1.Determine the Design Wind Load
[1.1] Using the Analytical Method ‐ ASCE 7‐5
The procedure to determine Design Wind Load is specified by the American Society of Civil
Engineers (ASCE) and referenced in the International Building Code (IBC) 2006. For purposes of this document, the values, equations, and procedures used in this document reference ASCE
7‐5, Minimum Design Loads for Buildings and Other Structures. Please refer to ASCE 7‐5 if you have any questions about the definitions or procedures presented in this manual
The wind force analysis is based on ASCE 7‐5, Chapter 6. Upon review of the different methods available for calculating wind loading, it has been determined that Method 2 (Analytical
Procedure) is most appropriate. Specifically Section 6.5.13 (Design Wind Loads on Open Buildings with Mono sloped, pitched, or Troughed Roofs), was selected as the method most closely approaching the application of Solar Matrix racking system. The pressures are determined following Section 6.5.13.2 (Main Wind‐Force Resisting System) according to the following formula:
p = qh × G × Cn
Equation 1
Where p = design wind pressure (+ denotes down towards the roof)
qh = velocity pressure evaluated at mean roof height
G = gust effect factor as determined in ASCE 7‐5Section 6.5.8
Cn = net pressure coefficient determined from ASCE 7‐5 Fig.6‐18A, p.66.
[1.2] Determine the Velocity Pressure according 6.5.10
qz = qh = 0.00256 × Kz × Kzt × Kd × V^2 × I=17.63( lb/ft2,psf)
Wind Speed, V =100 mph(45m/s)
Importance Factor I = 1 (Table 6-1)
Direct. Factor, Kd = 0.85 (Table 6-4)
Topo. Factor, Kzt = 1.00 (Sect.6.5.7)
Topographic Factor, Kz= 0.81 (Table 6-3)

随着太阳能使用情况的增多，生产销售太阳能的厂家也越来越多。所以在市场上需求逐渐增大，所以出现了太阳能配件产品-太阳能光伏压块。那么今天小编给大家打听到一个好消息，太阳能光伏压块的价格2017年元旦有活动哦，快来围观吧。我有好消息迫不及待的想要告诉你。
据调查显示，河北是中国太阳能光伏压块生产的厂家最多的地方，河北生产太阳能光伏压块的厂家不仅只生产太阳能光伏压块，还会生产太阳能工作中会使用的其他配件，比如光伏压块、光伏组件压块、铝合金边压块、光伏支架压块等一些其他种类的太阳能器械使用配件。随着市场需求的曾多，生产太阳能光伏压块的厂家也越来越多，为了扩大自己的知名度，河北太阳能光伏压块厂家决定在2017年元旦的时候给新老顾客一个元旦大礼包。一般来说送点小礼物肯定是没大意思的，也只是一个噱头。河北太阳能光伏压块厂家决定元旦给大家需要的太阳能光伏压块、以及自己公司生产的其他太阳能产品打折。面对这么大的诱惑，你还只是驻足观望吗？
