OpenSees Structural Model Database

This page included links to more than 30 OpenSees structural models created as part of this research. The following sets of files include not only the OpenSees structural models, but also include the Matlab pre- and post-processing files. We spent a great deal of time creating these pre- and post-processors, so I hope that you can find them useful and that it will make your research more efficient.

The files include pre- and post-processors to run the following types of analyses:

  • Static pushover analyses
  • Dynamic time history analyses for a set of ground motions with specified scale factors
  • Incremental Dynamic Analyses (IDA) from low levels of ground motion to collapse

The sets of structural designs contained on this page include:

  • Set of reinforced concrete (RC) special moment frame (SMF) buildings designed according to ASCE7-02 and ACI318-02, ranging in height from 1 to 20 stories.

Reinforced Concrete (RC) Special Moment Frame (SMF) Buildings Designed According to ASCE7-02 and ACI318-02

The reinforced concrete (RC) special moment frame (SMF) set of buildings comes from the following two references. These are two-dimensional three-bay frame models.

To run the OpenSees models, you will first need to set up your computer with a small set of folders on the C:/. The following are the instructions for setting up your computer and running the model, as well as links to the necessary files.

  • Instructions for dynamic time history analyses with scaled records. [link]
  • Instructions for static pushover and IDA analyses. [link]
  • Files to be placed on the C:/:
  • Earthquake ground motion files [link]. These files are for "ground motion set D" which is comprised on 78 records, and is an extended version of the ATC-63 Far-Field set. This ground motion set is explained here.
  • Examples of scaled ground motion sets, including illustrative examples of sets from the PEER Ground Motion Selection and Modification study on buildings (Haselton et al. 2009). [link].
  • The following folder will be were the runs take place. This folder is were you will place the structural models, and already contains the Matlab pre- and post-processors, the drivers to perform the analyses, and the OpenSees executable. This folder can be placed anywhere on your computer, but I suggest placing this on your C:/ because often long file names are developed in the output data. [link]

Now that your computer is set up for the models, you can now download the models and being doing analyses. The following table explains the available models and provides links to the model files. Note that the associated structural designs are also documented in the Structural Design Database and the predicted structural responses (displacement and acceleration responses, collapse capacities, etc.) are documented in the Structural Response Database.

Each of the models utilized a large number of the same files. Therefore, to reduce file sizes for download, you will also need to download these template model files and add them to the model folder. For example if you want to run model ID 1003, you would do the following:

  • Download the ID 1003 folder (from the link in the table below) and place it into the OpenSeesRuns\Models folder.
  • Download the template model files [here] and paste them into the ID 1003 model folder.

The following table outlines the 30 RC SMF OpenSees structural models (designs based on ASCE 7-02) created as part of this research. These are two-dimensional three-bay frame models. The links to these models are provided directly under this table. These models require the use of the model template and other files contained on the previous Structural Model Database page.

The table below in Excel format is available here.

Reinforced Concrete (RC) Special Moment Frame (SMF) Buildings Designed According to ASCE7-05 (Before Reinstatement of the Minimum Base Shear Requirement) and ACI318-02

To complement the ASCE7-02 designs, the following table also includes links to models which are based on ASCE7-05 structural designs (using the requirements before the minimum base shear requirement was reinstated into ASCE7-02). Do to the removal of the minimum base shear requirement, these buildings have substantially less lateral strength as compared to their ASCE7-02 counterparts (about 1/2 the strength for the 20-story buildings).

Note that the collapse capacities predicted by these models were used by the ASCE7 Seismic Subcommittee to inform their decision to reinstate the minimum base shear requirement (ASCE7-05 Supplement #2, 2007).

The table below in Excel format is available here.
