| Abstract: | The article introduces the general idea and common vibration combination of response spectrum and discusses things that need to be aware of when performing earth-quake resistance analysis on double arch bridge.Aimed at the construction practice of Wuli Bridge in Lingshan,Guangxi,the article proposes a detailed earthquake resistance strengthening plan.Also,by using finite structure calculation model,the article performs com-parison analysis on dynamic property and internal force before and after the strength... |
