Abstract There are few studies on the dynamic-response mechanism of near-fault and far-field ground motions for large
underground structures, especially for the branch joint of a utility tunnel (UT) and its internal pipeline. Based on
the theory of a 3D viscous-spring artificial boundary, this paper deduced the equivalent nodal force when a P wave
and an SV wave were vertically incident at the same time and transformed the ground motion into an equivalent
nodal force using a self-developed MATLAB program, which was applied to an ABAQUS finite element model.
Based on near-fault and far-field ground motions… More >
