| Abstract: | The vibration characters of void slab and nonvoid slab were studied.The problem that viod rectangular thin slab with four simply supported edges on the upper part of Winkler foundation freely vibrates was transformed to the problem that nonviod rectangular thin slab with four simply supported edges was forced to vibrate and then the solution of the problem was obtained.The results of formula derivation and emulated analysis indicate that the vibration of void slab show character of local vibration,natural f... |
