and more urgent, leads to the city's construct continuously follow vertical to development, those high, big, more and more of new building emergence is in people's in front, this also causes many new of suited for extremely high structure system of layer of emergence. At the same time, the anti-of these structure systems shakes of function analysis and research also became more and more important.Currently, the eliminates of the technical research of ability to have become the civil engineering mega frame with energy-dissipating braces the research main current that. But mega frame with energy-dissipating braces can prop up structure system is a kind of new structure system, The adapt to ages to progress and combine to is combined with.Firstly the text introduced the characteristics and type of giant structure, on the foundation of structure power equation, building up to energy consume can reduce to shake structure sport differential equation and energy consumption to spread structure and adopt schedule analysis method calculation analysis; Choose of the large limited dollar of the calculation software Sap2000 carries on a mega frame with energy-dissipating braces the establishment that can prop up structure model, Through of the analyze of structure crest, layer moves, crest the layer acceleration and base shears dint and study it under the function that meet more and rare meet earthquake of reduce earthquake effect, and analyzed various layout and project bottom to consume can prop up reducing of structure earthquake effect.As research, mega frame with energy-dissipating braces can prop up the structure system just meets more and rare the bottom meeting an earthquake function reduce an earthquake to contain obvious effect, not only can let up a structural crest layer to move with acceleration, but also consumed the structural base to shear dint. Choose the different decoration project carries on contrast analysis, can get prop up decoration to be subjected to under the limiting circumstance at consuming, Energy consuming can better prop up decoration in the structure lower part of close together lord the structure layer reduce earthquake effect, structure of reducing and shaking the effect can also therewith set out of height from low arrive high gradually decrease; When eliminating can prop up close together in the structure lower part lord structure layer decoration, upper part lord structure layer of prop up of just degree big of the anti-vibration canned be good; Energy consuming can prop up consume ability of the machine follow sustaining of central part and the decoration reduce earthquake effect.
