Research Abstract

The objectives of the research are (a) to investigate the cause of structural damage in buildings, elevated highway and bridges, railway overpasses, considering the characteristics of strong ground motion during the hyogo-Ken Nanbu Earthquake, (b) to study the cause of heavy damage in underground structures such as the subway in Kobe City and (c) to develop new advanced civil infra-facilities using response control devices and to establish a new design for earthquake resistant structures of important roles.
The final research results includes ; 1. prediction of inelastic seismic response and damage of thin-walled steel bridge piers, 2. new mathematical model for predicting member force-deflection relation considering constitutive model developed for confined concrete as well as simple shear design equations, 3. effect of temperature and strain rate on fracture toughness of structural steel, 4. advanced unseating prevention of bridge by shock absorbing device made of rubber, and development of model predicting mechanical properties of rubber laminated bearing for base isolation system, 5. effect of vertical vibration of floor slab by vertical excitation on non-linear structural response of R/C frame structure, and 6. development of dynamic nonlinear FEM program dealing with R/C structures with multi-directional cracks applicable to under ground structure.
