Window Glazing Analysis Response and Design (WINGARD)

Window Glazing Analysis Response and Design (WINGARD) was developed for GSA by Applied Research Associates (ARA).  The goal was to develop a simple but accurate analytical model of the response of windows to the effects of an explosion.  The program calculates and graphically displays the response of window systems subjected to blast loads. This software is available in three versions:

  • WINGARD LE 2.0 (Limited Edition)
  • WINGARD PE 5.5.1 (Professional Edition)
  • WINGARD MP 1.0 (Multi-Pane)

WINGARD PE accepts user input of window system properties and explosion characteristics, and calculates the performance of the window system. 

WINGARD LE is a program that analyzes the design and response of windows during an explosion using a subset of the capabilities of WINGARD PE.  The following summarizes the significant differences from WINGARD PE:

  • Provides default values for glass/membrane material properties.
  • Contains reduced lay-up types (simplified input options only at this time).
  • Has a simpler, more intuitive user interface.
  • Graphs fragment flight, blast loading, and dynamic reactions only.

WINGARD MP is an advanced program that is capable of analyzing multi-paned window systems. WINGARD MP utilizes the existing analysis models contained in WINGARD PE coupled with a Finite Element Analysis (FEA) code to model the combined response of the windows and the supporting framing, mullions, or muntins. The FEA code is based on FEAPpv, which was developed by Dr. Robert L. Taylor at the University of California at Berkley. WINGARD MP was developed by ARA for GSA.

WINGARD MP can:

  • Develop reusable libraries of charge types, films, laminates, glass types, airblast loadings, layups, frame and mullion cross-sections, and window systems.
  • Quickly switch between English and Metric units.
  • Interact with graphs (zoom, scale).
  • Copy and print all output.
  • Save graphs  in DPLOT format.
  • Run a single analysis for each system in the current project.
  • Analyze both single-pane and multi-pane window systems.
  • View the frame response of a multi-pane window in 3D.
  • Run multiple window systems at once.

WINGARD is not widely distributed. The program is generally reserved for employees of GSA; other U.S. government agencies; established U.S. blast, structural, and security consulting firms; or other U.S. firms involved with protective glazing. All users are highly encouraged to thoroughly read the technical and user manuals prior to using this program.
