RM Bridge can perform SSI – Soil-Structure Interaction inside OpenBridge Designer with the addition of the structure underground infrastructure with foundations’ details and soil modeling springs. The soil-spring constants can be extracted from gINT reports or from a more complete PLAXIS modeling of the soil and the forces.
Moreover, when needed, PLAXIS can create the foundation model with detailed soil-structure interaction consideration through interface elements. It provides any structural forces in the piles along with soil reaction-displacement curves. In an equivalent linear indirect SSI analysis, the kinematic and inertial analysis of the Soil-Structure Interaction will then make sense because all the additional modeling and analysis effort could lead to significant savings in the structure design.
