I am conducting an earthquake-engineering study for a high-rise building and need the complete dynamic analysis performed in OpenSees (spelled “opensess” in the brief). The model must capture the building’s global and inter-story response under ground-motion records and ultimately provide displacement and drift results that I can slot straight into my larger performance-based design report. Scope of work • Build or refine the finite-element model of the building in OpenSees, including gravity load cases, material non-linearity where appropriate, and all required dynamic mass participation. • Select, scale, and apply representative earthquake records (I can supply them if you prefer) and run the full time-history analysis. • Extract, plot, and tabulate floor displacements, inter-story drifts, and any other intermediate data required to verify the results. Deliverables 1. All OpenSees input files (.tcl) ready to rerun. 2. A concise PDF report containing: – Story-by-story displacement and drift graphs, – Peak and residual drift tables, – A short commentary on model assumptions, damping, convergence, and verification checks. 3. A brief “read-me” noting how to reproduce the results on a standard OpenSees installation. Acceptance criteria • Drift results reproduce within 2 % when I rerun your files on my machine. • Plots are clearly labeled and dimensionally consistent. • Model assumptions and parameter choices are transparent and justifiable. If you are comfortable with OpenSees scripting, dynamic time-history procedures, and extracting drift demand for tall buildings, this job should be straightforward. I’m responsive and can supply architectural/structural drawings plus any code spectra you might need once we start.

Hi there, This is right in my wheelhouse. I’ve worked with OpenSees on nonlinear dynamic analysis for multi-story buildings, including full time-history runs, drift extraction, and clean, repeatable TCL setups. I’m comfortable building or refining FE models, defining mass and damping properly, and handling convergence issues so results are stable and rerunnable. I can run scaled ground motions, extract floor displacements and inter-story drifts, and present everything clearly in plots and tables that drop straight into a performance-based report. I always document assumptions (materials, damping, checks) so nothing feels like a black box. You’ll get clean OpenSees input files, a short PDF report, and a simple read-me so you can reproduce the results on your machine within the 2% tolerance. Happy to work from your records or select them myself.

Hello, hope you are doing well. I can perform the complete dynamic time-history analysis of your high-rise building in OpenSees, delivering reproducible displacement and inter-story drift results ready for direct inclusion in your performance-based design report. The scope will include finite-element modeling with gravity and dynamic load cases, nonlinear material behavior where required, ground-motion selection and scaling, and full post-processing of drift and displacement demands. I have 10 years of experience in structural and earthquake engineering analysis, including a recent high-rise seismic study where OpenSees was used to evaluate global response and story drift under multiple scaled ground motions. Will you be providing target damping ratios and code-based scaling criteria for the records, and should the model follow a lumped-mass shear building idealization or a detailed frame/wall element formulation? Thank you. Maksim
