Brace Yourself for the 2006 IBC
The 2006 International Building Code (IBC) is coming and for some jurisdictions it is already here. Las Vegas has already seen its adoption; Northern Nevada and California are close behind. BJG has studied up and is providing you with the following story of the 2006 IBC and your building’s braced frame particularly with respect to industrial buildings.
Not so long ago, the concentric braced frame was a thing of simplicity and reliability. Inexpensive to implement and relatively simple to design, it was an important system of choice for economical structures where the architectural floor plan could accommodate the brace layout. Several typical braced frame configurations are shown immediately below and will be discussed later where appropriate.
A typical braced frame “works” by transferring horizontal forces to foundations by pushing or pulling on the diagonal steel member. See Figure 8 for an illustration. Engineers have tried many varieties of braced frames over the centuries. Some have performed well, some have performed poorly and some have been “just ok”. Much of what we have learned has been by seeing what does and does not work in earthquakes. (more…)
