Spacing of <br /> horizontai rebar not to exceed 48". <br /> 3. Defiection meets L/240. <br /> - 4. Additional reinforcement is required around openings,corners,and discontinuities. <br /> 5. The wa(1 must be braced against sway at tbe top and bottom. <br /> 6. The design criteria used include compoitents�nd cladding elements,an assumed importance factor of <br /> 1.0,a maximum mean roof height of 35',and buildings both enclosed or partially enclosed. <br /> 7. Exposure categorics(A, B,C,D) <br /> Exposure A—Large city centers with at least 50 percent of the buiidings having a height in excess of <br /> 70 feet. Use of this exposure category shall be limited to those areas for which terrain representative <br /> of Exposure A prevails in the upwind direction for a distance of at least 0.5 mile or 10 times the <br /> height of the building or other structure,whichever is greater. Possible channeling effects or <br /> increased veJocity pressures due to the building or structure being located in the wake of adjacent <br /> buildings shaU be taken into accoi,nt. <br /> Exaosure B--Urban and suburban areas,wooded areas,or other terrain with numerous closely <br /> spaced ubstnrctions having the size of singie-family dwel{ings or larger. Exposure B shall be <br /> assumed unless the site meets the definition of another type exposure. <br /> Eraosure C—Open terrain with scattered obstructions,including surtace undulations or other <br /> irregularities, having heights generalty less than 30 feet extending more tl�an 1,500 feet from the <br /> buiiding site in any quadrant. This exposare shall also apply to any bnilding located within exposure <br /> B type terrain where the buitding is directly adjacent to apen areas of Exposure C type terrain in any <br /> quadrant for a distance of more than 60d fcc� This catcgory includes flat open country,grasslands <br /> ` ' and shorelines in h�rricane-prone regions. <br /> 6-17 <br /> Issued on: 10/!/2003 <br /> Rclease: P <br />
