Loads & Trusses
 |
Learn more about:
There are different types of loads that act on structures:
Live Loads – occupants and moveable objects in or on the structure
Dead Loads – weight of the building materials and the structure itself
Environmental Loads – created by snow, wind, and earthquake (seismic) forces
|

Truss Manufacturers and Designers are not responsible for determining these loads for structures; they must be specified by the Building Designer (see the Technical Info section for more on Design Responsibilities). Publications that aid Building Designers in load determination are ASCE 7 – Minimum Design Loads for Buildings and Other Structures, the International Building Code and the International Residential Code. The following resources are offered to Building Designers to aid in determining loads on structures and to Truss Manufacturing personnel to enhance their understanding of the load determination process.

The American Wood Council (AWC) has developed a new series of easy-to-use Guides to Wood Construction in High Wind Areas. Separate documents address wind design requirements in 90, 100, 110, 120, and 130 mph wind zones. These Guides are based on provisions contained in AF&PA's Wood Frame Construction Manual (WFCM) for One- and Two-Family Dwellings, 2001 Edition, the reference document for high-wind wood-frame construction in the International Residential Code (IRC). Use of the high wind provisions of these Guides will result in design solutions that prescriptively meet the requirements of the WFCM and the IRC.
