Title:Companion Manual to the Windstorm Mitigation Manual for Light Fram Construction
Author(s):Wickersheimer, David
Wind mitigation
Abstract:The information contained in chapter 1 is intended to establish the difference between tornado and straight-line winds. It explains a comprehensive wind design program initiated by the Building Safety Division of the City of Urbana, IL. The program was intended to educate the public, the residential construction industry and the design professionals within the community about the importance of wind resistant wood framed construction. It charts the cost of wind resistant construction for two distinctly different categories of home. Chapter 2 reviews the structural planning issues for resistance to wind uplift which is the tension chain from roof to foundation. Two techniques are emphasized: total structural panel approach and total metal connector approach. Chapter 3 reviews the structural planning issues related to the stability of the residence subjected to wind load, overturning and sliding. It introduces the concept of a diaphragm, a shear wall and a drag strut. This Chapter illustrates and explains the behavior of each stability issue and why each presents a problem in construction. The Chapter tells how to design to resist the effects of overturning and sliding. It conceptually reviews two examples to further clarify the stability concepts. Chapter 4 develops a detailed wind uplift design procedure with illustrations. The procedure is for a generic house design. A numerical example is worked to aid familiarity with the procedure, and employs use of Appendix A Tables. The Tables work with this chapter to minimize much of the actual mathematics. Chapter 5 develops a detailed wind stability design procedure, again with illustrations, to explain the Tables found in Appendix B. A numerical example is worked in total, incorporating all of the tables of Appendix B.
