Vertical Ground

In recent research of seismic engineering, the damage of bridge due to vertical motion aroused wide concern. Field evidence, experimental results and numerical simulation analysis suggested that vertical ground motion can significantly impact the seismic performance of reinforced concrete (RC) bridge. In this paper, firstly, a FEM model of a continuous rigid frame bridge in China was established . Then the bridge was analyzed using time-history analysis under strong earthquake . Internal force excluding and including vertical motion are compared.Then, the incremental dynamic analysis (IDA) and fiber model are used to calculated the vertical displacement of the node in the top of pier and the sectional curvature of pier. Computational results show that vertical ground motion can increase the internal force and displacement ,as well as reduce the ductility and moment capacity of piers. It is concluded that vertical motion can't be ignored in structure design.

An experimental and theoretical investigation into the seismic performance of steel encased reinforced concrete bridge piles is described. Six test units were designed, constructed and tested
under cyclic lateral displacement-controlled loading. The units had
an outside diameter of 360 mm and a steel casing thickness of 5 mm. Variables included the axial load level, inclusion or exclusion of internal reinforcing cages, and the influence of the casing continuity at he critical flexural sections. Sound seismic performance was observed in all of the models and good agreement between predicted and observed ultimate behaviour was obtained.
