ON IMPACT-LIKE FAILURE OF REINFORCED CONCRETE STRUCTURES BY HYOGO-KEN NANBU EARTHQUAKE (KOBE, 1995)
First, impact-like failure phenomena observed in Hyogo-ken Nanbu Earthquake (Kobe, 1995) are described. Second, stress wave transmission characteristics within a multi-layered ground excited by vertical ground motions are discussed through one-dimensional stress wave propagation analyses. Third, a stress amplification phenomenon in the cross section of column in a bridge R/C pier under a pulse-like vertical stress induced at the bottom face of footing slab is examined by 3D finite element method (FEM) analyses. Last, 3D FEM analyses for a bridge pier model supported by multi-layered ground model are carried out, and it is made clear that high frequency characteristics of vertical ground motions during the earthquake gave the most significant effect on an impact-like failure of R/C column due to large axial tensile and compressive forces.
