Stress calculation and safety assessment method for spherical tank on differential settlement ground

A stress calculation and safety assessment method for a spherical tank on differential settlement ground is provided. A plurality of steps in an ANSYS analysis process are programmed to be a parametric command flow through an ANSYS secondary development language APDL (ANSYS Parameter Design Language), programming is performed in VB6.0 (Visual Basic 6.0) according to a parametric APDL code of a model, followed by background packaging, the above process can be visualized by means of a user interface program of human-computer interaction of VB (Visual Basic), a user can only input a calculating parameter on a system interface, background ANSYS software can be invoked for analysis through a VB invoking interface program and postprocessing can be performed through a VB postprocessing program, and a calculation result can be fed back to the user. According to the stress calculation and safety assessment method for a spherical tank on differential settlement ground provided by the invention, a complex ANSYS analysis process is visualized, stress calculation and simulation can be performed on a spherical tank on non-standard settlement ground, and the operation is simple.
