How to determine structural loads Part 2: Snow and rain loads in accordance with 2006 IBC

Chapter 16, Structural Design, of the 2006 International Building Code (IBC) prescribes minimum structural loading requirements that are to be used in the design of all buildings and structures. The intent is to subject buildings and structures to loads that are likely to be encountered during their life span, thereby minimizing hazard to life and improving performance during and after a design event....

Steel moment frames 101: What to consider when creating wide-open spaces

A building’s stability is a critical design element that structural engineers must understand. Structures dating back thousands of years have typically relied upon one of, or a combination of, three system types for stability: shearwall, braced frame, and/or moment frame. This article provides an introduction to the "wide-open spaces-friendly" moment-frame system in steel-framed structures.... Read More...

Blast-resistant design for buildings

The 1995 attack on the Oklahoma City Murrah Building served as a major impetus to raise government interest in blast protection for facilities in the United States. In response, the federal Interagency Security Committee (ISC) addressed the issue promptly by developing a blast-resistance standard outlining new criteria for design. Subsequently, the horrific structural collapses of Sept. 11, 2001, refocused attention and emphasis on design for extraordinary loads.
