OpenSees Models for C-PSW/CF Archetype Structures

<p>This database includes OpenSees models to evaluate the static, cyclic, and time history response of composite plate shear wall --concrete-filled (C-PSW/CF) structures. C-PSW/CFs also called the SpeedCore systems are emerging as a viable alternative to reinforced concrete structures. To facilitate the adoption and widespread use of this structural system, a FEMA P695 study was conducted by the authors to recommend seismic design parameters. These parameters have now been adopted into ASCE7-22 with additional edits to AISC360 and AISC341 also stemming from this effort. The models included here were developed for this study but have applications beyond these uses to analyze other structures of interest with different geometries. Further information on the material models used, fiber layout, and other assumptions is included in the reference publications.</p>

<p>With this code, users can input wall geometries and provide a ground motion of interest and the program will output the time static and earthquake response of a 8-story structure. These outputs will be in the form of text files which the user can post-process to determine the force, displacement, stress, and strain response of various components. Please review the README file to understand the format these inputs should be in. All needed codes are included here except ground motions files which the user must provide. Some codes referenced herein are available directly from https://opensees.berkeley.edu/ and are included here as well for ease of use.</p>
