( Taiyuan University of Technology, Taiyuan 030024, China)Abstract: The horizontal coal bunker larger lateral stiffness change, we can see by calculating the stiffness of the floor is the structure of mutation in the weak layer, should pay attention to the role of seismic structure under the overall performance analysis. In this paper, finite element software MIDAS has adopted to the first 10,000 tons of domestic coal bunker structure of horizontal seismic performance of the response spectrum analysis. Selection of the structure, load value, structural analysis camed out a detailed introduction of the future must have a similar structure of the guiding role.
Keywords: horizontal coal bunker; lateral stiffness; seismic performance; response spectrum analysis
