To study the effects of tornado on long span transmission tower, a model of the tower is built and the features of the tornado are considered. Three different wind cases are discussed in dynamic analysis with finite element method. The analysis results show that dynamic response is more significant at 45° wind direction.

In consideration of the deficient study on dynamic response of reinforced concrete silos, especially group silos at home and abroad, taking the silos of one grain storage for instance, the dynamic response analysis of a single column-supported silo and that of group silos are carried out and contrasted through finite element method. Then the analysis results are contrasted with corresponding standards as well as academic studies.

In recent years, the cases that bridges under the action of debris flow been damaged have increased year by year. In this paper, the dynamic response of the double-column pier under the action of the debris flow are studied. Using the finite element method, considering the action of the upper structures dead load, the analysis of the changes about the displacement and stress of the pier bottom was conducted, as well as the deformation and stress changes in pile foundation.

The pressure fluctuation excited by the hydraulic pump can cause serious vibration in aero hydraulic pipeline system, which poses a serious threat to the safety of the aircraft. Therefore, an effective method for predicting the fluid pressure fluctuation and dynamic response of pipeline is strongly recommended. In this paper, a comprehensive model for predicting the dynamic response of pipeline, which includes the Poisson coupling, friction coupling, the vibration damping, Coriolis, and centrifugal forces is proposed. A numerical code is presented to solve the hydraulic pipeline equations. In this code, the hydraulic equations are solved by the method of characteristics and the dynamic equations of pipeline are solved by the finite element method combined with the Newmark algorithm. The numerical code is validated through the comparison of the dynamic response for a typical hydraulic pipeline with experiment. The obtained results indicate that the current combining method of characteristics and finite element method approach can predict the dynamic response of hydraulic pipeline with sufficient accuracy, which can serve as an efficient tool in the design and maintenance of aero hydraulic pipeline.
