HR_DAD - DAD Software for High-Rise Buildings

	Introduction
HR_DAD - MATLAB-based Database-Assisted Design (DAD) for flexible buildings	This is the download page for HR_DAD, a MATLAB-based Database-Assisted Design (DAD) software package for flexible buildings. HR_DAD calculates wind effects and estimates their mean recurrence intervals (MRIs) for structural members within the building. The wind effects currently only include the design interaction formulas. The software, which incorporates a user-friendly graphical interface, uses pressure time series measured in the wind tunnel in conjunction with the following information obtained separately from a structural model of the building: Modal period values Modal damping values Modal shapes Dynamic influence coefficients Structural member properties Static load reactions Information about these and other required inputs are described within the pages of the software or within the accompanying report (downloaded below).
Required Input as MATLAB Files	The HR_DAD software provides the ability to load required input information. All loaded information (e.g., items 3-6 above) must be stored in MATLAB format, i.e., saved previously as a data file within MATLAB. The directional extreme wind speed data (e.g., simulated hurricane wind speed data) required for MRI calculations is available for download below.
Example	The example of a 60-story building is available for downloading below. The pressure time series for the 60-story building, consisting of measurements in 10 degree increments around the building, is also available for download. These large files, however, are not required to view the results for this example.
	Downloading Software and Sample Datasets
Compiled Matlab Program	The HR_DAD software was recently (12/2008) rewritten by Seymour Spence while he was a guest researcher in BFRL. The new HR_DAD software runs as a "stand alone" MATLAB program. Stand alone MATLAB programs are compiled and do not require that you have MATLAB installed on your local platform.

Files Available for Download	You can download the following files for the HR_DAD software. Download and Installation Notes, Including Tap Numbering Scheme (PDF format and Word format) Note: Last Updated 10/17/2007 Stand-alone executable for Windows platforms (requires installation of MCRInstaller.exe from The Mathworks, Inc.) The "HR_DAD.exe" file is approximately 0.01MB while the MCRInstaller.exe file is approximately 87MB. Simulated Directional Hurricane Wind Speed Data (self-extracting zip file, non-self-extracting zip file, or individual ASCII files)
Files on CD	If you are unable to conveniently download the necessary files, you can request the files be sent on a CD (see the Contact Information below).
Contact Information	This software was developed by Dr. William Fritz and Dr. Rene Gabbai of the Building and Fire Research Laboratory at NIST. A separate download page is also available for DAD software for rigid, gable-roofed buildings, developed by Joseph A. Main.
