Is there anyone can help me to explan why the acceleration time history at nodes on the structure is too high (40g) and look weird.
I am working on nonlinear analysis of three-dimensional Soil – Underground subway structure interaction under earthquake loading in LS-DYNA. The solid element is used for both soil (MAT_079) and concrete (MAT_084/085), and the beam element for rebar (MAT_003). *DAMPING_FREQUENCY_RANGE option is adopted for damping simulation. Contact interface between soil-structure is used AUTOMATIC SURFACE TO SURFACE. The the acceleration time history in soil domain is fine but only problem in structure.
