Abstract
This paper describes the seismic design and dynamic behavior in the transverse direction of shield tunnels with staggered-jointed rings. A series of shaking-table model tests and two forms of analytical analysis have been carried out. To model the structural properties of staggeredjointed rings, the decreasing in bending rigidity due to the transverse joints and the transmission of shearing force due to the circumferential joints is considered. In the tests, materials were chosen according to the similarity law. The two analysis methods were a dynamic two-dimensional Finite Element Method (FEM), and a static analysis based on a seismic deformation method using a beamspring model. The analytical values of sectional forces obtained from the seismic deformation method using the beam-spring model very closely matched the test values; thus, this analytical method can be proposed as applicable to the seismic design of shield tunnels in the transverse direction.
