INSPECT-SPSW: INelastic Seismic Performance Evaluation Computational Tool for Steel Plate Shear Wall Modeling in OpenSees

Modeling Steel Plate Shear Wall (SPSW) behavior can be computationally demanding. This is especially true when high-fidelity modeling carried out via shell or 3D solid elements. It has been shown that SPSW captured with adequate accuracy through the strip method nonlinear truss elements idealization. The widely accepted and reliable analysis platform, OpenSees, requires text-based input (.tcl) files created by a skilled programmer. Hence, Pre/Post-processing User Interface (UI) software package (INSPECT-SPSW) introduced herein. With basic input, INSPECT-SPSW allows user to create OpenSees file, run different analyses, retrieve visualize output. In addition, UI includes illustrated wrappers for several commands various material definitions, plasticity options, modal analysis, types. Validation verification were conducted against published results of experimental numerical cyclic loading specimens. user-friendly interface successfully accurate models capture behavior, including possible failure mechanisms. e.g., beam column plastic hinging, web plate yielding, etc. demonstrated performance intuitive UI, expected facilitate broad adoption Performance-Based Earthquake Design (PBED) SPSWs.
