A small sliding model and the contact pairs in large-scale finite element software ABAQUS are used to simulate the friction between pile and soil, and a good fitting curve of pile foundation bearing capacity is obtained. The application of ABAQUS in seismic analysis ofconnected structures The connected structure refers to the kind of building which is composed of two or more towers connected by the connecting body. Following the generation of the FE model, the FE mesh is controlled using Model Change in Abaqus to activate the weld elements for each bead at a time corresponding to weld deposition. The output in this example is a sequence of tuples containing the frame time and the displacement value. WARNING: There is no predefined system of units within Abaqus, so the user is responsible for ensuring that the. analysis, and that the elastic floor be used when calculated for the floor of connecting body. of increments = 150 • Time control *STATIC 0. The time-step is adjusted depending on the behavior of the Newton iteration and the accuracy of the time integration. The time history solution requires the use of the structure's mass matrix.
