windPRESSURE - DAD Software for Rigid, Gable-Roofed Buildings

Sample Image
windPRESSURE - MATLAB-based Database-Assisted Design (DAD) for rigid, gable-roofed buildings This is the download page for windPRESSURE, a MATLAB-based Database-Assisted Design (DAD) software package for rigid, gable-roofed buildings.

The software, which incorporates a user-friendly graphical interface, uses pressure time series measured in the wind tunnel in conjunction with structural influence coefficients to compute peak values of the structural responses of interest (e.g., shear forces, bending moments, and displacements at various locations).

Pressure Databases The software reads pressure databases in standard HDF format, and sample HDF pressure databases are available for download below. The software incorporates an interpolation scheme to accommodate cases in which the dimensions of the building of interest do not match the dimensions of an available wind tunnel model.
Influence Coefficients Influence coefficients for the responses of interest are not computed by the windPRESSURE software, but they must be provided to the software in a spreadsheet-format building input file. Influence coefficients can be evaluated using standard structural analysis software, and sample building input files containing influence coefficients are available for download at the link below.
Directional Extreme Wind Speed Data The windPRESSURE software also allows directional extreme wind speed data to be used in conjunction with the measured pressures to compute peak responses corresponding to specified Mean Recurrence Intervals, and simulated hurricane wind speed data for this purpose is available for download below.
Downloading Software and Sample Datasets
Create a Folder for All Files It is recommended that users create a single folder named 'windPRESSURE' on their local hard drive in which to save all downloaded files and folders.
Requires Version 7 of MATLAB Software The windPRESSURE software was developed and tested in the Microsoft Windows environment using version 7 of MATLAB. It is believed that the MATLAB m-files can be ported to non-Windows (e.g., Linux/Unix) environments with minimal changes. However, the software will not run under version 6 of MATLAB since it makes use of features that were introduced in version 7.

If you do not have version 7 of MATLAB and you are running in the Windows 2000/XP environment, you can download and run the "stand-alone" file below. This contains a "compiled" version of the software.

File Formats In order to avoid individually downloading a large number of files, we have provided the files in archive format (i.e., only a single file has to be downloaded). Given that users may be running on different platforms and that some users may have firewalls that block the downloading of certain types of files, we have provided several alternatives for downloading.

Specifically, the following options are available:

  • The file may be provided as a self-extracting zip file. The advantages of this format are that the files are compressed (which speeds downloading) and that no software is required to unpack the files. The disadvantages of this format are that they only work for Windows platforms and some firewalls disallow the downloading of files with a "EXE" file extension.

  • The files are provided as non-self-extracting zip files. The advantage of this format is that it can be unpacked on Unix/Linux platforms (use the "unzip" command) and it can possibly be downloaded on Windows sites that disallow "EXE" files. The disadvantage is that Windows users will need software (typically the WinZip software, but it is possible that other archiving software can also handle this format) to unpack the files.

  • If for some reason you are unable to either download or unpack the zip files, we provide links to the individual files. The advantages of this approach are that it should work in cases where the other formats are not feasible and that it allows you to selectively download files (e.g., you may want to only download a small subset of the sample data or pressure files). The disadvantage is that it can be tedious and slow to download all the files individually.

Files Available for Download You can download the following files for the windPRESSURE software.
