【Abstract】 In this paper the method of energy is adopted to analyse the inherent frequencies and relative vibrant models of shear blocks dowelled open web sandwich plates. The process of analysis and the solution of this method can be directly used to calculate the inherent frequencies of grid structures with intersection beams and RC open web grid structure.更多还原
