Understanding Code Requirements for Panic Hardware
By Lori Greene, AHC/CDC, CCPR, FDAI, FDHI
Panic hardware, also known as an exit device, is designed to provide building occupants fast and easy egress in an emergency. Due to its durability and ease of use, panic hardware is commonly installed in places where it isn’t required by code. Despite its popularity, many specifiers continually struggle with knowing when panic hardware required by code. …

Curtain walls are often the focal point of aesthetic design for a multi-story building. Behind the attractive façade are the pedestrian, yet arguably more important, functional components that ensure safety and reliability—fasteners that transfer loads both imposed and experienced by the assembly to the building’s structural framework.

Architectural and engineering firms are increasingly exploring stainless steel’s possibilities as a structural material as new research, structural codes, and design guides become available. Most designs have used the familiar Types 304L or 316L alloys from the austenitic family of stainless steels, but for all but the lightest sections, the duplex stainless steel family presents a much greater potential for innovation.

Weighty Matters: An overview of in-situ load testing

featured`

In-situ load testing is a powerful tool to assess the performance of structures with respect to their ability to carry code-prescribed loads. The practice dates back to the late 1800s and has been used to verify the load rating of structures, as well as the expected performance of structures in retrofit, repair, and strengthening applications.
