By James R. Kirby, AIA 04-02-2020. Wind design of roof systems is one of the more complicated things that an architect deals with during the design of a building. And with the latest version of ASCE 7, Minimum Design Loads For Buildings and Other Structures (ASCE 7), it has become that much more challenging for roof system.

In simple terms, C&C would be considered as windows, doors, the siding on a house, roofing material, etc. In Structural Design, the pressure exerted by the wind is the most important thing to be considered. A deflections perpendicular to the wind may occur to the building when a wind is passing through. This deflections depends on velocity of the wind. In a high or a tall structure, the load due to wind governs and wind loads should not be taken for granted. ASCE 7-16 set a standard in calculating.

Changes in ASCE 7-16. The biggest change from FBC 6 th Edition to FBC 7 th Edition is the new ASCE 7-16 reference standard. There are many significate changes to the wind load criteria within this standard. First, ASCE 7-10 had three wind speed maps, one for a Risk Category I, one for Risk Category II, and one for Risk Category III and IV. ASCE. ASCE 7 references risk category factors typically referenced in building codes (table 1.5.1 ASCE 7-10, ASCE 7-16). ASCE 7 officially defines risk category as A categorization of buildings and other structures for determination of flood, wind, snow, ice, and earthquake loads based on the risk associated with unacceptable performance Both the 2018 IBC and ASCE-SEI 7-16 became widely used in 2019. ASCE 7-16 uses basic wind speed, exposure categories, allowable stress load factor, mean roof height, door area, door location on the building and wind directionality factor to figure wind loads on doors. Wind load for a particular structure is also determined by its Risk Category
Revisions to ASCE 7-16. Eventually, we will all use ASCE 7-16 as the basis for determining design wind loads for our roofs. To that end, we will need to understand what has remained the same, what is changed, and what has been added to the latest version of ASCE 7. Basic differences between versions of ASCE http://skghoshassociates.com/For the full recording:http://shop.skghoshassociates.com/web-seminar-recordings/designing-for-asce-7-16-wind-loads-per-the-2018-.. A new Ground Elevation Factor is added in ASCE 7-16 to account for variations in air density at different altitudes. Entering the correct Ground Elevation above Sea Level can result, as an example, in 17% reduction in design wind loads in Denver Determining Wind Loads from the ASCE 7-16. Table 29.1-2 in the ASCE 7-16 outlines the necessary steps to determining the wind loads on a circular tank structure according to the Main Wind Force Resisting System (MWFRS).. Step 1: The Risk Category is determined from Table 1.5-1 based on the use or occupancy of the building. Dome structures may be utilized as storehouses which pose a relatively.
. Because the building is open and has a pitched roof, there are two wind directions to be considered: wind direction parallel to the slope and wind normal to the slope Design-wind loads are derived using the American Society of Civil Engineers (ASCE) Standard ASCE 7, Minimum Design Loads for Buildings and Other Structures. This standard is a widely recognized consensus standard and is referenced in and serves as the technical basis for wind load determination in the International Building Code and NFPA 5000. Wind load design cases as defined in Figure 27-4-8 of ASCE 7-10. Case 1: Full wind loads in two perpendicular directions considered separately. Case 2: 75% wind loads in two perpendicular directions with 15% eccentricity considered separately. Case 3: 75% wind loads in two perpendicular directions simultaneously

ASCE 7-10 Wind Provisions and Effects on Wood Design and Construction Philip Line, P.E.1 William L. Coulbourne, P.E. M.ASCE2 ABSTRACT It is well known that the major change for wind design in ASCE 7-10 Minimum Design Loads for Buildings and Other Structures is the introduction of new wind speed maps that are referred to as ultimate wind speed maps in the 2012 International Building Code (IBC) [SIZE=10.5pt] Hi Everybody! [/SIZE] [SIZE=10.5pt] I have a question about Chapter 28 (ASCE 7-10) and the simplified design wind pressure, Ps. I am having trouble understanding how to calculate Ps30 (Figure 28.6-1, pg 304). [/SIZE] [SIZE=10.5pt] On page 303, there seems to be two cases: A and B, each case shows the difference sections that experience wind pressure (sections A-H) loads. Typically, the base design loads are outlined by the code as a 2% annual probability of exceedence (2% in 50 years for seismic loads). Therefore, an elevated Importance Factor creates proportionally higher design loads (i.e., a wind Importance Factor of 1.15 is a 15% increase in design wind loads). * Reference ASCE 7-05 for further.
The Directional Procedure is the traditional wind design procedure that can be used for structures of any height. When we say it is the traditional wind design procedure, we mean that it has been around since the 1972 edition of the standard that is now ASCE 7, which at that time was ANSI Standard A58.1, ANSI standing for the American National Standards Institute Prepared by the ASCE Task Committee on Wind-Induced Forces of the Oil and Gas Committee of the Energy Division of ASCE. Wind Load Design for Petrochemical and Other Industrial Facilities, Second Edition, provides general guidelines for the computation of wind loads at petrochemical and other industrial facilities. Topics include Building Design for Wind Forces provides easy-to-follow summaries of complex ASCE 7-16 wind load provisions and shows how to apply the corresponding design procedures using practical examples. A detailed discussion of typical structural damage caused by extreme wind events such as hurricanes and tornadoes is presented along with design. This seminar is based on the ASCE publications Minimum Design Loads for Buildings and Other Structures (ASCE 7-16) and Significant Changes to the Wind Provisions of ASCE 7-16. While much of the instruction focuses on assessing wind loads, a portion of the seminar is directed to review wind damage experience of the past thirty years and lessons. This design guide provides guidance, in the form of three design examples, for three-dimensional (3-D) roof snowdrifts.

ASCE 7-16 ASCE 7-16's design wind-uplift load procedures are described and the basic design wind speed maps are provided in Chapter 26-Wind Loads: General Requirements. Design wind-uplift loads for roof assemblies typically are determined using ASCE 7-16's Chapter 30-Wind Loads: Components and Cladding . In order for a structure to be sound and secure, the foundation, roof, and walls must be strong and wind-resistant. When building a structure it is important to calculate wind load to ensure that the structure can withstand high winds, especially if the building is located in an area. ‐PV1‐2012: Seismic Design ‐PV2‐2012: Wind Design ASCE 7‐16 incorporates and adopts PV2‐2012 Solar PV • The SEAOC PV committee was formed in September 2011. • Goal: To address the lack of requirements in the code for PV systems. 2016: ‐PV2‐2016: Supersedes PV2‐2012 ‐References ASCE 7‐16
Range communities, designates ASCE 7-16 as a referenced standard. IBC 2018 / ASCE 7-16 contain significant changes relative to the wind load provisions of IBC 2015 / ASCE 7-10 that impact the determination of design wind loads in the Front Range region. These changes affect the use of the 2013 Colorado Front Range Gust Map to determine design STRUCTURAL DESIGN 408 2015 SEATTLE BUILDING CODE Vult= Ultimate design wind speeds (3-second gust), miles per hour (mph) (km/hr) determined from Figure 1609.3(1), 1609.3(2), 1609.3(3) or ASCE 7.

SECTION 160 When the limits of Low-rise buildings given in ASCE 7-05 Section 6.2 (for 2006/2009 IBC), in ASCE 7-10 Section 26.2 (for 2012/2015 IBC), and in ASCE 7-16 Section 26.2 (for 2018 IBC) are exceeded, or when selected by the user, wind loads will be calculated using the provisions for the rigid buildings of All Heights
10 and NBCC 2015; and shaped based on ASCE 7-16. Moreover, for large low-rise building with low heights, say 5 m, it was found that wind loads on the roof corner are approximately equal to those on the edge zone. Exceptions for low-rise buildings with large configurations and low-slope roofs are proposed for ASCE 7 and NBB Consequently, the strength design wind-load factor was changed to 1.0 in this version. Simply put, ASCE 7-10 and ASCE 7-16 use three and four maps respectively based on strength design in conjunction with a wind-load factor of 1.0, while ASCE 7-05 uses a single map with an importance factor and wind-load factor of 1.6. Because ASD results.
