Steel stud wall analysis code for blast response prediction [abstract]

Abstract

With the Okalahoma City Bombing a new urgency was created for the need to do research in the area of blast resistant building. With the turn of the century an ever greater threat appear with a need for more improve building resistance. The National Explosion Research Center located at the University of Missouri-Columbia has developed engineering guidelines for the design of blast-resistant steel stud wall systems. The portion of the project undertaken was compiling the 3 years of research and creating a computerized engineering design tool that allows an engineer the ability to design blast-resistant steel stud wall systems and to predict their performance under a specified blast threat. The program is called Steel Stud Wall Analysis Code (SSWAC). SSWAC is a user-friendly and menu-driven code that takes the specific user wall inputs and applies a single-degree of freedom (SDOF) dynamic model to calculate the response of the walls under blast. The program contains 7,088 lines of written code, 1,233 lines of calculation, 14 user windows, and 184 global variables.
