| 内容記述 | We have been developing a theoretical method of simulating deterministically the spatial variability of near field ground motions for the purpose of aseismic design and analysis of structures. This paper presents the characteristics of the temporal and spatial variability of near field ground motions, and the characteristics of the 3D nonlinear response of as steel truss bridge. The near field ground motions with large permanent movements due to a fault are simulated using the stiffness matrix method.The effects of the sedimentary layer and the depth of the upper edge of the fault upon the ground motions, and upon the nature of inelastic response of the steel truss bridge are examined. It is found that the seismic wave motions near a fault are quite complex and thiclmess of the sedimentary layer and spatial position strongly affects on the response behaviors of the steel truss bridge near the fault. | |||||
