| Abstract: | The modified formula for the boom of large complicated bucket wheel excavator has been put forward under earthquake,included the local dynamic effect.Considering the influence of local dynamic effect,the result of calculating is more accurate.When the dynamic response of a large complicated structure is analyzed,a more precise result and a more simplified calculation model will be got if the local dynamic effect is considered. |
