#Breathable rafter tails design portable#

The deflection criterion for interior partitions is based on the horizontal load defined in Section 1607.15.

#Breathable rafter tails design portable#

Flexible, folding and portable partitions are not governed by the provisions of this section.For roofs, this exception only applies when the metal sheets have no roof covering. For secondary wall members supporting formed metal siding, the design wind load deflection shall not exceed l/90. For secondary roof structural members supporting formed metal roofing, the live load deflection shall not exceed l/150. For structural roofing and siding made of formed metal sheets, the total load deflection shall not exceed l/60.Where design for tornado loads is required, the design pressures shown shall be the maximum of wind or tornado pressures. Design wind pressures and their applicable zones with dimensions to be used for exterior component and cladding materials not specifically designed by the registered design professional responsible for the design of the structure, psf (kN/m 2).Applicable internal pressure coefficients and applicable tornado internal pressure coefficients.Applicable wind direction if more than one wind exposure is utilized.

Effective plan area, A e, for tornado design in accordance with Chapter 32 of ASCE 7.

Ultimate design wind speed, V ult, (3-second gust), miles per hour (km/hr), tornado speed, V T (mph) and nominal design wind speed, V asd, (mph) as determined in accordance with Section 1609.3.1.

The following information related to wind loads shall be shown, regardless of whether wind loads govern the design of the lateral force-resisting system of the structure:
