Seismic Response Control Of Coal Preparation Plant With Bucking-Restrained Brace

The new construction and renovation of the main buildings of coal preparation plants were powered by a heavy medium cyclone coal preparation technology requirements to meet their technology, equipment and other functions, the main buildings of coal preparation plant is often also the characteristics of the plane and the vertical are not rules. How to simply and effectively become one of the seismic performance assessment problem such irregular structure of the seismic performance, energy dissipation and damping technology is mature for the seismic design of the structure of a new idea.Finite element analysis software SAP2000as the method is used to establish the calculation model of bucking-restrained brace in the slime separation technology by using heavy media cyclone of steel structure of coal preparation plant at seismic fortification intensity8, site â…¡ area, is used to conduct the finite element analysis of the structure, including modal analysis, response spectrum analysis and time history analysis, comparing period ratios, displacement ratios, the maximal story displacement and inter-story displacement and the displacement time-history curves. The conclusions are drawn that the bucking-restrained brace can effectively improve the irregularity of vertical stiffness for the structure, which can make its dynamic properties regular and reduce the seismic response under frequently occurred and seldomly occurred earthquake.
